554c06ba3e cpuidle: remove en_core_tk_irqen flag
The en_core_tk_irqen flag is set in all the cpuidle driver which
means it is not necessary to specify this flag.

Remove the flag and the code related to it.

3dcb9f1b17 ARM: OMAP3: remove cpuidle_wrap_enter
In a previous commit the en_core_tk_irqen flag has been added but we missed
the cpuidle_wrap_enter which was doing the job to measure the time for the
'omap3_enter_idle' function.

Actually, I don't see any reason to use this wrapper in the code. In the better
case, the time computation is not correctly done because of the different
operations done in omap3_enter_idle_bm which were not taken into account
before the en_core_tk_irqen flag was set.

As the time is reflected for the state overridden by the omap3_enter_idle_bm,
using the wrapper is pointless now, so removing it.

cd4cb1a7df Display related clean-up from Tomi Valkeinen.
These were separated from the DSS driver changes to leave out
 a dependency between the driver and arch/arm related code.
 
 As agreed on the mailing lists, these are based on Tomi's
 platform_data header branch at:
 
 git://gitorious.org/linux-omap-dss2/linux.git 3.10/0-dss-headers
 
 Note that these patches have already been in Linux next via
 Tomi's tree. As Tomi's driver changes are getting merged via
 the drm tree because of another dependency, these should get
 merged via the ARM SoC tree.
 
 Apologies for the late pull request on this one, this dependency
 should have been cleared away earlier.

This has a nasty set of conflicts with the exynos MCT code, which was
moved in a separate branch, and then fixed up when merged in, but still
conflicts a bit here. It should have been sorted out by this merge though.

0583fe478a ARM: convert arm/arm64 arch timer to use CLKSRC_OF init
This converts arm and arm64 to use CLKSRC_OF DT based initialization for
the arch timer. A new function arch_timer_arch_init is added to allow for
arch specific setup.

This has a side effect of enabling sched_clock on omap5 and exynos5. There
should not be any reason not to use the arch timers for sched_clock.

mandatory clock for usb phy attached to ocp2scp and hence made as the main
clock for ocp2scp.

49ded525d4 cpufreq: OMAP: instantiate omap-cpufreq as a platform_driver
As multi-platform build is being adopted by more and more ARM platforms,
initcall function should be used very carefully.  For example, when
CONFIG_ARM_OMAP2PLUS_CPUFREQ is built in the kernel, omap_cpufreq_init()
will be called on all the platforms to initialize omap-cpufreq driver.

Further, on OMAP, we now use Soc generic cpufreq-cpu0 driver using device
tree entries.  To allow cpufreq-cpu0 and omap-cpufreq drivers to co-exist
for OMAP in a single image, we need to ensure the following:
 1. With device tree boot, we use cpufreq-cpu0
 2. With non device tree boot, we use omap-cpufreq

In the case of (1), we will have cpu OPPs and regulator registered
as part of the device tree nodes, to ensure that omap-cpufreq
and cpufreq-cpu0 don't conflict in managing the frequency of the
same CPU, we should not permit omap-cpufreq to be probed.

In the case of (2), we will not have the cpufreq-cpu0 device, hence
only omap-cpufreq will be active.

To eliminate this undesired these effects, we change omap-cpufreq
driver to have it instantiated as a platform_driver and register
"omap-cpufreq" device only when booted without device tree nodes on
OMAP platforms.

This allows the following:
 a) Will only run on platforms that create the platform_device
    "omap-cpufreq".
 b) Since the platform_device is registered only when device tree nodes
    are *not* populated, omap-cpufreq driver does not conflict with
    the usage of cpufreq-cpu0 driver which is used on OMAP platforms when
    device tree nodes are present.

Inspired by commit 5553f9e26f
(cpufreq: instantiate cpufreq-cpu0 as a platform_driver)

4c3ffffdbc ARM: Push selects for TWD/SCU into machine entries
The TWD and SCU configs are selected by default as long as
MSM_SCORPIONMP is false and/or MCT is false. Implementing the
logic this way certainly saves lines in the Kconfig but it
precludes those machines which select MSM_SCORPIONMP or MCT from
participating in the single zImage effort because when those
machines are combined with other SMP capable machines the TWD and
SCU are no longer selected by default.

Push the select out to the machine entries so that we can compile
these machines together and still select the appropriate configs.

72433ebada ARM: OMAP4: PM: Avoid expensive cpu_suspend() path for all CPU power states except off
Current CPU PM code code make use of common cpu_suspend() path for all the
CPU power states which is not optimal. In fact cpu_suspend() path is needed
only when we put CPU power domain to off state where the CPU context is lost.

Update the code accordingly so that the expensive cpu_suspend() path
can be avoided for the shallow CPU power states like CPU PD INA/CSWR.

The patch has been tested on OMAP4430 and OMAP5430(with few out of tree patches)
devices for suspend and CPUidle.

e745725349 ARM: OMAP4+: CPUidle: Deprecate use of omap4_mpuss_read_prev_context_state()
Current OMAP4 CPUIdle driver is using omap4_mpuss_read_prev_context_state()
to check whether the MPU cluster lost context or not before calling
cpu_cluster_pm_exit().  This was initially done an optimization for
corner cases, where if the cluster low power entry fails for some
reason, the cluster context restore gets skipped.  However, since
reading the previous context is expensive (involving slow accesses to
the PRCM), it's better to avoid it and simply check the target cluster
state instead.

Moving forward, OMAP CPUidle drivers needs to be moved to drivers/idle/*
once the PRM/CM code gets moved to drivers. This patch also reduces one
dependency with platform code for idle driver movement.

board-omap3encore.o. But there's no Kconfig symbol MACH_ENCORE and
there's no file board-omap3encore.c. This line can safely be removed.

b7806dc7cb ARM: OMAP4+: PM: Restore CPU power state to ON with clockdomain force wakeup method
While waking up CPU from off state using clock domain force wakeup, restore
the CPU power state to ON state before putting CPU clock domain under
hardware control. Otherwise CPU wakeup might fail. The change is recommended
for all OMAP4+ devices though the PRCM weakness was observed on OMAP5
devices first.

As a result of weakness, lock-up is observed inside the hardware state
machine of local CPU PRCM and results are UN-predictable as per designers.
In software testing, we have seen hard-locks most of the time where system
gets frozen. With power domain state restored, system behaves correctly.

So update the code accordingly.

The dss-common file currently requests gpios required by the picodlp DPI
panel on the 4430sdp/blaze board. It also requests DISPLAY_SEL_GPIO and
DLP_POWER_ON_GPIO gpios which are board specific gpios to switch between lcd2
panel and picodlp, and setting intermediate power supplies for picodlp
respectively. These gpios are toggled through platform_enable/disable functions
called by the picodlp driver.

Remove the gpio requests for the gpios which are already requested by the panel
driver, and remove the platform callback functions and set the platform specific
gpios in such a way that lcd2 panel is selected for the LCD2 overlay manager and
the power supplies for picodlp are disabled.

that's the only panel driver available for the LCD2 overlay manager.

Out of sharp panel's configurable pins, all apart from resb_gpio are managed by
a CPLD on the display and set to a default value. Only the configurable pin is
passed to platform data.

The backlight GPIO doesn't go directly to the sharp panel, it is used to set up
a voltage supply which goes to the LED+ pin of the panel, hence it isn't passed
to panel as platform data, and configured in the board file itself. The
backlight used to previously toggle through the platform_enable/disable
callbacks, but now it is always on. This needs to be revisited.

84b00f0e28 ARM: OMAP2+: Allow GPMC probe to complete even if CS mapping fails
When the GPMC driver is probed, we call gpmc_mem_init() to see which
chip-selects have already been configured and enabled by the boot-loader
and allocate space for them. If we fail to allocate space for one
chip-select, then we return failure from the probe and the GPMC driver
will not be available.

Rather than render the GPMC useless for all GPMC devices, if we fail to
allocate space for one chip-select print a warning and disable the
chip-select. This way other GPMC clients can still be used.

There is no downside to this approach, because all GPMC clients need to
request a chip-select before they can use the GPMC and on requesting a
chip-select, if memory has not already been reserved for the chip-select
then it will be.

When booting with device-tree, retrieve GPMC settings for ONENAND from

stored in the gpmc-nand.c in the future once the migration to

The user must now specify the ONENAND device width in the device-tree

the device-tree binding documentation for ONENAND devices connected to
the GPMC to reflect this.

Please note that this does not include GPMC timings for ONENAND. The
timings are being calculated at runtime.

There is some legacy code that only enables read wait monitoring for
non-OMAP3 devices. There are no known OMAP3 device issues that prevent
this feature being enabled and so when booting with device-tree use the
wait-monitoring settings described in the device-tree blob.

device-tree binding. Add these parameters to the binding documentation
as well as code to read them. Also add either "-ps" or "-ns" suffix to
the GPMC timing properties to indicate whether the timing is in
picoseconds or nanoseconds.

The existing code in gpmc_read_timings_dt() is checking the value of
of_property_read_u32() and only is successful storing the value read
in the gpmc_timings structure. Checking the return value in this case
is not necessary and we can simply read the value, if present, and
store directly in the gpmc_timings structure. Therefore, simplify the
code by removing these checks.

The comment in the gpmc_read_timings_dt() function, "only for OMAP3430"
is also incorrect as it is applicable to all OMAP3+ devices. So correct
this too.

a0d8dde9cb OMAPDSS: panels: keep platform data of all panels in a single header
Structs for platform data of omapdss panels are found in headers in the
'include/video/' path. Board files populate these structs with platform
specific values, and the panel driver uses these to configure the panel.

Currently, each panel has it's own header in the above path. Move all the
omapdss panel platform data structs to a single header omap-panel-data.h.
This is useful because:

- All other omapdss panel drivers will be modified to use platform data. This
  would lead to a lot of panel headers usable only by omapdss. A lot of these
  platform data structs are trivial, and don't really need a separate header.
- Platform data would be eventually removed, and platform information would be
  passed via device tree. Therefore, omapdss panel platform data structs are
  temporary, and will be easier to remove if they are all in the same header.
- All board files will have to include the same header to configure a panel's
  platform data, that makes the board files more consistent.

24db7eccfb ARM: OMAP2+: Convert NAND to use gpmc_cs_program_settings()
Convert the OMAP2+ NAND code to use the gpmc_cs_program_settings()
function for configuring the various GPMC options instead of directly
programming the CONFIG1 register.

This moves the configuration of some GPMC options outside the
nand_gpmc_retime() because these options should only need to be set once
regardless of whether the gpmc timing is changing dynamically at runtime.
The programming of where the wait-pin is also moved slightly, but this
will not have any impact to existing devices as no boards are currently
setting the dev_ready variable.

aa8d4767da ARM: OMAP2+: Add function for configuring GPMC settings
The GPMC has various different configuration options such as bus-width,
synchronous or asychronous mode selection, burst mode options etc.
Currently, there is no common function for configuring these options and
various devices set these options by either programming the GPMC CONFIG1
register directly or by calling gpmc_cs_configure() to set some of the
options.

Add a new function for configuring all of the GPMC options. Having a common
function for configuring this options will simplify code and ease the
migration to device-tree.

Also add a new capability flag to detect devices that support the
address-address-data multiplexing mode.

9f8331562a ARM: OMAP2+: Add variable to store number of GPMC waitpins
The GPMC has wait-pin signals that can be assigned to a chip-select
to monitor the ready signal of an external device. Add a variable to
indicate the total number of wait-pins for a given device. This will
allow us to detect if the wait-pin being selected is valid or not.

When booting with device-tree read the number of wait-pins from the
device-tree blob. When device-tree is not used set the number of
wait-pins to 4 which is valid for OMAP2-5 devices. Newer devices
that have less wait-pins (such as AM335x) only support booting with
device-tree and so hard-coding the wait-pin number when not using
device-tree is fine.

When setting the GPMC device type, make sure any previous

For OMAP4+ devices MUXADDDATA is a 2-bit field (bits 9:8)
where as for OMAP2/3 devices it was only a one bit field
(bit 9). For OMAP2/3 devices bit 8 is reserved and the
OMAP documentation says to write a 0 to this bit. So
clearing bit 8 on OMAP2/3 devices should not be a problem.

2eb03937df ARM: OMAP3: Update clocksource timer selection
When booting with device-tree for OMAP3 and AM335x devices and a gptimer
is used as the clocksource (which is always the case for AM335x), a
gptimer located in a power domain that is not always-on is selected.
Ideally we should use a gptimer for clocksource that is located in a
power domain that is always on (such as the wake-up domain) so that time
can be maintained during a kernel suspend without keeping on additional
power domains unnecessarily.

In order to fix this so that we can select a gptimer located in a power
domain that is always-on, the following changes were made ...
1. Currently, only when selecting a gptimer to use for a clockevent
   timer, do we pass a timer property that can be used to select a
   specific gptimer. Change this so that we can pass a property when
   selecting a gptimer to use for a clocksource timer too.
2. Currently, when selecting either a gptimer to use for a clockevent
   timer or a clocksource timer and no timer property is passed, then
   the first available timer is selected regardless of the properties
   it has. Change this so that if no properties are passed, then a timer
   that does not have additional features (such as always-on, dsp-irq,
   pwm, and secure) is selected.

For OMAP3 and AM335x devices that use a gptimer for clocksource, change
the selection of the gptimer so that by default the gptimer located in
the always-on power domain is used for clocksource instead of
clockevents.

Please note that using a gptimer for both clocksource and clockevents
can have a system power impact during idle. The reason being is that
OMAP and AMxxx devices typically only have one gptimer in a power domain
that is always-on. Therefore when the kernel is idle both the clocksource
and clockevent timers will be active and this will keep additional power
domains on. During kernel suspend, only the clocksource timer is active
and therefore, it is better to use a gptimer in a power domain that is
always-on for clocksource.

Therefore, consolidate the definitions to simplify the code.

we still need to use the alias "sys_clkin_ck" for these devices.

a7990a1952 ARM: OMAP2+: Remove hard-coded test on timer ID
Currently, when configuring the clock-events and clock-source timers
for OMAP2+ devices, we check whether the timer ID is 12 before
attempting to set the parent clock for the timer.

This test was added for OMAP3 general purpose devices (no security
features enabled) that a 12th timer available but unlike the other
timers only has a single functional clock source. Calling
clk_set_parent() for this 12th timer would always return an error
because there is only one choice for a parent clock. Therefore,
this hard-coded timer ID test was added.

To avoid this timer ID test, simply check to see if the timer's current
parent clock is the desired parent clock and only call clk_set_parent()
if this is not the case.

Also if clk_get() fails, then use PTR_ERR() to return the error code.

Currently on boot, when displaying the name of the gptimer used for
clockevents and clocksource timers, the timer ID is shown. However,
when booting with device-tree, the timer ID is not used to select a
gptimer but a timer property. Hence, it is possible that the timer
selected when booting with device-tree does not match the ID shown.
Therefore, instead display the HWMOD name of the gptimer and use
the HWMOD name as the name of clockevent and clocksource timer (if a
gptimer is used).

469d633d20 ARM: OMAP: dpll: enable bypass clock only when attempting dpll bypass
omap3_noncore_dpll_set_rate() attempts an enable of bypass clk as well
as ref clk for every .set_rate attempt on a noncore DPLL, regardless of
whether the .set_rate results in the DPLL being locked or put in bypass.
Early at boot, while some of these DPLLs are programmed and locked
(using .set_rate for the DPLL), this causes an ordering issue.

For instance, on OMAP5, the USB DPLL derives its bypass clk from ABE DPLL.
If a .set_rate of USB DPLL which programmes the M,N and locks it is called
before the one for ABE, the enable of USB bypass clk (derived from ABE DPLL)
then attempts to lock the ABE DPLL and fails as the M,N values for ABE
are yet to be programmed.

To get rid of this ordering needs, enable bypass clk for a DPLL as part
of its .set_rate only when its being put in bypass, and only enable the
ref clk when its locked.
