cfd72a4c20 Merge branch 'drm-intel-next' of git://people.freedesktop.org/~danvet/drm-intel into drm-next
drm-intel-next-2014-01-10:
- final bits for runtime D3 on Haswell from Paul (now enabled fully)
- parse the backlight modulation freq information in the VBT from Jani
  (but not yet used)
- more watermark improvements from Ville for ilk-ivb and bdw
- bugfixes for fastboot from Jesse
- watermark fix for i830M (but not yet everything)
- vlv vga hotplug w/a (Imre)
- piles of other small improvements, cleanups and fixes all over

Note that the pull request includes a backmerge of the last drm-fixes
pulled into Linus' tree - things where getting a bit too messy. So the
shortlog also contains a bunch of patches from Linus tree. Please yell if
you want me to frob it for you a bit.

2aa63ce000 ARM: SoC fixes for 3.13-rc
Hopefully the last set of arm-soc fixes for 3.13, or at least only a
 few stray patches after this.
 
 There are a few fixes for Renesas platforms to fixup DMA masks (this
 started causing errors once the DMA API added checks for valid masks in
 3.13). Two more dealing with resources for MMC and PWM setup.
 
 There's also a few TI/OMAP/DRA fixes for smaller stuff and a fix for
 compilation failures on a PXA platform.

efea3403d4 ARM: 7931/1: Correct virt_addr_valid
The definition of virt_addr_valid is that virt_addr_valid should
return true if and only if virt_to_page returns a valid pointer.
The current definition of virt_addr_valid only checks against the
virtual address range. There's no guarantee that just because a
virtual address falls bewteen PAGE_OFFSET and high_memory the
associated physical memory has a valid backing struct page. Follow
the example of other architectures and convert to pfn_valid to
verify that the virtual address is actually valid. The check for
an address between PAGE_OFFSET and high_memory is still necessary
as vmalloc/highmem addresses are not valid with virt_to_page.

9928422fef ARM: pxa: fix USB gadget driver compilation regression
After commit 88f718e3fa
"ARM: pxa: delete the custom GPIO header" a compilation
error was introduced in the PXA25x gadget driver.
An attempt to fix the problem was made in
commit b144e4ab1e
"usb: gadget: fix pxa25x compilation problems"
by explictly stating the driver needs the <mach/hardware.h>
header, which solved the compilation for a few boards,
such as the pxa255-idp and its defconfig.

However the Lubbock board has this special clause in
drivers/usb/gadget/pxa25x_udc.c:

This include file has an implicit dependency on
<mach/irqs.h> having been included before <mach/lubbock.h>
was included.

Before commit 88f718e3fa
"ARM: pxa: delete the custom GPIO header" this implicit
dependency for the pxa25x_udc compile on the Lubbock was
satisfied by <linux/gpio.h> implicitly including
<mach/gpio.h> which was in turn including <mach/irqs.h>,
apart from the earlier added <mach/hardware.h>.

Fix this by having the PXA25x <mach/lubbock.h> explicitly
include <mach/irqs.h>.

7e367c18c0 ARM: OMAP2+: Fix LCD panel backlight regression for LDP legacy booting
Looks like the LCD panel on LDP has been broken quite a while, and
recently got fixed by commit 0b2aa8bed3 (gpio: twl4030: Fix regression
for twl gpio output). However, there's still an issue left where the panel
backlight does not come on if the LCD drivers are built into the
kernel.

Fix the issue by registering the DPI LCD panel only after the twl4030
GPIO has probed.

Commit 7d7e1eb (ARM: OMAP2+: Prepare for irqs.h removal) and commit
ec2c082 (ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ)
updated the way interrupts for OMAP2/3 devices are defined in the
HWMOD data structures to being an index plus a fixed offset (defined
by OMAP_INTC_START).

Couple of irqs in the OMAP2/3 hwmod data were misconfigured completely
as they were missing this OMAP_INTC_START relative offset. Add this
offset back to fix the incorrect irq data for the following modules:
	OMAP2 - GPMC, RNG
	OMAP3 - GPMC, ISP MMU & IVA MMU

to using the requsite hwmod CONFIG_DEBUG_OMAPxUARTy FLAGS.

On DRA7 though, we seem to be missing this flag, and atleast on the DRA7 EVM
where we use uart1 for console, boot fails with DEBUG_LL enabled.

 There's also a fix that resolves some misdescribed GPIO controller
 resources on shmobile. The rest are mostly smaller fixes, a couple of

d721a15c30 ARM: shmobile: r8a7790: fix shdi resource sizes
The r8a7790.dtsi file has four sdhi nodes which the first two have the wrong
resource size for their register block. This causes the sh_modbile_sdhi driver
to fail to communicate with card at-all.

Change sdhi{0,1} node size from 0x100 to 0x200 to correct these nodes
as per Kuninori Morimoto's response to the original patch where all four
nodes where changed. sdhi{2,3} are the correct size.

This bug has been present since sdhi resources were added to the r8a7790 by
8c9b1aa418 ("ARM: shmobile: r8a7790: add MMCIF and SDHI DT
templates") in v3.11-rc2.

b03bb79d4f ARM: tegra: implement common DMA and resets DT bindings
This series converts the Tegra DTs and drivers to use the common/
 standard DMA and reset bindings, rather than custom bindings. It also
 adds complete documentation for the Tegra clock bindings without
 actually changing any binding definitions.
 
 This conversion relies on a few sets of patches in branches from outside
 the Tegra tree:
 
 1) A patch to add an DMA channel request API which allows deferred probe
    to be implemented.
 
 2) A patch to implement a common part of the of_xlate function for DMA
    controllers.
 
 3) Some ASoC patches (which in turn rely on (1) above), which support
    deferred probe during DMA channel allocation.
 
 4) The Tegra clock driver changes for 3.14.
 
 Consequently, this branch is based on a merge of all of those external
 branches.
 
 In turn, this branch is or will be pulled into a few places that either
 rely on features introduced here, or would otherwise conflict with the
 patches:
 
 a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid
    conflicts.
 
 b) The DRM tree, which introduces new code that relies on the reset
    controller framework introduced in this branch, and to avoid

cb12057256 ARM: s3c64xx: dt: Fix boot failure due to double clock initialization
Commit

4178bac ARM: call of_clk_init from default time_init handler

added implicit call to of_clk_init() from default time_init callback,
but it did not change platforms calling it from other callbacks, despite
of not having custom time_init callbacks. This caused double clock
initialization on such platforms, leading to boot failures. An example
of such platform is mach-s3c64xx.

This patch fixes boot failure on s3c64xx by dropping custom init_irq
callback, which had a call to of_clk_init() and moving system reset
initialization to init_machine callback. This allows us to have
clocks initialized properly without a need to have custom init_time or
init_irq callbacks.
