Add the Embedded USB Debugger(EUD) device tree node for SM6115 / SM4250 SoC. The node contains EUD base register region, EUD mode manager register region and TCSR Base register region along with the interrupt entry. Also add the typec connector node for EUD which is attached to EUD node via port. EUD is also attached to DWC3 node via port. To enable the role switch, we need to set dr_mode = "otg" property for 'usb_dwc3' sub-node in the board dts file. Also the EUD device can be enabled on a board once linux is boot'ed by setting: $ echo 1 > /sys/bus/platform/drivers/qcom_eud/../enable Signed-off-by: Bhupesh Sharma <bhupesh.sharma@linaro.org> --- arch/arm64/boot/dts/qcom/sm6115.dtsi | 51 ++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+)
