Allwinner A13 mmc2 Issues: fatal err update clk timeout

[cooke...@gmail.com]

I'm trying to enable the mmc2 Peripheral on the A13 to get a second SD Card working.

After enabling it in the Devicetree and starting the A13 my console is spammed with this error: sunxi-mmc 1c11000.mmc: fatal err update clk timeout

I checked if the mmc Pins are shorted against each other and also against VCC and GND, so electrical everything should be fine. This error message also appears if no SD Card is present.

I'm running the latest 6.2-3 Mainline Kernel .
