I have a custom board with IMX6Q and SGTL5000, using linux 3.10.17.

 

I have configure GPIO_19 as CCM_CKO1 in dtsi file. The 24MHz waverform starts and dead just one second after. This seams as if anyone reconfigured the pin, but in DTS there isn´t anyone changing it.

 

Are there some know issue of use CCM_CKO1 in GPIO_19 pin?
