Subject: [PATCH] ARM: dts: imx6q-h100: use usdhc2 VSELECT
Date: Fri, 15 Dec 2017 10:26:24 +0100 [thread overview]
Message-ID: <20171215092624.12806-1-m.tretter@pengutronix.de> (raw)
The uSDHC controller directly provides a VSELECT signal that can be
muxed to the external voltage select. Mux the VSELECT directly to avoid
using a GPIO.
