Hello,

 

     I'm working on enabling CCM_CLKO2 clock on GPIO3 as described in iMX6 quad manual. I was told I need to enable GPIO3 in bootloader, I assume is in devicetree (.dtsi) files.

Also, I don't know where should I set the CCM_CCOSR register. In the drivers/pinctrl/pinctrl-imx6q.c file ? I see there are defined the padding.

 

    Where is the correct place to set this iomux configuration ?

 

IOMUXC_SW_MUX_CTL_PAD_GPIO03

IOMUXC_SW_PAD_CTL_PAD_GPIO03

 

Thank you,
