From 8c725dcd2246e8500a6fdd394ef4cb0cf96f2217 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Sun, 16 Sep 2012 10:45:54 -0600 Subject: ARM: OMAP2+: clock: add OMAP CCF convenience macros to mach-omap2/clock.h Define four convenience macros to be used in the upcoming OMAP2+ common clock framework port. Although the use of these macros will make the data somewhat more difficult to read, they significantly reduce the number of lines in the output patch data. Most of these were created by Rajendra Nayak and Mike Turquette, as far as I know.
