Will that in some way clash with this work if > merged in parallel? Yes I had seen those. I was wondering if I should include them here but opted not too (as it was becoming a massive series). It should be fine to enable RPM later, you just need to be aware that the partition could turn off on a RPM put so you just need to ensure that any register context is saved and restored. By the way, one item I am not certain about is the relationship between the HDMI device and the SOR device. If the HDMI is in the SOR partition it should also have the SOR power-domain populated, but it just uses the SOR, then the SOR driver should handle this.
