Subject: [PATCH v2 08/10] ARM: dts: Add devicetree for Nuvoton WPCM450 BMC chip
Date: Tue, 6 Apr 2021 14:09:19 +0200 [thread overview]
Message-ID: <20210406120921.2484986-9-j.neuschaefer@gmx.net> (raw)
In-Reply-To: <20210406120921.2484986-1-j.neuschaefer@gmx.net>
The WPCM450 is an older BMC SoC in the Nuvoton NPCM family, originally
marketed as Winbond WPCM450.
This patch adds a devicetree with basic functionality.
