The Cubietruck makes use of the first three i2c controllers found on the
Allwinner A20; i2c-0 is used internally for the PMIC, i2c-1 is exposed on
the board headers, and i2c-2 is used for DDC on the VGA connector. This
patch enables them in the device tree.

The omap3_pmx_core pinmux device in the device tree handles the system
controller module (SCM) PADCONFS fonction. Its control registers are
split in two distinct areas, with other SCM registers in-between. Those
other registers can't thus be requested by other drivers as the memory
region gets reserved by the pinmux driver.
Split the omap3_pmx_core device tree node in two for the two memory
regions. The second region address and size depends on the SoC model.
The change in omap3.dtsi fixes an "external abort on non-linefetch" when
doing
cat /sys/kernel/debug/pinctrl/.../pins
on a Nokia N900.
Note that the core2 padconf region is different for 3430 vs 3630,
and does not exist on 3517 as noted by Nishanth Menon <nm@ti.com>.

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

register clocks using common clock framework") and e062b57177
("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
6e3ad26816 ("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

The BCM2835 SoC contains a DWC2 USB controller. Add this to the DT.
Set up the pin controller to fully enable the USB controller on the
Raspberry Pi. The GPIO setup works because the default output value for
GPIO 6 (LAN_RUN/n_reset) just happens to be 1, which enables the
USB/LAN chip.
Note that you'll need a U-Boot which enables power to the USB controller;
search for U-Boot patch "ARM: rpi_b: power on SDHCI and USB HW modules".
