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
