Merge tag 'hwlock-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux
Pull hwspinlock updates from Bjorn Andersson:
"This introduces a mechanism in the hardware spinlock framework, and
the Qualcomm TCSR mutex driver, for allowing clients to bust locks
held by a remote processor in the event that this enters a faulty
state while holding the shared lock"
* tag 'hwlock-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux:
hwspinlock: qcom: implement bust operation
hwspinlock: Introduce hwspin_lock_bust()
