From f689332b19fa1120de1bd84988a7bd0c08bd9b7b Mon Sep 17 00:00:00 2001 From: Alban Bedel Date: Fri, 3 Jul 2015 11:11:48 +0200 Subject: [PATCH] MIPS: Ath79: Remove the unused GPIO function API To prepare moving the GPIO driver to drivers/gpio remove the platform specific pinmux API. As it is not used by any board, and such functionality should better be implemented using the pinmux subsystem just removing it seems to be the best option.
