Hi, that patch subject is utterly wrong. the real desc would be
"add support for the 2nd CS line on mt7620a and add a special device_id for this." however, as you only register the CS with the spi driver and are missing the actuall /cs1 mux init, this patch is wrong/incomplete as it relies on the bootloader to have setup the cs line already and has a misleading desription.
