Subject: gpio: mxc_gpio: change gpio index for i.MX8
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e168eacde1cfbdcf75e92bfda6d51fa59d488dfd;p=oweals%2Fu-boot.git

gpio: mxc_gpio: change gpio index for i.MX8

Since the i.MX8 GPIO banks are indexed from 0 not 1 on other i.MX
platforms, so we have to adjust the index accordingly.
