e57f35d45f fbcon: convert last fbcon_takeover call to do_fbcon_takeover
After commit 054430e773 (fbcon: fix locking harder),
there is only one place use do_fbcon_takeover now, this patch
convert it to do_fbcon_takeover too, then we can delete
fbcon_takeover whos function can be achieved with do_fbcon_takeover
easily to reduce code size and duplication.

8c090cfbf9 staging/solo6x10: depend on CONFIG_FONTS
The new SOLO6X10 driver needs the built-in console fonts, specifically
the VGA8x16 font and building it without console support results in
a link error error.

drivers/built-in.o: In function `solo_osd_print':
 :(.text+0x7d3424): undefined reference to `find_font'

This adds a dependency on the CONFIG_FONTS symbol and changes the
console code to always build the base driver even if there are
no specific fonts built-in.

a85f1a41f0 fbcon: queue work on power efficient wq
fbcon uses workqueues and it has no real dependency of scheduling these on the
cpu which scheduled them.

On a idle system, it is observed that and idle cpu wakes up many times just to
service this work. It would be better if we can schedule it on a cpu which the
scheduler believes to be the most appropriate one.

This patch replaces system_wq with system_power_efficient_wq.

daf799cca8 Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:

 - More work on DT support for various platforms

 - Various fixes that were to late to make it straight into 3.9

 - Improved platform support, in particular the Netlogic XLR and
   BCM63xx, and the SEAD3 and Malta eval boards.

 - Support for several Ralink SOC families.

 - Complete support for the microMIPS ASE which basically reencodes the
   existing MIPS32/MIPS64 ISA to use non-constant size instructions.

 - Some fallout from LTO work which remove old cruft and will generally
   make the MIPS kernel easier to maintain and resistant to compiler
   optimization, even in absence of LTO.

 - KVM support.  While MIPS has announced hardware virtualization
   extensions this KVM extension uses trap and emulate mode for
   virtualization of MIPS32.  More KVM work to add support for VZ
   hardware virtualizaiton extensions and MIPS64 will probably already
   be merged for 3.11.

Most of this has been sitting in -next for a long time.  All defconfigs
have been build or run time tested except three for which fixes are being
sent by other maintainers.

d7321df327 video: mxsfb: Adapt to new videomode API
commit 6cd2c7db4 (videomode: videomode_from_timing work) changed the name of
the function from videomode_from_timing() to videomode_from_timings().

commit 32ed6ef1 (videomode: create enum for videomode's display flags) changed
the 'data_flags' field in videomode structure to 'flags'

Adapt to these changes in order to fix the following errors:

drivers/video/mxsfb.c:761:3: error: too many arguments to function 'videomode_from_timing'
drivers/video/mxsfb.c:761:7: error: void value not ignored as it ought to be

drivers/video/mxsfb.c:770:9: error: 'struct videomode' has no member named 'data_flags'

Also, select VIDEOMODE_HELPER instead of OF_VIDEOMODE, as this one is
deprecated.

5647ac0ad4 Removal of GENERIC_GPIO for v3.10
GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
 cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
 possible to do so which has been causing confusion and breakage. This
 branch does the work to completely eliminate GENERIC_GPIO.
 
 However, it is not trivial to just create a branch to remove it. Over
 the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
 added to linux-next that conflicts with this branch. The following must
 be done to resolve the conflicts when merging this branch into mainline:
 
 * "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
   replaced with CONFIG_GPIOLIB
 * "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
   documentation.
 * Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
 * definitions of the option in architecture Kconfig code should be deleted.
 
 Stephen has 3 merge fixup patches[1] that do the above. They are currently
 applicable on mainline as of May 2nd.

88564dda0e MIPS: remove obsolete Kconfig macros
The support for PB1100, PB1500, and PB1550 got merged into the code for
DB1000 and DB1550 code in v3.7. When that was done the three related
Kconfig symbols were dropped. But not all related Kconfig macros were
removed. Do so now.

Note that the PB1100 code in the Au1100 LCD driver is removed entirely
and not converted to use its current Kconfig macro. That is done because
the macros it uses (PB1100_G_CONTROL, PB1100_G_CONTROL_BL, and
PB1100_G_CONTROL_VDD) are never defined. Actually only one of these was
ever defined (PB1100_G_CONTROL) but that define was removed in v2.6.34.
So, as far as I can tell, this code could have never compiled.

6fa52ed33b ARM: arm-soc driver changes for 3.10
This is a rather large set of patches for device drivers that for one
 reason or another the subsystem maintainer preferred to get merged
 through the arm-soc tree. There are both new drivers as well as
 existing drivers that are getting converted from platform-specific
 code into standalone drivers using the appropriate subsystem
 specific interfaces.
 
 In particular, we can now have pinctrl, clk, clksource and irqchip
 drivers in one file per driver, without the need to call into
 platform specific interface, or to get called from platform specific
 code, as long as all information about the hardware is provided
 through a device tree.
 
 Most of the drivers we touch this time are for clocksource. Since
 now most of them are part of drivers/clocksource, I expect that we
 won't have to touch these again from arm-soc and can let the
 clocksource maintainers take care of these in the future.
 
 Another larger part of this series is specific to the exynos platform,
 which is seeing some significant effort in upstreaming and
 modernization of its device drivers this time around, which
 unfortunately is also the cause for the churn and a lot of the
 merge conflicts.
 
 There is one new subsystem that gets merged as part of this series:
 the reset controller interface, which is a very simple interface
 for taking devices on the SoC out of reset or back into reset.
 Patches to use this interface on i.MX follow later in this merge
 window, and we are going to have other platforms (at least tegra
 and sirf) get converted in 3.11. This will let us get rid of
 platform specific callbacks in a number of platform independent
 device drivers.

dfbc32316c OMAPFB: defer probe if no displays
omapfb requires the panel drivers to have been probed when omapfb is
initialized. omapfb does not support insertion of new panels after its
probe. This causes a problem in case omapdss or the panel probes have
been deferred due to EPROBE_DEFER error, as omapfb won't find any
displays.

As a quick fix, this patch changes the omapfb probe so that if omapfb
does not find any displays, it'll return EPROBE_DEFER. This is not
perfect, as with a board with no displays, omapfb will get deferred
forever. Also, if the board has multiple displays, but only some of them
have been probed, omapfb will start and leave the unprobed displays out.

Commit 100c826235 (OMAPDSS: DPI: use new

in the kernel configuration.

Fix compilation by adding dummy inline functions for the ones that dpi.c
references. The functions will never be called, as dpi.c knows that
there is no DSI device available.

The 'load_new_rom_data' was used for checking whether new ROM data should
be updated or not.

However, we can decide it with 'size_program' data.  If the size is
greater than 0, it means updating ROM area is required.  Otherwise, the
default ROM data will be used.  Therefore, this duplicate platform data
can be removed.

0b81857339 backlight: lp855x: move backlight mode platform data
The brightness of LP855x devices is controlled by I2C register or PWM
input .  This mode was selected through the platform data, but it can be
chosen by the driver internally without platform data configuration.

How to decide the control mode:
  If the PWM period has specific value, the mode is PWM input.
  On the other hand, the mode is register-based.
  This mode selection is done on the _probe().

Move 'mode' from a header file to the driver private data structure,
'lp855 x'.  And correlated code was replaced.

currently the driver does not support any way of doing this.  This patch
adds a probe() callback to plat_lcd_data which platform LCD devices can
set to indicate that device-specific initialization is needed.

Fix three typos (originally) introduced by commit a9a84c37d1
("atmel_lcdfb: backlight control").

Two of these typos were introduced in v2.6.25.  (The third was
introduced in 915190f7d4 ("[ARM] 5614/1: at91: atmel_lcdfb: add
at91sam9g10 support to atmel LCD driver")).  Checking these commits
reveals that the default value of 'y' has never been set automatically
in all releases since v2.6.25! Perhaps this line might as well be
dropped.

    fbcon: don't lose the console font across generic->chip driver switch

uses a pointer in vc->vc_font.data to load font into the new driver.
However if the font is actually freed, we need to clear the data
so that we don't reload font from dangling pointer.

fc9bbca8f6 vm: convert fb_mmap to vm_iomap_memory() helper
This is my example conversion of a few existing mmap users.  The
fb_mmap() case is a good example because it is a bit more complicated
than some: fb_mmap() mmaps one of two different memory areas depending
on the page offset of the mmap (but happily there is never any mixing of
the two, so the helper function still works).

2c6360fb41 OMAPDSS: DPI: widen the pck search when using dss fck
When not using DSI PLL to generate the pixel clock, but DSS FCK, the
possible pixel clock rates are rather limited. DSS FCK is currently used
on OMAP2 and OMAP3.

When using Beagleboard with a monitor that supports high resolutions,
the clock rates do not match (at least for me) for the monitor's pixel
clocks within the current threshold in the code, which is +/- 1MHz.

This patch widens the search up to +/- 15MHz. The search is done in
steps, i.e. it first tries to find a rather exact clock, than a bit less
exact, etc. so this should not change the cases where a clock was
already found.

648a55e125 OMAPDSS: fix dss_fck clock rate rounding
DSS func clock is calculated with prate / div * m. However, the current
omapdss code calculates it with prate * m / div, which yields a slightly
different result when there's a remainder. For example, 432000000 / 14 *
2 = 61714284, but 432000000 * 2 / 14 = 61714285.

In addition to that, the clock framework wants the clock rate given with
clk_set_rate to be higher than the actual (truncated) end result. So, if
prate is 432000000, and div is 14, the real result is 30857142.8571...
We need to call clk_set_rate with 30857143, which gives us a clock of
30857142. That's why we need to use DIV_ROUND_UP() when calling
clk_set_rate.

This patch fixes the clock calculation.

38dd2daf29 drivers/video: fsl-diu-fb: add hardware cursor support
The Freescale DIU supports a 32x32 color hardware cursor.  Framebuffer
cursors are monochrome, so the driver converts the image data to the
format that the DIU expects and then programs to hardware accordingly.

The support cursor enabling/disabling, we provide two cursor image buffers.
One is always blank (all zeroes), and the other contains the real cursor
image data.  To disable the cursor (used typically for cursor blinking),
we just tell the hardware to use the blank cursor data.

d0df9a2c8f OMAPDSS: DISPC: Revert to older DISPC Smart Standby mechanism for OMAP5
DISPC on OMAP5 has a more optimised mechanism of asserting Mstandby to achieve
more power savings when DISPC is configured in Smart Standby mode. This
mechanism leads to underflows when multiple DISPC pipes are enabled.

There is a register field which can let us revert to the older mechanism of
asserting Mstandby. Configure this field to prevent underflows.

c35eeb2e80 OMAPDSS: DISPC: Configure doublestride for NV12 when using 2D Tiler buffers
When using a DISPC video pipeline to a fetch a NV12 buffer in a 2D container, we
need to set set a doublestride bit in the video pipe's ATTRIBUTES register. This
is needed because the stride for the UV plane(using a 16 bit Tiler container) is
double the stride for the Y plane(using a 8 bit Tiler container) for the 0 or
180 degree views. The ROW_INC register is meant for the Y plane, and the HW will
calculate the row increment needed for the UV plane by using double the stride
value based on whether this bit is set or not.

Set the bit when we are using a 2D Tiler buffer and when rotation is 0 or 180
degrees. The stride value is the same for 90 and 270 degree Tiler views, hence
the bit shouldn't be set.

3729a70b58 omapdss: Features: Fix some parameter ranges
Increase the DSS_FCLK and DSI_FCLK max supported frequencies, these come because
some frequencies were increased from OMAP5 ES1 to OMAP5 ES2. We support only
OMAP5 ES2 in the kernel, so replace the ES1 values with ES2 values. Increase the
DSI PLL Fint range, this was previously just copied from the OMAP4 param range
struct.

ca5ca69cab omapdss: DISPC: add max pixel clock limits for LCD and TV managers
Each version of OMAP has a limitation on the maximum pixel clock frequency
supported by an overlay manager. This limit isn't checked by omapdss. Add
dispc feats for lcd and tv managers and check whether the target timings can
be supported or not.

The pixel clock limitations are actually more complex. They depend on which OPP
OMAP is in, and they also depend on which encoder is the manager connected to.
The OPP dependence is ignored as DSS forces the PM framework to be on OPP100
when DSS is enabled, and the encoder dependencies are ignored by DISPC for now.
These limits should come from the encoder driver.

The OMAP2 TRM doesn't mention the maximum pixel clock limit. This value is left
as half of DSS_FCLK, as OMAP2 requires the PCD to be atleast 2.

Instead of using a custom binding for retrieving the GPIO that activates the

This approach has the advantage to be more generic.

For example: in the case of a board that has a PMIC supplying the LCD voltage,
the current approach would not work, as it only searches for a GPIO pin.

a1655100dd AUO-K190x: Use correct line length
Previously all functions that used the line length used xres directly,
thus hardcoding a 8bits per pixel value.

This patch calculates the correct line length according to the actual
bits per pixel value and changes all line length users to use the
calculated line length value.

7ab0a48420 video: fb: vt8500: Convert framebuffer drivers to standardized binding
Now that a display timing binding is available, convert our almost identical
binding to use the standard binding.

This patch converts the vt8500 and wm8505 framebuffer drivers and
associated dts/dtsi files to use the standard binding as defined in
bindings/video/display-timing.txt.

There are two side-effects of making this conversion:

1) The fb node should now be in the board file, rather than the soc file as
the display-timing node is a child of the fb node.

2) We still require a bits per pixel property to initialize the framebuffer
for the different lcd panels. Rather than including this as part of the
display timing, it is moved into the framebuffer node.

I have also taken the opportunity to alphabetise the includes of each
driver to avoid double-ups.

9e340fdc5a drivers/video/wm8505fb.c: use devm_ functions
The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

The patch makes some other cleanups.  First, the original code used
devm_kzalloc, but kfree.  This would lead to a double free.  The problem
was found using the following semantic match (http://coccinelle.lip6.fr/):

// <smpl>
@@
expression x,e;
@@
x = devm_kzalloc(...)
... when != x = e
?-kfree(x,...);
// </smpl>

The error-handing code of devm_request_and_ioremap does not print any
warning message, because devm_request_and_ioremap does this.

The call to dma_alloc_coherent is converted to its devm equivalent,
dmam_alloc_coherent.  This implicitly introduces a call to
dmam_free_coherent, which was completly missing in the original code.

A semicolon is removed at the end of the error-handling code for the call
to dma_alloc_coherent.

The block of code calling fb_alloc_cmap is moved below the block of code
calling wm8505fb_set_par, so that the error-handing code of the call to
wm8505fb_set_par can just return ret.  This way there is only one block of
error-handling code that needs to call fb_dealloc_cmap, and so this is
moved up to the place where it is needed, eliminating the need for all
gotos and labels in the function.  This was suggested by Tony Prisk.

The initializations of fbi and ret at the beginning of the function are not
necessary and are removed.  The call platform_set_drvdata(pdev, NULL); at
the end of the function is also removed.

the sources of all DSI channels to L4. However, we don't update the
value in the dsi_data, so we may end up with a different value in the
register and in the dsi_data, leading to DSI problems.

This patch fixes the issue by initializing also the channel source in
the dsi_data.

b7dec9b66f OMAPDSS: DSI: delay dispc initialization
We currently setup both DSI and DISPC related things when the DSI bus is
enabled. There's no need for DISPC related thing at that point, though,
but only later when the video output is enabled.

To make it possible to use the DSI bus before DISPC overlay manager is
selected, this patch moves DSI's DISPC initialization to
dsi_enable_video_output(), from omapdss_dsi_display_enable(). We also
move the selection of DISPC's LCD clock to dsi_enable_video_output.

This way there are no DISPC dependencies until the video output is
enabled.

2eea5ae6c1 OMAPDSS: add output->dispc_channel
The DISPC channel used for each output is currently passed in panel
platform data from the board files.

To simplify this, and to make the panel drivers less dependent on OMAP,
this patch changes omapdss to resolve the channel independently. The
channel is resolved based on the OMAP version and, in case of DSI, the
DSI module id. This resolved channel is stored into a new field in
output, dispc_channel.

The few places where dssdev->channel was used are changed to use
output->recommended_channel. After this patch, dssdev->channel is
obsolete.
