So, can you please have these patches in your queue ? I'll soon post the test results indicating the functioning of GPIOs. Thanks, Aswath

Thanks in advance for digging into this and detailed testing.

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(+)
