Subject: [PATCH v7 03/22] dt-bindings: soc: qcom: qcom,saw2: define
 optional regulator node

The SAW2 device can optionally provide a voltage regulator supplying the
CPU core, cluster or L2 cache. Change the boolean 'regulator' property
into a proper regulator description. This breaks schema compatibility
for the sake of properly describing the regulator.
