It contains a couple of things, most notably the RPM master stats, detailing per-master (read: per-subsystem) sleep/wake statistics and an interrupt controller that's crucial to achieving full SoC clock and/or power collapse states (the MPM). This series tries to prepare the MSG RAM node to be a host for such devices. Depends on https://lore.kernel.org/linux-arm-msm/20230308011705.291337-1-konrad.dybcio@linaro.org/ to solve a warning in the example. The DTS commits don't add -cells or -ranges, as without children they're not of very much use. They'll be introduced along with subnodes.
