Subject: [PATCH 0/9] Platform support for thermal management on Junoe

Hi,

The series adds support for thermal management on ARM Juno development
platform. As part of this development, common infrastructure is added
to support registering cpu cooling devices that work with the power
allocator thermal governor.

Patch 1 extends the CPU nodes binding to provide an optional dynamic
power coefficient which can be used to create a dynamic power model
for the CPUs. This model is used to constrain device power consumption
(using power_allocator governor) when the system is thermally
constrained.

Patches 2-3 extends the cpufreq-dt and arm_big_little driver to
register cpu cooling devices with the dynamic coefficient when
provided.

Patches 4-7 create a hwmon sensor driver for sensors provided by SCPI
firmware. Patch 7 adds support for the temperature sensors to register
with the thermal framework. This allows setting up platform thermals
using OF thermal bindings.

The last two patches add support for the sensors and the thermal zones
in the Juno device tree.

The Juno specific patches depend on SCPI and cpufreq patches[0] from Sudeep.

Thanks,
Punit
