From f71eddb1582f5c53ed4bfc365a2acce94aca88cc Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Mon, 22 Feb 2010 22:09:18 -0700 Subject: [PATCH] OMAP clock: compress clock flags down to a u8 There are now only eight OMAP clock flags, so renumber the flags to fit in a u8 and shrink the size of struct clk.flags from a u32 to a u8. The intention is to save memory.
