Hi Vladimir ,

With this the rate wouldn't get initialised and it throws a warning at
boot.

Will be fixed with this change below :

-		CLOCK_CLKSEL0(sgx_clk_mux_sel,
+		CLOCK_CLKSEL_INIT(sgx_clk_mux_sel,

May be CLOCK_CLKSEL0 is not required altogether. I see it used only to
initialise gpu_fck. May be can remove this.

I boot tested it on 4430 sdp. FWIW , you can add
