Merge tag 'pmdomain-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/linux-pm

Pull pmdomain updates from Ulf Hansson:
 "Core:
   - Log a message when unused PM domains gets disabled
   - Scale down parent/child performance states in the reverse order

  Providers:
   - qcom: rpmpd: Add power domains support for MSM8974, MSM8974PRO,
     PMA8084 and PM8841
   - renesas: rcar-gen4-sysc: Reduce atomic delays
   - renesas: rcar-sysc: Adjust the waiting time to cover the worst case
   - renesas: r8a779h0-sysc: Add support for the r8a779h0 PM domains
   - imx: imx8mp-blk-ctrl: Add the fdcc clock to the hdmimix domains
   - imx: imx8mp-blk-ctrl: Error out if domains are missing in DT

  Improve support for multiple PM domains:
   - Add two helper functions to attach/detach multiple PM domains
   - Convert a couple of drivers to use the new helper functions"
