2016-09-19Merge tag 'samsung-dt-pinctrl-4.9' of ↵Arnd Bergmann
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
2016-09-16ARM: dts: exynos: Use macros for pinctrl configuration on exynos4210Krzysztof Kozlowski
Usage of DTS macros instead of hard-coded numbers makes code easier to read. One does not have to remember which value means pull-up/down or specific driver strength.

2016-09-01ARM: dts: exynos: Add missing unit name to memory nodes in Exynos4 DTSJavier Martinez Canillas

2016-09-01ARM: dts: exynos: Remove skeleton.dtsi usage for Exynos4Javier Martinez Canillas
The skeleton.dtsi file was removed in ARM64 for different reasons as explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi"). These also applies to ARM and it will also allow to get rid of the following DTC warnings in the future: "Node /memory has a reg or ranges property, but no unit name" The disassembled DTB are almost the same besides an empty chosen node being removed and nodes reordered, so it should not have functional changes.

2016-06-08ARM: dts: exynos: enable MFC device for all boardsMarek Szyprowski
MFC device can be used without any external hardware dependencies (when IOMMU is enabled), so it can be enabled by default (like it has been already done for Exynos 542x platforms). This unifies handling of this device for Exynos3250, Exynos4 and Exynos542x platforms. Board can still include exynos-mfc-reserved-memory.dtsi to enable using this device without IOMMU being enabled.

2016-01-29ARM: dts: Replace legacy *,wakeup property with wakeup-source for exynos boardsSudeep Holla
Though the keyboard and other driver will continue to support the legacy "gpio-key,wakeup", "linux-keypad,wakeup" boolean property to enable the wakeup source, "wakeup-source" is the new standard binding. This patch replaces all the legacy wakeup properties with the unified "wakeup-source" property in order to avoid any further copy-paste duplication.

2012-09-21ARM: dts: Assume status of all optional nodes as disabled for exynos4Tomasz Figa
Currently all boards must explicitly disable all unused device tree nodes of unused components (e.g. i2c, sdhci, etc...). This makes it necessary to all boards to be aware of all components on the SoC, which in turns makes board dts files longer and more difficult to maintain (e.g. adding new components to SoC-level tree requires adding nodes with status="disabled" to every board). This patch changes "status" of all optional components in SoC-level dts file to "disabled", adds status="okay" to respective nodes of used components in dts of all boards and removes all nodes with only status="disabled" from boards dts.
