I am running the freescale 4.1 2.0.0 GA release of linux on the imx7d sabre board. I would like to configure the pad GPIO1_IO02 to output from CCM_CLKO1. (This is indicated as possible via section 5.2.2 of the i.mx7 reference manual). However, looking at imx7d-pinfunc.h, I don't see a pinmux setting corresponding to my desired configuration. Is there a reason for this omission? Is that pin used for something else, or is that clock not usable in linux?
Thanks for any pointers!
