Merge most of tag 'tags/exynos-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git into next/dt 

From Kukjin Kim, these are device-tree updates for Exynos. Among the changes:
- add MIPI PHY node for exynos4
- update regulator for origen and exynos5250-arndale
- add support HDMI for exynos5250, exynos5420

* commit '93457b9cb980ffeeef020c3bcd99065c3807619b':
  ARM: dts: Add HDMI related I2C nodes for Arndale board
  ARM: dts: enable hdmi subsystem for exynos5420 smdk board
  ARM: dts: add dt nodes for hdmi subsystem for exynos5420
  ARM: dts: add i2c device nodes for Exynos5420
  ARM: dts: add clocks to hdmi dt node for exynos5250
  ARM: dts: add mixer clocks to mixer node for Exynos5250
  of/documentation: update with clock information for exynos hdmi subsystem
  ARM: dts: Disable Exynos5250 I2S controllers by default
  ARM: dts: Add reg property to regulator nodes in exynos5250-arndale
  ARM: dts: Add fixed voltage regulator to simple bus for origen
  ARM: dts: Add MIPI PHY node to exynos4.dtsi

a) phandle of the gpio controller node.
b) pin number within the gpio controller.
c) optional flags and pull up/down.
- clocks: list of clock IDs from SoC clock driver.
a) hdmi: Gate of HDMI IP bus clock.
b) sclk_hdmi: Gate of HDMI special clock.
c) sclk_pixel: Pixel special clock, one of the two possible inputs of
HDMI clock mux.
d) sclk_hdmiphy: HDMI PHY clock output, one of two possible inputs of
HDMI clock mux.
e) mout_hdmi: It is required by the driver to switch between the 2
parents i.e. sclk_pixel and sclk_hdmiphy. If hdmiphy is stable
after configuration, parent is set to sclk_hdmiphy else
sclk_pixel.
- clock-names: aliases as per driver requirements for above clock IDs:
"hdmi", "sclk_hdmi", "sclk_pixel", "sclk_hdmiphy" and "mout_hdmi".
