Subject: [Patch v4 6/7] dt-bindings: soc: qcom: Extend RPMh power controller binding to describe thermal warming device
Date: Wed, 20 Nov 2019 07:56:32 -0500
Message-ID: <1574254593-16078-7-git-send-email-thara.gopinath@linaro.org> (raw)
In-Reply-To: <1574254593-16078-1-git-send-email-thara.gopinath@linaro.org>

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 <thara.gopinath@linaro.org>

v3->v4:
	- 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.
