Merge branch 'next/dt-samsung' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/dt
From Kukjin Kim: Here is Samsung DT for v3.8 and this is including DT for EXYNOS4X12 SoC, SMDK4412 board, pinctrl for exynos4x12, TMU, MFC, SATA and SATA PHY. As I commented on [4/7], this branch merged pinctrl/samsung to support pinctrl for exynos4x12 without useless merge conflicts. * 'next/dt-samsung' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: (32 commits) ARM: EXYNOS: DT Support for SATA and SATA PHY ARM: dts: Remove broken-voltage property from sdhci node for exynos4210-trats ARM: dts: Add node for touchscreen for exynos4210-trats ARM: dts: Add node for touchscreen voltage regulator for exynos4210-trats ARM: dts: Add node for i2c3 bus for exynos4210-trats ARM: dts: Add nodes for GPIO keys available on Trats ARM: dts: Update for pinctrl-samsung driver for exynos4210-trats ARM: dts: Add nodes for pin controllers for exynos4x12 pinctrl: samsung: Add support for EXYNOS4X12 gpio: samsung: Skip registration if pinctrl driver is present on EXYNOS4X12 ARM: EXYNOS: Skip wakeup-int setup if pinctrl driver is used on EXYNOS4X12 ARM: dts: add board dts file for EXYNOS4412 based SMDK board ARM: dts: Add support for EXYNOS4X12 SoCs ARM: EXYNOS: Add devicetree node for TMU driver for exynos5 ARM: EXYNOS: Add devicetree node for TMU driver for exynos4 ARM: EXYNOS: Add MFC device tree support ARM: dts: Enable serial controllers on Origen and SMDKV310 Documentation: Update samsung-pinctrl device tree bindings documentation pinctrl: samsung: Add GPIO to IRQ translation pinctrl: exynos: Set pin function to EINT in irq_set_type of wake-up EINT ...
