Change frequency of CKO(GPIO_0)

[hyunhoshin]

I'm using GPIO_0(CCM_CLKO1) for MCLK of Audio CODEC

It's frequency is 24Mhz,

but, I need 12Mhz for Audio CODEC.

How can i change that frequency?

I'm using N7.1.1.1.0.0-ga and i.MX6D

thank you.

Hi  hyunho

one can follow AN4952 i.MX 6 Audio Clock Configuration Options

https://www.nxp.com/docs/en/application-note/AN4952.pdf 

and look at example

[4/4] ARM: imx6q: remove board specific CLKO setup - Patchwork
