[RFT PATCH 00/12] ARM/hwlock: qcom: switch TCSR mutex to MMIO

[Krzysztof Kozlowski]

Hi,

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

Not tested on hardware. Please kindly provide tests.

[RFT PATCH 01/12] dt-bindings: hwlock: qcom-hwspinlock: add support for MMIO on older SoCs

[Krzysztof Kozlowski]

Older Qualcomm SoCs have TCSR mutex registers with 0x80 stride, instead
of 0x1000.  Add dedicated compatibles for such case.  Unfortunately the
binding started using a generic "qcom,tcsr-mutex" compatible without
specifying the SoC part, thus it looks now quite inconsistent.

If anyone ever says "I want a generic compatible because I am sure all
devices are compatible", that's one more argument they are wrong. :)

[Krzysztof Kozlowski]

The TCSR mutex bindings allow device to be described only with address
space (so it uses MMIO, not syscon regmap).  This seems reasonable as
TCSR mutex is actually a dedicated IO address space and it also fixes DT
schema checks:

  qcom/ipq6018-cp01-c1.dtb: hwlock: 'reg' is a required property

[RFT PATCH 09/12] ARM: dts: qcom: msm8974: split TCSR halt regs out of mutex

[Krzysztof Kozlowski]

The TCSR halt regs are next to TCSR mutex, so before converting the TCSR
mutex into device with address space, we need to split the halt regs to
its own syscon device.  This also describes more accurately the devices
and their IO address space.

[RFT PATCH 10/12] ARM: dts: qcom: msm8974: switch TCSR mutex to MMIO

[Krzysztof Kozlowski]

The TCSR mutex bindings allow device to be described only with address
space (so it uses MMIO, not syscon regmap).  This seems reasonable as
TCSR mutex is actually a dedicated IO address space and it also fixes DT
schema checks:

  qcom-msm8974-sony-xperia-rhine-amami.dtb: tcsr-mutex: 'reg' is a required property
  qcom-msm8974-sony-xperia-rhine-amami.dtb: tcsr-mutex: 'syscon' does not match any of the regexes: 'pinctrl-[0-9]+'
