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
