The GPIOs and pin controller registers have mapping and holes in the map. These have been extracted from the AM62P data sheet. MCU pinctrl definition is shared as it is common between AM62P and J722S, but that is not the case for main domain. Ref: AM62P Data sheet https://www.ti.com/lit/gpn/am62p Signed-off-by: Nishanth Menon --- Changes since V1: - Use PIN_GPIO_RANGE_IOPAD instead of PIN_GPIO_MUX_MODE - Refactored on top of next-20240626 (new common files) - Since the patch had to be refactored as well as new define used, I have skipped picking up Dhruva's Reviewed-by.
