Ok, then it is the distro that have to take care about that. For the time being I'll manually force pinctrl-cherryview in the initrd. However, while the Acer Aspire R11 sd card reader works, the one in the compute stick STK1AW32SC doesn't. Every time I insert a sd card I see this message in the journal: mmc1: error -84 whilst initialising SD card Tested with kernel 4.8rc7. Where can I get help about that?
