From e5bb79e897a95b688a93087f04848a043782a6a7 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Thu, 8 Mar 2012 11:22:03 +0100 Subject: [PATCH 26/70] MIPS: lantiq: convert falcon gpio to clkdev api The falcon gpio clocks used to be enabled when registering the platform device. Move this code into the driver and use clkdev api.
