I had to come up with a fix for this exact problem a week or so ago,
and I went a little bit further than this patch and ported Linux clock
code for i.MX51/53 which already has code to create a clock provider.
I'll post the series shortly and we can compare notes and pick a way
to go forward. I am obviously biased toward having the same (almost)
code as Linux does, but this patch is less invasive, so I'll be happy
to pick it up if that's the direction we decide to go.
Thanks,
