There was a small mistake when first introducing this controller driver: the power-domain property was missing in the device tree because there was only one controller supported at this time (UART) and this is a Synopsis IP which did not support power domains. The idea is to always use these power domains when available, so let's add it to the bindings, the DT and use it from the driver through the runtimpe PM API instead of doing raw clk API calls. Changes in v4: * Use pm_runtime_resume_and_get() instead of pm_runtime_get_sync(). Changes in v3: * Moved the pm_runtime calls earlier in the probe to avoid possible register accesses while the clocks have not yet been enabled. Changes in v2: * Dropped the DT patch merged by Geert. * Used devm_pm_runtime_enable() instead of pm_runtime_enable() and dropped the pm_runtime_disable() calls. * Used pm_runtime_resume_and_get() instead of pm_runtime_get_sync(). * Collected the tags on the bindings.
