From 23ff3d8aa7230767184847e89ba91abd8bdb561d Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Tue, 4 Jun 2013 12:25:37 -0700 Subject: [PATCH] ARM: msm: Make proc_comm clock control into a platform driver To move closer to the generic struct clock framework move the proc_comm based clock code to a platform driver. The data describing the struct clks still live in the devices-$ARCH file, but the clock initialization is done at driver binding time.
