From afa544a2fb6827b5ea8547a69b28115439e14533 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Mon, 16 Jul 2018 16:41:59 +0200 Subject: [PATCH] dt-bindings: ap806: add the thermal node in the syscon file Explain the thermal bindings now that the thermal IP is described being inside of a system controller. Add a reference to the thermal-zone node.
