[PATCH 1/5] riscv: dts: spacemit: k3-com260-ifx: Drop wrong SD card vmmc-supply

From: Troy Mitchell

Date: Thu Nov 05 2026 - 03:25:37 EST


The SD card VDD on the K3 CoM260 module comes from a fixed, always-on
3.3 V rail that software cannot control. ALDO4 of the P1 PMIC does not
supply the card, so referencing it as vmmc-supply describes the wrong
power wiring.

Drop the vmmc-supply property. It is optional for a card powered by a
fixed supply, and the SDHCI core then uses the voltages advertised by
the controller.

Fixes: 055044260e7a ("riscv: dts: spacemit: k3: Enable SD card support")
