From e1b0d978459f17e21367fe4d3290b863919e5e73 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 28 Nov 2018 13:57:23 +0000 Subject: ARM: sa1111: remove legacy GPIO interfaces Now that we have migrated all users of the legacy private SA1111 gpio interfaces, we can remove these redundant GPIO interfaces.
