These patches temporarily introduce a IMR-LX4 driver that uses Runtime PM to control clocks and power when performing a basic reset of the device.
The user should check console printouts and verify that register settings are changed after the reset has been performed during probe().
Not intended for upstream merge. Successfully tested on H3 ES2 ULCB.
Created as an example of how to test power domains for a certain device. I hope to use this approach to test IPMMU power domain support in the future.
