Subject: [PATCH 5.10.y-cip 21/25] arm64: dts: renesas: r9a07g043: Create thermal zone to support IPA
Date: Fri,  2 Sep 2022 10:44:23 +0100	[thread overview]
Message-ID: <20220902094427.116227-22-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20220902094427.116227-1-biju.das.jz@bp.renesas.com>

commit c2ff5c0282f94c1f1f81007e1fa7378fe95f46d3 upstream.

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 <dien.pham.ry@renesas.com>
and others for r8a77990 SoC.
