Subject: [PATCH 4/9] ARM: dts: TQma53: ESDHC2: use correct IO lines power supply
Date: Thu,  7 Sep 2017 11:05:25 +0200	[thread overview]
Message-ID: <20170907090530.1241-5-jbe@pengutronix.de> (raw)
In-Reply-To: <20170907090530.1241-1-jbe@pengutronix.de>

According to the devicetree bindings the 'vmmc' power supply is the SD
card's power supply and 'vqmmc' is the IO line's power supply.

The i.MX53's ESDHC2 unit on the 'TQma53' CPU card is dedicated to be used
with an externally connected SD card. The on-board power supply is connected
to the SDHC2 IO lines only. The SD card socket is not part of the CPU card,
so the 'vmmc' info must be part of the baseboard devicetree.
