I went and measured the amount of RAM being used by the driver (allocated during boot when the driver is loaded and probed), and it's only 8KB. That's not really much compared to other drivers and subsystems being loaded in the system. Of course RZ/A tries to be RAM sensitive...but 8KB for a clock driver is not my biggest concern. So with that said, I could add in a driver option to not register the reset controller. And, also make a macro so users can specify "36" instead of "306" in the DT. And then, I no longer have to worry about duplicate code (2 drivers do almost the same thing). What do you think? Were you expecting the driver to allocate more than 8K of RAM on boot? Thanks, Chris
