Subject: [PATCH V2 0/2] About i.MX GPT input capture patches

The backgroud of this upstream is: I used to enable i.MX GPT input
capture function for i.MX8MM. And I found patches following from Steve:
https://lore.kernel.org/linux-arm-kernel/20191016010544.14561-2-slongerbeam@gmail.com/
https://lore.kernel.org/linux-arm-kernel/20191016010544.14561-3-slongerbeam@gmail.com/
After applied the patches and do some modification, GPT input capture
function was enabled in i.MX8MM. When checked in latest BSP, seems the
two patches are not included. I am not sure about the upstream status
initiated by Steve. So as a latercomer, I am doing this upsteam again.

V2:
 - delete the patch for i.MX8MM example in yaml file because of lots of
   warnings due to chips missing, will add to it later
