Dear Vikram Narayanan,
If in case this is valid according to the latest datasheet, ignore this
patch.

According to REV C manual, the register IOMUXC_IOMUXC_GPR4 has
bits 4 and 5 read-only and the value is always set as zero.
So write '0' to these bits instead of writing '1'.
I'm acking this as writing 0 to read-only bits is the only rightous thing to do.
btw. how did you find this? Good catch, praise on you :-)
:)
In the middle of writing a imximage.cfg file for a custom mx6 board.
Regards,
Vikram
