Re: [PATCH] arm64: zynqmp: Add pinctrl emmc description to SM-K26

po 14. 3. 2022 v 15:26 odesílatel Michal Simek michal.simek@xilinx.com napsal:

Production SOM has emmc on it and make sense to describe pin description to be able use EMMC if it is not configured via psu_init. (Still some regs are not handled but this is one step in that direction)
