Merge tag 'pmdomain-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/linux-pm

Pull pmdomain updates from Ulf Hansson:
 "pmdomain core:
   - Allow power-off for out-of-band wakeup-capable devices
   - Drop the redundant call to dev_pm_domain_detach() for the amba bus
   - Extend the genpd governor for CPUs to account for IPIs

  pmdomain providers:
   - bcm: Add support for BCM2712
   - mediatek: Add support for MFlexGraphics power domains
   - mediatek: Add support for MT8196 power domains
   - qcom: Add RPMh power domain support for Kaanapali
   - rockchip: Add support for RV1126B

  pmdomain consumers:
   - usb: dwc3: Enable out of band wakeup for i.MX95
   - usb: chipidea: Enable out of band wakeup for i.MX95"
