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

Based 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.

I've posted a respin(v3) of this series after rebasing on top of
ti-k3-dts-next branch and adding the GPIO test logs.

Thanks,
Aswath
