Why don't working connect ccm with MX6QDL_PAD_NANDF_CS2__CCM_CLKO2 pin throught iomux

[ignat]

Hi all!

 My task connect my audiocodec with i2s clocks on custom board.  I changed alternative for that pin in imx6qdl-sabresd.dtsi :

&iomuxc {
   pinctrl-names = "default";   
   pinctrl-0 = <&pinctrl_hog>;

   imx6qdl-sabresd {
   pinctrl_hog: hoggrp {
   fsl,pins = <
   MX6QDL_PAD_NANDF_CS2__CCM_CLKO2 0x130b0

   ...

   >

But i'm  not get output on that pin ( i checked output with oscilloscope) . 

Maybe i must connect iomucx  in dts file with clks? How? 

Maybe i must configure u-Boot ? How? 

Maybe i must use iomux_tool.exe ? How? ( C files from genereted code not сompitable with linux kernel )

Thanks

Best regards

Hi Ignat

for CLKO2 example one can look on

imx6sx-nitrogen6sx.dts\dts\boot\arm\arch - linux-imx - i.MX Linux kernel 

also it can be configured in uboot

Best regards
