I missed when I first reviewed this patch but there is no need to
enclose the padconf values into parenthesis, for example the following
is easier to read and is preferred IMHO:
AM33XX_IOPAD(0x9b0, PIN_OUTPUT_PULLDOWN | MUX_MODE3) /* xdma_event_intr0 */
Same for all the other pinctrl lines.
Best regards,
