The register handling is fine. But how do we deal with resource handling?
e.g. the block that has the deep-core registers might need to be clocked or

Yeah I saw this in the code there.
In this case it seems syscon-type regmap access can be used to
read/write the registers, so maybe the pin controller also need to
get a handle on some clock etc?
Uhh, let's not go there.. The resource availability needs to be
handled transparently in regmap code and the reg provider hardware
module driver using runtime PM.
OK we can surely discuss this with broonie, it makes sense to
have regmap be able to do its deed transparently.
Yes I think so too. Sounds like we need callbacks for the runtime PM
checks to the "register provider" driver. Hwo knows, maybe those
features are there already :)
Hi Tony,
Any conclusion on using regmap for omap control module non-mux registers ?
Thanks and Regards,
