Why DEBUG_GPIO?

> +CONFIG_GPIO_SYSFS=y

Also, why GPIO_SYSFS?

Both of the above are nice for debugging purposes, but should not be 
enabled by default imho, as they are not needed by drivers.

I think you should not modify defconfig, rather add these as platform 
required features under arch/arm64/Kconfig.platforms?

Okay this can be left out.

This has been there for pretty much all the SoCs in the past
and one of the ways to validate GPIOs are functional. This is very much 
needed IMHO.

I observed CONFIG_RESET_TI_SCI, CONFIG_TI_SCI_PROTOCOL which are 
platform specific in the defconfig and added them here. Already there 
are n number of GPIO config options as well under defconfig. If the norm 
is to add selects under arch/arm64/Kconfig.platforms then i am fine with 
that as well. Kindly let me know.
