device_node_to_regmap() is exactly like syscon_node_to_regmap(), but it
does not check that the node is compatible with "syscon", and won't
attach the first clock it finds to the regmap.

The rationale behind this, is that one device node with a standard
compatible string "foo,bar" can be covered by multiple drivers sharing a
regmap, or by a single driver doing all the job without a regmap, but
these are implementation details which shouldn't reflect on the
devicetree.

Does this looks like a good path forwards to you? Its use in this case
is described by Documentation/devicetree/bindings/timer/ingenic,tcu.txt
in patch 3 of the series.

If you're OK with it an ack would be appreciated so I can take the
series through mips-next, otherwise I guess we'd need to go back to the
v14 approach.

Yes, I guess this is ok, sorry for missing the submission earlier.
