From 18692b772f3952678c393a41674a308a2158f19d Mon Sep 17 00:00:00 2001 From: max_chen Date: Mon, 2 Jun 2025 10:31:54 +0800 Subject: [PATCH] ARM: dts: sama7d65: Remove the vqmmc-supply property from the sdmmc1 node. On the SAMA7D65 Curiosity development board, the SD CARD (SDMMC1) circuit uses SDMMC1_1V8SEL_PB30 to switch the SD card voltage. If you configure vqmmc-supply = <&vdd_3v3>;, it will force the voltage to stay at 3.3V, preventing high-speed SD cards from operating efficiently. --- arch/arm/boot/dts/microchip/at91-sama7d65_curiosity.dts | 1 - 1 file changed, 1 deletion(-) diff --git a/arch/arm/boot/dts/microchip/at91-sama7d65_curiosity.dts b/arch/arm/boot/dts/microchip/at91-sama7d65_curiosity.dts index 026863e1c5d90..fe5f4d0fe587e 100644 --- a/arch/arm/boot/dts/microchip/at91-sama7d65_curiosity.dts +++ b/arch/arm/boot/dts/microchip/at91-sama7d65_curiosity.dts @@ -632,7 +632,6 @@ &sdmmc1 { bus-width = <4>; vmmc-supply = <&vdd_3v3>; - vqmmc-supply = <&vdd_3v3>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_sdmmc1_default>; status = "okay";
