Please instead add:

This file documents differences between the core properties described
by mmc.txt and the properties used by the dw_mmc driver.

mmc.txt already describes compatible, reg, interrupts, bus-width,
cd-gpios, and wp-gpios, so you don't need to describe those again.

of_quirks, not of_quriks.

Thanks,
