Thanks Matt,
I think Anil labeled it as gpio1-4 due to hwmod naming convention, as you
can not have gpioo id = 0 (refer to arch/arm/mach-omap2/gpio.c).
But in case of DT we should simply follow TRM/Spec, as naming convention is
based on base-addr and not id, so your patch looks good me.
Thanks,
Vaibhav
