In the parent thread, I understood that I need to implement "$u-boot/board/ti/am335x/mux.c" for our target board.
Though I know that there are many documents for how to implement device tree, I don't know any implementation guide for U-boot's mux.c.
After seeing mux.c, I understand a little how to implement mux.c, and probably implement mux.c without implementation guide. But, if getting implementation guide, I will be able to implement it accurately. Is there any implementation guide for mux.c ?
