Hi Sir:
There is an problem confusing me very much that could i set the rts_gpio's value, used in omap_serial.c for the rs485 communication , the address of the any gpio that could access? if it could,how should i configure it in the device tree.
Or it just should the three pin-mux pins,rts,rx,tx ,be set, and then the driver will set the rts_gpio's value itself?
your answer is appreciated very much!
