These patches are written from scratch, though. There are two parts: part 1: Elaine's series used to contain patches for the VO1GRF handling, but they were dropped at some point because of the CLK_NR_CLKS feedback from the DT maintainers. I added some code, that should hopefully fix everyones concerns by figuring out the right number at runtime. I also moved the correct handling of pclk_vo0grf/pclk_vo1grf before proper handling of GATE_LINK clocks, so that it can be merged ASAP. These patches are needed for HDMI RX/TX support on RK3588. part 2: For proper GATE_LINK support I tried implementing the suggestion from Stephen Boyd to use clk PM operations by creating MFD dynamically. This required some restructuring, since CLK_OF_DECLARE() is called before devices are available. All of this can be found in the last patch of this series.
