Subject: sh: pfc: Dumb GPIO stringification.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=72c7afa10f272710028f244da65d35e571144085;p=linux-beck.git

sh: pfc: Dumb GPIO stringification.

This implements fairly simplistic stringification of existing pinmux
GPIOs for easy enum id -> string mapping, which will subsequently be used
by the pinctrl support code.
