Subject: [PATCH v3 00/15] ARM/hwlock: qcom: switch TCSR mutex to MMIO

Hi,

Switch older Qualcomm SoCs to use MMIO-based method instead of syscon.

Not tested on hardware. Please kindly provide tests.

Changes since v2
================
1. Rebase on current MFD changes.
2. Add Rb tag.
3. Split MFD patch to separate patchset:
https://lore.kernel.org/linux-devicetree/20220909091056.128949-1-krzysztof.kozlowski@linaro.org/T/#u

Changes since v1
================
1. Use existing qcom,tcsr-msm8974 compatible.
2. Fix few other TCSR syscon compatibles (new patches: ipq6018, msm8953,
   qcs404, msm8996).
3. New patch: dt-bindings: mfd: qcom,tcsr: drop simple-mfd from IPQ6018
4. New patch: dt-bindings: mfd: qcom,tcsr: add QCS404

Dependencies
============
1. DT bindings and driver patches can go via hwlock. DTS via Bjorn/Qualcomm.

2. The last five DTS commits (ARM and arm64) named "switch TCSR mutex to MMIO"
   depend on driver support. The changes are not bisectable, just like
   previously such changes were not bisectable:
   https://lore.kernel.org/all/20200622075956.171058-5-bjorn.andersson@linaro.org/
   Therefore these changes could wait for next release.

Best regards,
Krzysztof
