From eb1ef1ed06a168cf548419ba6e99f34c8169cffe Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Mon, 17 May 2010 09:38:12 +0900 Subject: ARM: S5PV210: Register apll/mpll/epll clksrc_clk clocks This patch modifies the following. 1. Registers the mout_apll clksrc_clk clock. 2. The mout_mpll and mout_epll clocks were registered as 'struct clk' types and then their parents were setup using the s3c_set_clksrc function. This patch reduces the two steps into one by registering the mout_mpll and mout_epll clocks using the s3c_register_clksrc function. 3. As per point 2 above, the init_parents array is no longer required. So the mout clocks are now put together in a new array named 'sysclks'. The sysclks array will list the system level clocks and more clocks will be added to it in the subsequent patches. 4. The clks array is left empty because of the movement of mpll and epll clocks into the sysclks array. It is not deleted since subsequent patches will add clocks into this array.
