Subject[Patch v4 6/7] dt-bindings: soc: qcom: Extend RPMh power controller binding to describe thermal warming device
RPMh power controller hosts mx domain that can be used as thermal warming
device. Add #cooling-cells property to the power domain provider node to
indicate this.

Signed-off-by: Thara Gopinath <>
- Removed subnode to indicate that mx power domain is a warming
device. Instead #cooling-cells is used as a power domain
provider property to indicate if the provider hosts a power
domain that can be used as a warming device.
