DT changes continue to be the bulk of our merge window contents.
We continue to have a large set of changes across the board as new platforms
and drivers are added.
Some of the new platforms are:
- Alphascale ASM9260
- Marvell Armada 388
- CSR Atlas7
- TI Davinci DM816x
- Hisilicon HiP01
- ST STiH418
There have also been some sweeping changes, including relicensing of DTS
contents from GPL to GPLv2+/X11 so that the same files can be reused in
other non-GPL projects more easily. There's also been changes to the
DT Makefile to make it a little less conflict-ridden and churny down
the road.

Clock related properties are added to the Exynos4 I2S device nodes
so they can be referred to as clock providers. Missing i2s_opclk1
clock is added to the I2S0 node and clock properties are added
to the MAX98090 codec node to allow it to control/read frequency
of the MCLK clock directly.

This ensures the core and the audio subsystem clocks are configured

Specify the default mux and divider clocks in device tree
to ensure the FIMC devices on Trats, Trats2, Universal_c210
and Odroid X2/U3 boards are clocked from recommended clock
source and with maximum supported frequency.
For Trats2 also the MIPI-CSIS and the camera sensor clocks
are configured, the 'clock-frequency' property is deprecated
in favour of 'assigned-clock-rates' property.

dw-mmc controller can support multiple slots.
But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
"supports-highspeed" property can be replaced with "cap-sd/mmc-highspeed".

Increase max i2c bus frequency beyond the default for faster
data transfers. According to the manual, these faster speeds are
only available when the board is wired up the right way. In this case,
the vendor kernel has run at this speed for a long time.
sda-delay is needed for talking to RTC on PMIC, otherwise the i2c
controller never sees an ACK. Strangely the other PMIC i2c slave (the
main one) works fine even without this delay. I Chose value 100 to
match the vendor kernel.

This patch moves some parts of exynos4412-odroidx.dts to common
exynos4412-odroid-common.dtsi file and adds support for Odroid X2 and
U2/U3 boards. X2 is same as X, but it has faster SoC module (1.7GHz
instead of 1.4GHz), while U2/U3 differs from X2 by different way of
routing signals to host USB hub. It also lacks some hw modules not yet
supported by those dts files (i.e. LCD & touch panel).
