The efuse at 8000000, unlike the one at 11f10000 and the efuse on all other MediaTek SoCs, does not define any cell, including the socinfo-data ones which the mtk-efuse driver expects to always be present, resulting in the following errors in the log: mtk-socinfo mtk-socinfo.0.auto: error -ENOENT: Failed to get socinfo data mtk-socinfo mtk-socinfo.0.auto: probe with driver mtk-socinfo failed with error -2 The efuse at 8000000 is disabled by default but enabled on mt8183-kukui. Since it is unused, and to prevent the errors from being thrown, disable it on mt8183-kukui. Signed-off-by: Nícolas F. R. A. Prado --- Changes in v3: - Switched to removing the node from MT8183-kukui's DT instead of controlling whether the mtk-socinfo device was registered by mtk-efuse - Link to v2: https://lore.kernel.org/r/20240708-mtk-socinfo-no-data-probe-err-v2-1-7ae252acbcc2@collabora.com Changes in v2: - Added missing include for of.h - Link to v1: https://lore.kernel.org/r/20240708-mtk-socinfo-no-data-probe-err-v1-1-fb2acd3a47bf@collabora.com --- arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi | 4 ---- 1 file changed, 4 deletions(-) --- base-commit: f524a5e4dfb75b277c9a5ad819ca5f035f490f14 change-id: 20240708-mtk-socinfo-no-data-probe-err-d7558343dc82 Best regards, diff --git a/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi b/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi index 6345e969efae..7c8221fe62eb 100644 --- a/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi +++ b/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi @@ -868,10 +868,6 @@ &mfg { domain-supply = <&mt6358_vgpu_reg>; }; -&soc_data { - status = "okay"; -}; - &spi0 { pinctrl-names = "default"; pinctrl-0 = <&spi0_pins>;
