I have tested the sdmmc driver yesterday with both, CS Pin tied directly and via an external i2c port expander. TCA6408A.
Worked like charm, but today I wanted to to some further tests but I can't compile with the port expander pin as CS pin in the device tree. I only commited the devicetree for the direct pin connection but i am sure i did it like that yesterday. Maybe there is some small typo or something, maybe someone can spot the mistake.
