Maybe I just misread

that I have to explicitly specify
&mmc4 { broken-cd; } and omitting the cd-gpio is not sufficient to enable the polling mechanism...
Will try that asap.
With that addition to our DT, mmc4 is being polled. But I still get the -110 errors. I can see by scope that clock and CMD are enabled. So it is something else. Maybe pinmux.
