Subject: MIPS: BCM47XX: Check all (32) GPIOs when looking for a pin
X-Git-Url: http://pileus.org/git/?a=commitdiff_plain;h=4fe2169acecb6e62821dfe14bc5c5852870b516f;hp=e4362d1e64ff6da64118dcf74ff450cd0a029deb;p=~andy%2Flinux

MIPS: BCM47XX: Check all (32) GPIOs when looking for a pin

Broadcom boards support 32 GPIOs and NVRAM may have entires for higher
ones too. Example:
gpio23=wombo_reset
