[PATCH 00/15] arm: dts: Fix OPP and cooling device properties

[Viresh Kumar]

This fixes missing OPP and cooling device properties for CPUs for the
ARM 32 bit platforms. This is build tested by the zero day testing
infrastructure as well.

Individual maintainers can pick the patches to their SoC trees or I will
ask ARM SoC maintainers to pick them up later.

[PATCH 08/15] arm: dts: dra74x: Add missing cooling device properties for CPUs

[Viresh Kumar]

The cooling device properties, like "#cooling-cells" and
"dynamic-power-coefficient", should either be present for all the CPUs
of a cluster or none. If these are present only for a subset of CPUs of
a cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.

Add such missing properties.

Fix other missing properties (clocks, supply, clock latency) as well to
make it all work.

Applying this one into omap-for-v4.19/dt thanks.
