From c2ff5c0282f94c1f1f81007e1fa7378fe95f46d3 Mon Sep 17 00:00:00 2001 From: Biju Das Date: Sun, 1 May 2022 12:29:25 +0100 Subject: [PATCH] arm64: dts: renesas: r9a07g043: 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.
