Subject: [PATCH v2 3/3] ARM: dts: stm32mp157a-dk1: overwrite regulator for sdmmc node
Date: Tue, 15 Oct 2019 11:33:47 +0200 [thread overview]
Message-ID: <20191015093347.5032-3-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20191015093347.5032-1-o.rempel@pengutronix.de>
There is currently no driver for the STPMIC1, which supplies the 3v3
rail into the SDMMC2. The regulator is on on boot though, so lets
replace it with a fixed regulator till we have a regulator driver for
the STPMIC1.

[afa: replaced /delete-node/ with fixed-regulator]
