Fixed regulator is used for SDHI0/2 Vcc.
We should use da9063 driver for Vccq,
but, it doesn't have regulator support at this point.
This patch uses gpio-regulator for it as quick-hack.

In R-Car GPIO hardware block, 'chattering removal' feature can be
enabled on GPIO-n-[3:0] pins, but it's not supported on rest of pins
GPIO-n-[31:4].
Set an appropriate debounce interval, instead. We could confirm that
spurious/unnecessary GPIO interrupts are prevented by this settings.

Do not build the phy fixup unless CONFIG_PHYLIB is enabled.
Other than not being useful it is also not possible to link
the code under this condition as phy_register_fixup_for_id(),
mdiobus_read() and mdiobus_write() are absent.

Board-related updates. This branch is getting smaller and smaller, which is
the whole idea so that's reassuring.
Right now by far most of the code is related to shmobile updates, and
they are now switching over to removal of board code and migration to
multiplatform, so we'll see their board code base shrink in the near
future too, I hope.
In addition to that is some defconfig updates, some display updates for OMAP
and a bit of new board support for Rockchip boards.

Add r8a7790 SMP support using the shared APMU code. To enable
SMP the r8a7790 specific DTS needs to be updated to include
CPU cores, and this is happening in a separate patch.

MMCIF on r8a7790 doesn't support Command Completion Signal, but it does
implement a CE_CLK_CTRL2 register. Platform parameters have to be added to
account for these features on lager.

Currently on the Lager board NFS timeouts/delays are seen when booting. That
turned out to happen because the SoC's ETH_LINK signal turns on and off after
each packet. It is connected to Micrel KSZ8041 PHY's LED0 signal. Ether LEDs
on the Lager board are named LINK and ACTIVE which corresponds to non-default
01 setting of the PHY control register 1 bits 14-15. The 'sh_eth' driver resets
the PHY when opening the network device, so we have to set the mentioned bits
back to 01 from the default 00 value which causes bouncing of ETH_LINK. That
can be achieved using the PHY platform fixup mechanism if we also modify the
driver to use it..

Board updates for 3.12. Again, a bit of domain overlap with SoC and DT branches,
but most of this is around legacy code and board support. We've found that
platform maintainers have a hard time separating all of these out and might
move towards fewer branches for next release.
- Removal of a number of Marvell Kirkwood board files, since contents
is now common and mostly configured via DT.
- Device-tree updates for Marvell Dove, including irqchip and clocksource
setup.
- Defconfig updates. Gotta go somewhere. One new one for Renesas Lager.
- New backlight drivers for backlights used on Renesas shmobile platforms.
- Removal of Renesas leds driver.

When the gpio-keys device is registered using
platform_device_register_data() the platform data argument,
lager_keys_pdata is duplicated and thus should be marked as __initdata
to avoid wasting memory. However, this is not true of gpio_buttons,
a reference to it rather than its value is duplicated when lager_keys_pdata
is duplicated.
This avoids accessing freed memory if gpio-key events occur
after unused kernel memory is freed late in the kernel's boot.
This but was added when support for gpio-keys was added to lager
in c3842e4fcb
("ARM: shmobile: lager: support GPIO switches") which was included
in v3.11-rc1.
