Subject: [PATCH 06/13] OMAP clock: compress clock flags down to a u8
Date: Thu, 11 Feb 2010 11:17:03 -0700 [thread overview]
Message-ID: <20100211181701.795.87996.stgit@localhost.localdomain> (raw)
In-Reply-To: <20100211181236.795.56094.stgit@localhost.localdomain>
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.
