From 4bc9f44d581be66718cf7cf6e649fb92b3c2e6c6 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Tue, 19 May 2026 06:12:37 +0200 Subject: [PATCH] riscv: dts: spacemit: enable eMMC on Milk-V Jupiter The Milk-V Jupiter board has a connector for an eMMC module. Add an entry for it in the device tree and alias it mmc0. Mark the device as non-removable as eMMC modules have no CD pin and are not supposed to be inserted or removed while the system is running. On systems without an eMMC module installed, the kernel emits the following informational message during boot: mmc0: SDHCI controller on d4281000.mmc [d4281000.mmc] using ADMA mmc0: Failed to initialize a non-removable card Signed-off-by: Aurelien Jarno Reviewed-by: Yixun Lan Link: https://patch.msgid.link/20260519041458.3287843-4-aurelien@aurel32.net Signed-off-by: Yixun Lan --- arch/riscv/boot/dts/spacemit/k1-milkv-jupiter.dts | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/arch/riscv/boot/dts/spacemit/k1-milkv-jupiter.dts b/arch/riscv/boot/dts/spacemit/k1-milkv-jupiter.dts index fbba33992347..1a833e716cb6 100644 --- a/arch/riscv/boot/dts/spacemit/k1-milkv-jupiter.dts +++ b/arch/riscv/boot/dts/spacemit/k1-milkv-jupiter.dts @@ -16,6 +16,7 @@ ethernet1 = ð1; i2c2 = &i2c2; i2c8 = &i2c8; + mmc0 = &emmc; serial0 = &uart0; }; @@ -105,6 +106,16 @@ status = "okay"; }; +&emmc { + bus-width = <8>; + mmc-hs400-1_8v; + mmc-hs400-enhanced-strobe; + non-removable; + no-sd; + no-sdio; + status = "okay"; +}; + ð0 { phy-handle = <&rgmii0>; phy-mode = "rgmii-id";
