This series brings DMA support and needs to access the dmamux registers that are in the sysctrl area. I've sent an RTC series which needs to access this area as well, but it is not fully ready yet as it was advised to go for a reset controller in this case. The reset controller would be registered by the clock driver, so yes it would touch the same file. Finally, there is an USB series that is coming soon, I don't know if it will be ready for merge for 5.19, but it needs to access a specific register in this area as well (h2mode). So provided that we are able to contribute this reset driver quickly enough, I would argue that it is safer to merge the clk changes in the clk tree. Thanks, Miquèl
