Subject: [PATCH v5 0/3] mailbox/arm64: qcom: rework compatibles for fallback (continued)

Hi,

Changes since v4
================
v3: https://lore.kernel.org/linux-devicetree/20230322174148.810938-1-krzysztof.kozlowski@linaro.org/
v4: https://lore.kernel.org/linux-devicetree/20230327140752.163009-1-krzysztof.kozlowski@linaro.org/

Important: v3 and v4 are quite different.

v3 did not reach full consensus, so I prepared v4 doing a subset of the
original change. Then DTS pieces from the v3 were applied, without bindings
and driver.  OTOH, bindings and driver were applied from v4.
So we have DTS from v3 and driver+bindings from v4.

This leaves us in inconsistent state and several warnings:
['qcom,msm8976-apcs-kpss-global', 'qcom,msm8994-apcs-kpss-global', 'syscon'] is too long
['qcom,msm8998-apcs-hmss-global', 'qcom,msm8994-apcs-kpss-global'] is too long
['qcom,sm6115-apcs-hmss-global', 'qcom,msm8994-apcs-kpss-global'] is too long
['qcom,sdm660-apcs-hmss-global', 'qcom,msm8994-apcs-kpss-global'] is too long
['qcom,sm6125-apcs-hmss-global', 'qcom,msm8994-apcs-kpss-global'] is too long

Bring back changes from v3, to align bindings and driver with DTS.

Changes since v3
================
1. Narrow the scope of the patches after feedback from Dmitry - only few
   variants are made compatible.

Changes since v2
================
1. Split fixes to separate patchset which is now dependency:
   https://lore.kernel.org/linux-arm-msm/20230322173559.809805-1-krzysztof.kozlowski@linaro.org/T/#t
2. Add Ack
3. No other changes, as discussion with Dmitry did not reach conclusion on incompatibility.

Changes since v1
================
1. Rebase
2. Make msm8994 fallback for several variants, not msm8953, because the latter
   actually might take some clocks.
3. Two new patches for SDX55.
4. Minor corrections in bindings style.
v1: https://lore.kernel.org/all/20230202161856.385825-1-krzysztof.kozlowski@linaro.org/

Best regards,
Krzysztof
