From fd96a316d2647c7566a41987c8ba32c7d55cfdf1 Mon Sep 17 00:00:00 2001 From: Yuantian Tang Date: Mon, 9 Mar 2020 12:54:11 +0800 Subject: [PATCH] dt-bindings: thermal: make cooling-maps property optional Cooling-maps doesn't have to be a required property because there may be no cooling device on system, or there are no enough cooling devices for each thermal zone in multiple thermal zone cases since cooling devices can't be shared. So make this property optional to remove such limitations. For thermal zones with no cooling-maps, there could be critic trips that can trigger CPU reset or shutdown. So they still can take actions.
