in 3.10.53 kernel:

 

CCM_CLKO1(audio i2s master)is 24MHZ ,   how to set to 11.2896MHzMHz

 

 

I change

imx_clk_set_rate(clk[pll4_audio_div], 541900800);

to

imx_clk_set_rate(clk[pll4_audio_div], 90316800); //8*11289600

 

question:

clk_get_rate(data->codec_clk) print the value is 11289600,

but the clock is still 22.5MHZ(11289600*2) by  oscilloscope
