MMC1 data line IO's are powered down in before set regulator function. IO's should not be powered ON when regulator is OFF. Keep the IO's in power pown mode after regulator OFF. Delete incorrect comments which are not applicable for OMAP4.Care to check how this is different from what I added into fixes branch as commit 3fe8df93b0992199e3a0026fc51e90b705f94e40? Is this a separate issue?Yes. commit 3fe8df93b fixes USBC1 configuration. USBC1 IO was configured unnecessarily for MMC IO. This patch keeps the MMC IO's in power down after regulator OFF otherwise it generates VMODE_ERROR due to mismatch in input (regulator) voltage and MMC IO drive voltage.
OK, can you please refresh it against the current fixes branch? Thanks, Tony
