Subject: [PATCH v2 11/11] ARM: dts: bcm2711: Add vmmc regulator in emmc2
Date:   Fri,  6 Mar 2020 18:44:13 +0100
Message-Id: <20200306174413.20634-12-nsaenzjulienne@suse.de>
In-Reply-To: <20200306174413.20634-1-nsaenzjulienne@suse.de>

Precedence: bulk

The SD card power can be controlled trough a pin routed into the board's
external GPIO expander. Turn that into a regulator and provide it to
emmc2.
