Subject: [PATCH 1/3] dt-bindings: power: renesas,rzg2l-sysc: Add DT binding documentation for SYSC controller
Date: Fri, 4 Jun 2021 19:09:31 +0100 [thread overview]
Message-ID: <20210604180933.16754-2-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <20210604180933.16754-1-prabhakar.mahadev-lad.rj@bp.renesas.com>
Add DT binding documentation for SYSC controller found on
RZ/G2{L,LC,UL} SoC's.
SYSC block contains the LSI_DEVID register which is used to retrieve
SoC product information.
