On certain i.MX8 series parts [1], the PPS channel 0 is routed internally to eDMA, and the external PPS pin is available on channel 1. In addition, on certain boards, the PPS may be wired on the PCB to an EVENTOUTn pin other than 0. On these systems it is necessary that the PPS channel be able to be configured from the Device Tree.

We can't take patches only for older stable kernels, and not newer ones for obvious reasons (i.e. you will upgrade and have a regression.) So please provide backports for all active kernels and we will be glad to review them then.
thanks,
