Changes since v3: ---------------- - v3 can be viewed here: https://www.spinics.net/lists/linux-arm-msm/msg137025.html - Addressed Konrad's review comments regarding mainly the driver code. Also fixed the .dtsi as per his comments. - Also collected his R-B for [PATCH 1/5]. Changes since v2: ---------------- - v2 can be viewed here: https://www.spinics.net/lists/linux-arm-msm/msg137025.html - Addressed Bjorn and Krzysztof's comments. - Added [PATCH 1/5] which fixes the 'qcom_eud' sysfs path. - Added [PATCH 5/5] to enable EUD for Qualcomm QRB4210-RB2 boards. Changes since v1: ---------------- - v1 can be viewed here: https://lore.kernel.org/linux-arm-msm/20221231130743.3285664-1-bhupesh.sharma@linaro.org - Added Krzysztof in Cc list. - Fixed the following issue reported by kernel test bot: >> ERROR: modpost: "qcom_scm_io_writel" [drivers/usb/misc/qcom_eud.ko] undefined! This series adds the dt-binding and driver support for SM6115 / SM4250 EUD (Embedded USB Debugger) block available on Qualcomm SoCs. It also enables the same for QRB4210-RB2 boards by default (the user still needs to enable the same via sysfs). The EUD is a mini-USB hub implemented on chip to support the USB-based debug and trace capabilities. EUD driver listens to events like USB attach or detach and then informs the USB about these events via ROLE-SWITCH.
