Subject: [PATCH 5.10.y-cip 29/29] arm64: dts: renesas: r9a07g044: Create thermal zone to support IPA
Date: Mon,  4 Apr 2022 13:35:53 +0100	[thread overview]
Message-ID: <20220404123553.25851-30-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <20220404123553.25851-1-prabhakar.mahadev-lad.rj@bp.renesas.com>

From: Biju Das <biju.das.jz@bp.renesas.com>

commit 88404c56fde05eb741552a33fdfe6d7d20c1c986 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.
