This patchset adds initial pinctrl support for Mediatek MT6797 SoC. The pinctrl driver is based on the vendor binding as like MT6765 and implements only GPIO and pinmux functionalities. The devicetree binding document consists of pinmux, pinconf and interrupt functionalities documented since the binding should describe what the hardware is capable of rather than what the driver offers. This patchset has been tested on 96Boards MediatekX20 development board. Thanks, Mani Changes in v3: * Modified bindings doc according to Sean's suggestion. Changes in v2: * Added devicetree bindings for Pin Controller * Dropped the applied warning fix patch * Added Tested-by tag from Matthias Brugger * Added Acked-by tag from Sean Wang Manivannan Sadhasivam (4): dt-bindings: pinctrl: Add devicetree bindings for MT6797 SoC Pinctrl arm64: dts: mediatek: mt6797: Add pinctrl support arm64: dts: mediatek: x20: Add pinmux support for UART1 pinctrl: mediatek: Add initial pinctrl driver for MT6797 SoC .../bindings/pinctrl/pinctrl-mt6797.txt | 83 + .../boot/dts/mediatek/mt6797-x20-dev.dts | 2 + arch/arm64/boot/dts/mediatek/mt6797.dtsi | 21 + drivers/pinctrl/mediatek/Kconfig | 7 + drivers/pinctrl/mediatek/Makefile | 1 + drivers/pinctrl/mediatek/pinctrl-mt6797.c | 82 + drivers/pinctrl/mediatek/pinctrl-mtk-mt6797.h | 2430 +++++++++++++++++ include/dt-bindings/pinctrl/mt6797-pinfunc.h | 1368 ++++++++++ 8 files changed, 3994 insertions(+) create mode 100644 Documentation/devicetree/bindings/pinctrl/pinctrl-mt6797.txt create mode 100644 drivers/pinctrl/mediatek/pinctrl-mt6797.c create mode 100644 drivers/pinctrl/mediatek/pinctrl-mtk-mt6797.h create mode 100644 include/dt-bindings/pinctrl/mt6797-pinfunc.h -- 2.17.1
