Subject: GPIO: omap_gpio: Fix gpio name names with device tree
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-logo.png?a=commitdiff_plain;h=535f46dad920094df12b2d19f071db2e6a8ae0ab;p=u-boot.git

GPIO: omap_gpio: Fix gpio name names with device tree

The GPIO bank numbers do not appear in the device tree, so this
patch makes the gpio name based on the address
(ie gpio@49054000_31 vs gpio4_31)
