Subject: [PATCH 2/4] arm64: dts: imx8mp-kontron: Fix SD card supply on SMARC eval carrier
Date: Wed, 18 Feb 2026 14:25:06 +0100	[thread overview]
Message-ID: <20260218132519.74570-3-frieder@fris.de> (raw)
In-Reply-To: <20260218132519.74570-1-frieder@fris.de>

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

The SMARC eval carrier has a power switch for the SD card compliant
to the OSM standard definition. To use this as already specified in
the OSM base devicetree, stop overriding it in the board tree.

This fixes the power-supply for the SC card.

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