This is a bit more complicated then it should be as we can get a regulator from a device node only when a device is attached to it, so this series starts by moving the power domains into a device. Overall this series makes the clock handling nicer because we no longer have to use of_clk_get(), but can use a plain devm_clk_bulk_get_all() to retrieve the domain clocks. All this is needed for the RK3568-EVB board where the power domain of the GPU is supplied by an external regulator.
