[PATCH v2 2/4] arm64: dts: imx8mp-kontron: Drop vmmc-supply to fix SD card on SMARC eval carrier

From: Frieder Schrempf <hidden>
Date: 2026-02-20 10:36:53
Also in: imx, linux-devicetree, lkml
Subsystem: arm/freescale imx / mxc arm architecture, the rest · Maintainers: Frank Li, Sascha Hauer, Linus Torvalds

From: Frieder Schrempf <redacted>

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")
