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(+) -- 2.17.1Based on your offline comment: ----- On going through the bootlogs before posting for I found the following errors, [ 1.091117] davinci_gpio 601000.gpio: IRQ index 2 not found [ 1.101522] davinci_gpio 601000.gpio: error -ENXIO: IRQ not populated Some issues in allocating interrupts in case of main_gpio1. I accumulated the gpio with interrupt numbers. I'll try to debug the reason behind it and update you with its status. (bootlogs of ti-sdk, also have this error). ----- I am going to drop this off my queue, please update if the fixup is some system configuration error or repost with fix.This is expected to be a fixup in the system configuration and not a bug in the patch series. So, can you please have these patches in your queue ? I'll soon post the test results indicating the functioning of GPIOs.
Thanks for clarifying. I will wait till the test results are posted. Thanks in advance for digging into this and detailed testing. -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
