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 <quic_schowdhu@quicinc.com> Cc: Bhupesh Sharma <bhupesh.sharma@linaro.org> Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> --- Not tested on hardware. Changes in v2: 1. Disable the EUD node and do not add ports/connector in boards, as discussed with Doug. v1: https://lore.kernel.org/all/CAD=FV=Xt26=rBf99mzkAuwwtb2f-jnKtnHaEhXnthz0a5zke4Q@mail.gmail.com/ --- arch/arm64/boot/dts/qcom/sc7280.dtsi | 21 ++------------------- 1 file changed, 2 insertions(+), 19 deletions(-)
