Subject: [PATCH 2/3] arm64: dts: renesas: r9a09g011: Add watchdog node
Date: Thu, 3 Nov 2022 22:39:55 +0000 [thread overview]
Message-ID: <20221103223956.50575-3-fabrizio.castro.jz@renesas.com> (raw)
In-Reply-To: <20221103223956.50575-1-fabrizio.castro.jz@renesas.com>
The r9a09g011 (a.k.a. RZ/V2M) comes with two watchdog IPs,
but Linux is only allowed one.
Add a node for the watchdog allowed to Linux to the SoC
specific dtsi.
