The Beagleboard-xM has a LAN9514 USB hub and ethernet controller,
connected to port 2 of the OMAP EHCI controller. The board however has
no EEPROM to store the ethernet MAC address, which is programmed by the
boot loader.
To allow Linux to use the same MAC address as the boot loader (or for
that matter any fixed MAC address), we need a node in the device tree
for the ethernet controller that the boot loader can update at runtime
with a local-mac-address property. Add it, along with an alias for the
ethernet controller to let the boot loader locate it easily.

As always, this tends to be one of our bigger branches. There are lots of
updates this release, but not that many jumps out as something that needs
more detailed coverage. Some of the highlights are:
- DTs for the new Annapurna Labs Alpine platform
- More graphics DT pieces falling into place on Exynos, bridges, clocks.
- Plenty of DT updates for Qualcomm platforms for various IP blocks
- Some churn on Tegra due to switch-over to tool-generated pinctrl data
- Misc fixes and updates for Atmel at91 platforms
- Various DT updates to add IP block support on Broadcom's Cygnus platforms
- More updates for Renesas platforms as DT support is added for various IP
blocks (IPMMU, display, audio, etc).

N900 now seems to shut down the external oscillator when hitting
off-idle.
And Beagle XM seems to have OSC_EN pin connected to allow shutting
down the oscillator looking at the schematics. The oscillator
output is cut off in off-idle and you can monitor it from R56 on
the bottom side of the board near the power jack. Note that for
beagle we need to also enable the UART wake-up event, the others
have that enabled in earlier patches.
OMAP37XX EVM (TMDSEVM3730) does not seem to have twl4030 clken
pin connected, so there is no point trying to enable shutting
down of the oscillator on it for the extra latency it adds.

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>.

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.

NOTE: This currently will use I2C1 bus communication path to set the

continue to use twl-common.c which bypasses I2C1 bus communication path
and uses I2C4 bus path using OMAP voltage libraries. We should
