Subject: [PATCH v2 3/3] arm64: dts: renesas: rzg2l-smarc-som: Add vdd core regulator
Date: Mon, 6 Dec 2021 15:00:25 +0000 [thread overview]
Message-ID: <20211206150025.15703-4-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20211206150025.15703-1-biju.das.jz@bp.renesas.com>
Add vdd core regulator (1.1 V).
This patch add regulator support for gpu.
On the H/W manual nothing mentioned about gpu
regulator. So using vdd core regulator for gpu.
