The rootfs is mounted on mmc1 and works as usual. Here is what I can see: - pbias-supply is parsed from DT - VMMC1 is set to 3V - According to the debugfs entry, we are working at 3V signaling - By dumping CONTROL_PBIASLITE, bit MMC1_PBIASLITE_VMODE (PBIASLITEVMODE0 on OMAP3) is set to 1 (-> 3V) Do you see any other tests that I could run to validate your patches?
