From 55196e9dbe34e44162f00c83231199f37d3238dc Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sun, 20 Aug 2023 09:56:26 +0200 Subject: [PATCH] arm64: dts: qcom: sc7280: drop incorrect EUD port on SoC side [ Upstream commit 39c8af78cbefb8c71a5ad1fa088e761ef418f0a0 ] Qualcomm Embedded USB Debugger (EUD) second port should point to Type-C USB connector. Such connector was defined directly in root node of sc7280.dtsi which is clearly wrong. SC7280 is a chip, so physically it does not have USB Type-C port. The connector is usually accessible through some USB switch or controller. Doug Anderson said that he wasn't ever able to use EUD on Herobrine boards, probably because of invalid or missing DTS description - DTS is saying EUD is on usb_2 node, which is connected to a USB Hub, not to the Type-C port. Correct the EUD/USB connector topology by removing the top-level fake USB connector and EUD port pointing to it, and disabling the incomplete EUD device node. This fixes also dtbs_check warnings: sc7280-herobrine-crd.dtb: connector: ports:port@0: 'reg' is a required property Link: https://lore.kernel.org/all/CAD=FV=Xt26=rBf99mzkAuwwtb2f-jnKtnHaEhXnthz0a5zke4Q@mail.gmail.com/ Fixes: 9ee402ccfeb1 ("arm64: dts: qcom: sc7280: Fix EUD dt node syntax") Cc: Souradeep Chowdhury Cc: Bhupesh Sharma Signed-off-by: Krzysztof Kozlowski Reviewed-by: Douglas Anderson Link: https://lore.kernel.org/r/20230820075626.22600-1-krzysztof.kozlowski@linaro.org Signed-off-by: Bjorn Andersson Signed-off-by: Sasha Levin --- arch/arm64/boot/dts/qcom/sc7280.dtsi | 21 ++------------------- 1 file changed, 2 insertions(+), 19 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/sc7280.dtsi b/arch/arm64/boot/dts/qcom/sc7280.dtsi index 20231d80c504..91bb58c6b1a6 100644 --- a/arch/arm64/boot/dts/qcom/sc7280.dtsi +++ b/arch/arm64/boot/dts/qcom/sc7280.dtsi @@ -649,18 +649,6 @@ }; }; - eud_typec: connector { - compatible = "usb-c-connector"; - - ports { - port@0 { - con_eud: endpoint { - remote-endpoint = <&eud_con>; - }; - }; - }; - }; - memory@80000000 { device_type = "memory"; /* We expect the bootloader to fill in the size */ @@ -3625,6 +3613,8 @@ <0 0x88e2000 0 0x1000>; interrupts-extended = <&pdc 11 IRQ_TYPE_LEVEL_HIGH>; + status = "disabled"; + ports { #address-cells = <1>; #size-cells = <0>; @@ -3635,13 +3625,6 @@ remote-endpoint = <&usb2_role_switch>; }; }; - - port@1 { - reg = <1>; - eud_con: endpoint { - remote-endpoint = <&con_eud>; - }; - }; }; }; -- 2.34.1
