I am okay with the older kernels not working as SOCFPGA is pretty new
and older kernel don't really have too much support for it.

Yes, the patch to update the driver was part of this series, but not
merged yet. The driver's V1 patch was Acked-By: Jamie Iles who is the
maintainer for Picoxcell and is the only other platform using this timer
driver at the moment. The only changes since V1 is to maintain
compatibility for the new binding values.
