Setting up external oscillator to SSI

Hi All,

 

I'm setting up a custom board providing an external oscillator for the SSI to control an audio device, the oscillator provide 2.048KHz clock to SSI but the SSI as to generate the frame sync for the TDM. I've setup both SSI and AUDMUX accordingly but I guess there is also the PLL4 clock side to set, see in http://cache.freescale.com/files/32bit/doc/app_note/AN4952.pdf.

I'm not really sure how to do it in the kernel file clk-imx6sx.c, does anyone can help here and suggest the related changes?

 

Thanks in advance,

Roberto Fichera.
