2023-02-14dt-bindings: cpufreq: qcom-cpufreq-nvmem: make cpr bindings optionalChristian Marangi
The qcom-cpufreq-nvmem driver supports 2 kind of devices: - pre-cpr that doesn't have power-domains and base everything on nvmem cells and multiple named microvolt bindings. Doesn't need required-opp binding in the opp nodes as they are only used for genpd based devices. - cpr-based that require power-domain in the cpu nodes and use various source to decide the correct voltage and freq Require required-opp binding since they need to be linked to the related opp-level. When the schema was introduced, it was wrongly set to always require these binding but this is not the case for pre-cpr devices. Make the power-domain and the required-opp optional and set them required only for qcs404 based devices.

2022-07-20dt-bindings: arm: qcom: add missing QCS404 board compatiblesKrzysztof Kozlowski
Document board compatibles already present in Linux kernel. In itself this resulted in a dt_binding_check in qcom-cpufrq-nvmem.yaml, which was reported by Rob, solved in below change by Krzysztof and acked by Viresh. The fix is squashed into this to avoid bisect problems.

2022-05-12dt-bindings: cpufreq: mediatek: Add MediaTek CCI propertyRex-BC Chen
MediaTek Cache Coherent Interconnect (CCI) uses software devfreq module for scaling clock frequency and adjust voltage. The phandle could be linked between CPU and MediaTek CCI for some MediaTek SoCs, like MT8183 and MT8186. The reason we need the link status between cpufreq and MediaTek cci is cpufreq and mediatek cci could share the same regulator in some MediaTek SoCs. Therefore, to prevent the issue of high frequency and low voltage, we need to use this to make sure mediatek cci is ready.

Now that we have yaml bindings for the thermal subsystem, get rid of the old bindings (thermal.txt). Replace all references to thermal.txt in the Documentation with a link to the appropriate YAML bindings using the following search and replace pattern: - If the reference is specific to the thermal-sensor-cells property, replace with a pointer to thermal-sensor.yaml - If the reference is to the cooling-cells property, replace with a pointer to thermal-cooling-devices.yaml - If the reference is generic thermal bindings, replace with a reference to thermal*.yaml.

In preparation for using the multi_regulator capability of this driver for handling the ABB LDO for OPP1G of the omap36xx we have to take care that the (legacy) vdd-supply name is cpu0-supply = <&vcc>; To do this we add another field to the SoC description table which optionally can specify a list of regulator names. For omap36xx we define "cpu0-supply" and "vbb-supply". The default remains "vdd-supply" and "vbb-supply". Signed-off-by: H.
