[PATCH DNI v3 00/15] media: rcar-fcp, vsp1: Enable on R-Car X5H

[Paul Elder]

This series is based on Geert's
"topic/rcar-x5h-ironhide-scmi-cpg-mdlc-remapping-v3" branch [0]. A
branch including this series is available here [1].

This series enables the FCPV{B,I,D} and the VSP{B,I,D} blocks on the Renesas
R-Car X5H SoC.

This has been tested on an Ironhide with the vsp-tests test suite [2].

The first couple patches add clocks that are used by the FCP and VSP,
but as the upstream X5H CPG driver is barebones at the moment and we
don't yet ensure that the parents are enabled, these are marked as DNI
for the moment.

The last patch checks the device revision and prints it, which is useful
for debugging but is unnecessary processing for driver operation so it
is marked as DNI as well.

In v3, most of the patches have become DNI because they depend on wip
cpg and mdlc driver work. The non-DNI patches are targets for immediate
upstreaming though.

There was some odd behavior with the clocks, where from what I
understood was that the clocks for the FCPV{B,I} and VSP{B,I} are
always-on, but the tests would hang unless I explicitly enabled...  the
always-on clock (or fsleep). Then after I removed the patch that
explicitly enabled the always-on clock everything ran fine. Just
reporting that this happened just in case it's relevant.
