Subject: [PATCH v9 3/4] arm64: dts: renesas: r9a09g047: Add TSU node
Date: Wed, 17 Sep 2025 19:01:57 +0200	[thread overview]
Message-ID: <20250917170202.197929-4-john.madieu.xa@bp.renesas.com> (raw)
In-Reply-To: <20250917170202.197929-1-john.madieu.xa@bp.renesas.com>

Add TSU node along with thermal zones and keep it enabled in the SoC DTSI.

Signed-off-by: John Madieu <john.madieu.xa@bp.renesas.com>

v1 -> v2: Fix IRQ names
v2 -> v3: remove useless 'renesas,tsu-operating-mode' property'
v3 -> v4: no changes
v5: no changes
v6: no changes
v7: updated both property name and specifier (<phandle offset>) for trim property.
v8: removed #address-cells property
v9: no changes
