Currently ssi driver only supports slave mode and thus need only to handle the ipg clock, because the peripheral clock comes from the master codec. Only register the ipg clock and do not register the peripheral clock for ssi Signed-off-by: Fabio Estevam --- arch/arm/mach-imx/clk-imx27.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/arch/arm/mach-imx/clk-imx27.c b/arch/arm/mach-imx/clk-imx27.c index 1ffe3b534..303d7bd 100644 --- a/arch/arm/mach-imx/clk-imx27.c +++ b/arch/arm/mach-imx/clk-imx27.c @@ -274,8 +274,6 @@ int __init mx27_clocks_init(unsigned long fref) clk_register_clkdev(clk[scc_ipg_gate], "scc", NULL); clk_register_clkdev(clk[cpu_div], "cpu", NULL); clk_register_clkdev(clk[emi_ahb_gate], "emi_ahb" , NULL); - clk_register_clkdev(clk[ssi1_baud_gate], "bitrate" , "imx-ssi.0"); - clk_register_clkdev(clk[ssi2_baud_gate], "bitrate" , "imx-ssi.1"); mxc_timer_init(MX27_IO_ADDRESS(MX27_GPT1_BASE_ADDR), MX27_INT_GPT1);
