Subject: [PATCH v3 1/3] arm64: dts: renesas: rzg2ul-smarc-som: Enable serial NOR flash
Date: Fri, 1 Sep 2023 08:59:30 +0100 [thread overview]
Message-ID: <20230901075932.105822-2-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20230901075932.105822-1-biju.das.jz@bp.renesas.com>
Enable Renesas at25ql128a flash connected to QSPI0. Also disable
the node from rzfive-smarc-som as it is untested.
Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>
---
v2->v3:
* Dropped subnodes, as all pins use the same power-source value.
v1->v2:
* Enabled 4-bit tx support
