This patch adds support to add child devices to gcc as some of the
registers mapped by gcc are used by drivers like thermal sensors.

How about calling of_syscon_register() instead? That would give us a
handle to a regmap that can be consumed in e.g. the thermal driver.
Two things:
- Are you sure, this looks like of_syscon_register() is a static function
- gcc node would be required to add "syscon" compatible
Unless am missing some patches, Am not sure if going via syscon is right
thing here?
Stephen Any comments?
--srini
I think this use case is exactly why that was introduced.
