Another batch of fixes for ARM SoCs for 3.13. The diffstat is large,
mostly because of:
- Another set of fixes to fix regressions caused by moving OMAP from board
files to DT. Tony thinks this was the last major set of fixes, with
maybe just a few small patches to follow.
- More fixes for Marvell platforms, most dealing with misdescribed PCIe
hardware, i.e. incorrect number of busses on some SoCs, etc. The line
delta adds up due to various ranges moving around when this is fixed.
But there's also:
- Some smaller tweaks to defconfigs to make more boards bootable in my
test setup for better coverage.
- There are also a few other smaller fixes, a short series for at91, a couple
of reverts for ux500, etc.

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:

With some devices, transfer hangs during I2C frame transmission. This issue
disappears when reducing the internal frequency of the TWI IP. Even if it is
indicated that internal clock max frequency is 66MHz, it seems we have
oversampling on I2C signals making TWI believe that a transfer in progress
is done.
This fix has no impact on the I2C bus frequency.

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.

The IGEPv2 has a TFP410 DPI-to-DVI encoder attached to OMAP's
Display SubSystem (DSS).
Add mux setup for DSS pins and also for the GPIO 170 pin that
is used to ensure that the DVI-D is powered down on power up.

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.

The LBEE1USJYC is a WiFi/BT combo module used on OMAP3-based IGEP boards. In
both cases, IGEPv2 Rev. C and IGEP COM MODULE, the module is connected using
the same MMC interface and uses the same GPIOs.

Both, IGEPv2 and IGEP COM MODULE have a bus-width of 4 not 8, so fix this and

IGEP's DVI connector's DDC pins are connected to OMAP's third i2c bus.
When booting with Device Trees the requested bus number is set to -1
which means that the bus number should be dynamically assigned. So the
third i2c bus has 2 has a bus number.
Since now only DT booting is supported for IGEP boards after commit
06ff74fd ("ARM: OMAP2+: remove legacy support for IGEP boards"), the
i2c bus number has to be changed.

Enabling of Posted mode is seen to cause problems on dmtimer modules on AM33xx
(much like other OMAPs). Reference discussions on forums [1] [2]. Earlier
patch solving this on other OMAPs [3].
For OMAP SoCs with this errata, the fix has been to not enable Posted mode.
However, on some SoCs (atleast AM33xx) which carry this errata, Posted mode
is enabled on reset. So we not only need to ignore enabling of the POSTED bit
when the timer is requested, but also disable Posted mode if errata is present.

Mostly bugfixes and a few small code removals. Worth pointing out is:
- A handful of more fixes to get DT enablement working properly on OMAP,
finding new breakage of things that don't work quite right yet without
the traditional board files. I expect a bit more of this to come in this
release as people test on their hardware.
- Implementation of power_down_finish() on vexpress, to make kexec work and
to stop the MCPM core to produce a warning (the warning was new to 3.13-rc1).
- A handful of minor fixes for various platforms.
