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)

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.

Samsung Clock fixes for 3.13-rc7
* Several patches fixing up incorrectly defined register addresses and
bitfield offsets that could lead to undefined operation when accessing
respective registers or bitfields.
1) clk: exynos5250: fix sysmmu_mfc{l,r} gate clocks
2a) clk: samsung: exynos5250: Fix ACP gate register offset
2b) clk: samsung: exynos5250: Add MDMA0 clocks
2c) ARM: dts: exynos5250: Fix MDMA0 clock number
3) clk: samsung: exynos4: Correct SRC_MFC register
All three issues have been present since Exynos5250 and Exynos4 clock
drivers were added by commits 6e3ad26816b72 ("clk: exynos5250:
register clocks using common clock framework") and e062b571777f5
("clk: exynos4: register clocks using common clock framework")
respectively.
* Patch to fix automatic disabling of Exynos5250 sysreg clock that could
cause undefined operation of several peripherals, such as USB, I2C,
MIPI or display block.
4) clk: samsung: exynos5250: Add CLK_IGNORE_UNUSED flag for the sysreg
clock
Present since Exynos5250 clock drivers was added by commits
6e3ad26816b72 ("clk: exynos5250: register clocks using common clock
framework").
* Patch fixing compilation warning in clk-exynos-audss driver when
CONFIG_PM_SLEEP is disabled.
5) clk: exynos: File scope reg_save array should depend on PM_SLEEP
Present since the driver was added by commit 1241ef94ccc3 ("clk:
samsung: register audio subsystem clocks using common clock
framework").

Due to incorrect clock specified in MDMA0 node, using MDMA0 controller
could cause system failures, due to wrong clock being controlled. This
patch fixes this by specifying correct clock.

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
8c9b1aa41853272a ("ARM: shmobile: r8a7790: add MMCIF and SDHI DT

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
conflicts.

The Allwinner A31 uses the ARM GIC as its internal interrupts controller. The
GIC can work on several interrupt triggers, and the A31 was actually setting it
up to use a rising edge as a trigger, while it was actually a level high
trigger, leading to some interrupts that would be completely ignored if the
edge was missed.

Many of the Tegra DT binding documents say nothing about the clocks or
clock-names properties, yet those are present and required in DT files.
This patch simply updates the documentation file to match the implicit
definition of the binding, based on real-world DT content.
All Tegra bindings that mention clocks are updated to have consistent
wording and formatting of the clock-related properties.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
Some omap related fixes that have come up with people moving to device
tree only based booting for omap2+.
The series contains a handful of fixes for the igep boards as they were
one of the first omap3 boards to jump over completely to device tree
based booting. So these can be considered regressions compared to
booting igep in legacy mode with board files in v3.12.
Also included are few other device tree vs legacy booting regressions:
- yet more missing omap3 .dtsi entries that have showed up booting
various boards with device tree only
- n900 eMMC device tree fix
- fixes for beagle USB EHCI
- two fixes to make omap2420 MMC work
As we're moving omap2+ to be device tree only for v3.14, I'd like to
have v3.13 work equally well for legacy based booting and device tree
based booting. So there will be likely few more device tree related
booting patches trickling in.
This series also includes a regression fix for the omap timer posted
mode that may wrongly stay on from the bootloader for some SoCs.

pin mux wl12xx_gpio and wl12xx_pins should be part of omap4_pmx_core
and not omap4_pmx_wkup. So, move wl12xx_* to omap4_pmx_core.
Fix the following error message:

pinctrl-single 4a31e040.pinmux: could not add functions for pinmux_wl12xx_pins 56x
SDIO card is not detected after moving pin mux to omap4_pmx_core since
sdmmc5_clk pull is disabled. Enable Pull up on sdmmc5_clk to detect SDIO card.
This fixes a regression where WLAN did not work after a warm reset
or after one up/down cycle that happened when we move omap4 to boot
using device tree only. For reference, the kernel bug is described at:

The r8a7790 GPIO resources are currently incorrect. Fix that
by making them match the English r8a7790 v0.6 data sheet.
Tested with GPIO LED using Lager DT reference.
This problem has been present since GPIOs were added to the r8a7790 SoC by
f98e10c88aa95bf7 ("ARM: shmobile: r8a7790: Add GPIO controller devices to
device tree") in v3.12-rc1.

Beagle (rev. C4) and Beagle-XM (all revs) need VAUX2 1.8V supply
for the USB PHY.
As the generic PHY driver can't handle more than one supply
at the moment, we configure this supply to be always on.
This will cause a very small power impact if the USB host subsystem
is not in use, about 76.86 micro-W + LDO power.
Older Beagle boards (prior to C4) don't have VAUX2 connected anywhere,
so there won't be any functional impact on those boards other than
some additional LDO power consumption.

On Device Tree boot the VDDS_DSI regulator is not linked to
the DPI device so omapfb driver probing fails with:
[ 3.186035] OMAPFB: omapfb_probe

[ 3.216735] omapfb omapfb: failed to setup omapfb
As a workaround name the VPLL2 regulator from twl4030 as vdds_dsi
so getting the VDDS_DSI regulator will succeed on dpi_init_regulator().

Most of the boards are using the TI AM/DM37x processor, there is only a small
quantity of IGEP Processor Boards based on TI OMAP3530. So it's better use the
omap36xx.dtsi include instead of omap34xx.dtsi include. We can add support
for the 34xx based variant later on as needed.
To avoid confusion we have added to the model the (TI AM/DM37x) comment.

Looks like we need to configure the regulators and use the pdata
quirk to make eMMC work with device tree.
It seems that mostly vaux3 is used, and only some earlier revisions
used vmmc2. This has been tested to work on devices where the
system_rev passed by the bootloader has versions 0x0010, 0x2101
and 0x2204.

After dropping the duplicate data in hwmod that now should come from
the .dts files, I noticed few more entries missing. Let's add these
as otherwise devices relying on these won't work.
Looks like the side tone entries are bundled into the mcbsp1 to 3,
so that may needs some special handling in the hwmod code as it's
currently trying to look up mcbsp2_sidetone and mcbsp3_sidetone
entries.

Commit 14fd8ed0a7fd19913 ("ARM: mvebu: Relocate Armada 370/XP PCIe
device tree nodes") relocated the PCIe controller DT nodes one level
up in the Device Tree, to reflect a more correct representation of the
hardware introduced by the mvebu-mbus Device Tree binding.
However, while most of the boards were properly adjusted accordingly,
the Armada 370 DB board was left unchanged, and therefore, PCIe is
seen as not enabled on this board. This patch fixes that by moving the
PCIe controller node one level-up in armada-370-db.dts.

The Armada XP provides a mechanism called "virtual CPU registers" or
"per-CPU register banking", to access the per-CPU registers of the
current CPU, without having to worry about finding on which CPU we're
running. CPU0 has its registers at 0x21800, CPU1 at 0x21900, CPU2 at
0x21A00 and CPU3 at 0x21B00. The virtual registers accessing the
current CPU registers are at 0x21000.
However, in the Device Tree node that provides the register addresses
for the coherency unit (which is responsible for ensuring coherency
between processors, and I/O coherency between processors and the
DMA-capable devices), a mistake was made: the CPU0-specific registers
were specified instead of the virtual CPU registers. This means that
the coherency barrier needed for I/O coherency was not behaving
properly when executed from a CPU different from CPU0. This patch
fixes that by using the virtual CPU registers.

Various Marvell datasheets advertise second PCIe unit of mv78230
flavour of Armada XP as x4/quad x1 capable. This second unit is in
fact only x1 capable. This patch fixes current mv78230 .dtsi to
reflect that, i.e. makes 1.0 the second interface (instead of 2.0
at the moment). This was successfully tested on a mv78230-based
ReadyNAS 2120 platform with a x1 device (FL1009 XHCI controller)
connected to this second interface.
