Subject: [PATCH 6/6] arm64: dts: renesas: rzg2l-smarc-som: Add vdd core regulator
Date: Fri, 3 Dec 2021 11:51:54 +0000 [thread overview]
Message-ID: <20211203115154.31864-7-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20211203115154.31864-1-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.
