From 88404c56fde05eb741552a33fdfe6d7d20c1c986 Mon Sep 17 00:00:00 2001 From: Biju Das Date: Wed, 8 Dec 2021 14:27:29 +0000 Subject: [PATCH] arm64: dts: renesas: r9a07g044: Create thermal zone to support IPA Setup a thermal zone driven by SoC temperature sensor. Create passive trip points and bind them to CPUFreq cooling device that supports power extension. Based on the work done by Dien Pham and others for r8a77990 SoC.
