Subject: [PATCH 1/3] OMAP3 clock: split mcbspX_src_fck from mcbspX_fck
Date: Tue, 16 Sep 2008 08:18:43 -0600	[thread overview]
Message-ID: <20080916141840.13182.77302.stgit@localhost.localdomain> (raw)
In-Reply-To: <20080916141809.13182.31144.stgit@localhost.localdomain>

McBSP clock source control registers are located in the System Control
Module, not the PRCM.  However, the clock enable/disable registers are
in the CM.  Since the following patches require all registers in a
struct clk to be in only one of {CM, PRM, SCM}, we must split the
source clock selection into a separate struct clk from the clock
enable/disable control.
