Subject: [PATCH 2/2] arm64: dts: renesas: rzg2lc-smarc: Enable microSD on SMARC platform
Date: Mon, 17 Jan 2022 07:51:30 +0000 [thread overview]
Message-ID: <20220117075130.6198-2-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20220117075130.6198-1-biju.das.jz@bp.renesas.com>
This patch enables microSD card slot connected to SDHI1 on RZ/G2LC SMARC
platform by removing the sdhi1 overlay which disabled it and adding the
necessary pinmux required for SDHI1.
