This series:

Add support for Qualcomm's rb8, ride/ride-r3 boards using QCS9075 SoC.

QCS9075 is compatible IoT-industrial grade variant of SA8775p SoC.
Unlike QCS9100, it doesn't have safety monitoring feature of
Safety-Island(SAIL) subsystem, which affects thermal management.

In QCS9100 SoC, the safety subsystem monitors all thermal sensors and
does corrective action for each subsystem based on sensor violation
to comply safety standards. But as QCS9075 is non-safe SoC it requires
conventional thermal mitigation for thermal management.

Difference between Ride & ride-r3 boards is ethernet phy,
ride uses 1G ethernet phy while ride-r3 uses 2.5G ethernet phy.

This series depends on [1] for thermal functionality to work.
