Commit Message

Yixun Lan Nov. 30, 2025, 9:45 p.m. UTC

Introduce pinctrl driver for A733 SoC, but only limited devices are
supported which includes GMAC, MMC, SPI, UART.

Setup an offset 0x80 for virtual PA port, as A733 changes the register
layout, with this adjustment, all other ports can be found correctly.
