Merge tag 'hwlock-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull hwspinlock updates from Bjorn Andersson:
 "This removes the need for representing the Qualcomm SFPB mutex using
  an intermediate syscon node and it clean up the pm_runtime_get_sync()
  usage in the OMAP hwspinlock driver"

* tag 'hwlock-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux:
  hwspinlock: qcom: Add support for mmio usage to sfpb-mutex
  hwspinlock: using pm_runtime_resume_and_get instead of pm_runtime_get_sync
