Subject: [PATCH v2 2/4] arm64: dts: imx8mp-kontron: Drop vmmc-supply to fix SD card on SMARC eval carrier
Date: Fri, 20 Feb 2026 11:36:17 +0100	[thread overview]
Message-ID: <20260220103636.9697-3-frieder@fris.de> (raw)
In-Reply-To: <20260220103636.9697-1-frieder@fris.de>

From: Frieder Schrempf <frieder.schrempf@kontron.de>

The SMARC evaluation carrier provides an SD card power switch that
complies with the OSM standard definition. The OSM base devicetree
already describes this correctly.

Stop overriding the vmmc-supply in the board devicetree and rely on
the definition from the OSM base DTS instead to fix the power supply
configuration for the SD card.

Fixes: 6fe1ced5ccab7 ("arm64: dts: Add support for Kontron i.MX8MP SMARC module and eval carrier")
