[PATCH v2 0/4] hwspinlock: qcom: Allow dropping the intermediate TCSR mutex syscon

[Bjorn Andersson]

In 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, and in some of these
platforms no other registers in this region is accessed from Linux. Update the
binding and the implementation to allow the TCSR mutex to be represented
without an intermediate syscon node.

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
