Subject: [PATCH 01/10] OMAP3 clock: remove wait for DPLL3 M2 clock to stabilize
Date: Tue, 26 May 2009 16:12:28 -0600 [thread overview]
Message-ID: <20090526221226.25381.8156.stgit@localhost.localdomain> (raw)
In-Reply-To: <20090526220517.25381.75976.stgit@localhost.localdomain>
The original CDP kernel that this code comes from waited for 0x800
loops after switching the CORE DPLL M2 divider. This does not appear
to be necessary.
