From 33bc5e10165d5239e469bcfa6efee0f13c0f7a36 Mon Sep 17 00:00:00 2001 From: Jerome Brunet Date: Wed, 14 Jan 2026 18:08:53 +0100 Subject: [PATCH] arm64: dts: amlogic: g12: assign the MMC A signal clock [ Upstream commit 3c941feaa363f1573a501452391ddf513394c84b ] The amlogic MMC driver operate with the assumption that MMC clock is configured to provide 24MHz. It uses this path for low rates such as 400kHz. Assign the clock to make sure it is properly configured Fixes: 8a6b3ca2d361 ("arm64: dts: meson: g12a: add SDIO controller") Signed-off-by: Jerome Brunet Reviewed-by: Neil Armstrong Link: https://patch.msgid.link/20260114-amlogic-mmc-clocks-followup-v1-6-a999fafbe0aa@baylibre.com Signed-off-by: Neil Armstrong Signed-off-by: Sasha Levin --- arch/arm64/boot/dts/amlogic/meson-g12-common.dtsi | 3 +++ 1 file changed, 3 insertions(+) diff --git a/arch/arm64/boot/dts/amlogic/meson-g12-common.dtsi b/arch/arm64/boot/dts/amlogic/meson-g12-common.dtsi index 6724405eaa6f..8d8ab775404d 100644 --- a/arch/arm64/boot/dts/amlogic/meson-g12-common.dtsi +++ b/arch/arm64/boot/dts/amlogic/meson-g12-common.dtsi @@ -2431,6 +2431,9 @@ <&clkc CLKID_FCLK_DIV2>; clock-names = "core", "clkin0", "clkin1"; resets = <&reset RESET_SD_EMMC_A>; + + assigned-clocks = <&clkc CLKID_SD_EMMC_A_CLK0>; + assigned-clock-rates = <24000000>; }; sd_emmc_b: mmc@ffe05000 {
