[PATCH v2 0/2] AM64: Add support for GPIO
The following series of patches adds support for gpio on AM642 evm/sk. Changes since v1: - Added DT for gpio subsystem present in MCU domain - reserved the mcu gpio for firmware usage This series of patches depend on, https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=439039 https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=439153 Aswath Govindraju (2): arm64: dts: ti: k3-am64: Add GPIO DT nodes arm64: dts: ti: k3-am642: reserve gpio in mcu domain for firmware usage arch/arm64/boot/dts/ti/k3-am64-main.dtsi | 45 arch/arm64/boot/dts/ti/k3-am64-mcu.dtsi | 27 ++ arch/arm64/boot/dts/ti/k3-am642-evm.dts | 5 +++ arch/arm64/boot/dts/ti/k3-am642-sk.dts | 5 +++ 4 files changed, 82 insertions(+) -- 2.17.1
