Merge tag 'samsung-dt-pinctrl-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/dt
Pull "Topic branch for Samsung DeviceTree cleanup for 4.9" from Krzysztof Kozłowski: Replace in DT sources hard-coded values for pinctrl configuration like pull up/down, drive strength and function. This makes the DTS easier to read, especially that some drive strengths values are quite non-obvious. * tag 'samsung-dt-pinctrl-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: ARM: dts: s3c64xx: Use macros for pinctrl configuration ARM: dts: s3c2416: Use macros for pinctrl configuration ARM: dts: s5pv210: Use macros for pinctrl configuration ARM: dts: s3c64xx: Use common macros for pinctrl configuration ARM: dts: exynos: Fix mismatched values of SD drive strengh configuration on exynos4415 ARM: dts: exynos: Fix mismatched value for SD4 pull up/down configuration on exynos4210 ARM: dts: exynos: Use macros for pinctrl configuration on exynos542x/exynos5800 ARM: dts: exynos: Use macros for pinctrl configuration on exynos5410 ARM: dts: exynos: Use macros for pinctrl configuration on exynos5260 ARM: dts: exynos: Use macros for pinctrl configuration on exynos5250 ARM: dts: exynos: Use macros for pinctrl configuration on exynos4415 ARM: dts: exynos: Use macros for pinctrl configuration on exynos4x12 ARM: dts: exynos: Use macros for pinctrl configuration on exynos4210 ARM: dts: exynos: Use macros for pinctrl configuration on exynos3250 ARM: dts: exynos: Use common macros for pinctrl configuration pinctrl: dt-bindings: samsung: Update documentation with new macros pinctrl: dt-bindings: samsung: Add header with values used for configuration
