MMC clock pins must be configured as OUTPUT-only per TRM specification [0]
with receiver disabled (RXACTIVE bit = 0). Change MMC1_CLK from PIN_INPUT
to PIN_OUTPUT in AM64 device trees to match documentation.
There was an issue showing up in automated testing that I was not sure
if it was attributed to this patch series. So I was waiting to see the
error again to debug. Not 100% confident this should go upstream yet.
