Subject: [PATCH 0/4] hwspinlock: qcom: Allow dropping the intermediate TCSR mutex syscon

In all modern Qualcomm platforms the mutex region of the TCSR is forked
off into its own block, all with a offset of 0 and stride of 4096.
Update the binding to allow the hardware block to be described directly
on the mmio bus, in addition to allowing the existing syscon based
definition.

Bjorn Andersson (4):
  dt-bindings: hwlock: qcom: Migrate binding to YAML
  dt-bindings: hwlock: qcom: Allow device on mmio bus
  hwspinlock: qcom: Allow mmio usage in addition to syscon
  arm64: dts: qcom: sm8250: Drop tcsr_mutex syscon
