This is in fact what I am currently pursuing. I decided to go for the dts solution, so I looked at drivers/pinctrl/pinctrl-zynq.c in order to figure out how to route the i2c pins to the PL via EMIO. What I found was that the driver apparently does not support this for devices other than sd/sdio controller units, so I guess I would have to extend it to make this work, am I right? regards, Thomas -- _______________________________________________ meta-xilinx mailing list [email protected] https://lists.yoctoproject.org/listinfo/meta-xilinx
