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 --- arch/arm64/boot/dts/qcom/sm6115.dtsi | 48 ++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sm6115.dtsi b/arch/arm64/boot/dts/qcom/sm6115.dtsi index f67863561f3f..6865342fc42f 100644 --- a/arch/arm64/boot/dts/qcom/sm6115.dtsi +++ b/arch/arm64/boot/dts/qcom/sm6115.dtsi @@ -180,6 +180,18 @@ core3 { }; }; + eud_typec: connector { + compatible = "usb-c-connector"; + + ports { + port@0 { + con_eud: endpoint { + remote-endpoint = <&eud_con>; + }; + }; + }; + }; + firmware { scm: scm { compatible = "qcom,scm-sm6115", "qcom,scm"; @@ -647,6 +659,35 @@ gcc: clock-controller@1400000 { #power-domain-cells = <1>; }; + eud: eud@1610000 { + compatible = "qcom,sm6115-eud", "qcom,eud"; + reg = <0x0 0x01610000 0x0 0x2000>, + <0x0 0x01612000 0x0 0x1000>, + <0x0 0x003c0000 0x0 0x40000>; + interrupts = ; + qcom,secure-mode-enable; + status = "disabled"; + + ports { + #address-cells = <1>; + #size-cells = <0>; + + port@0 { + reg = <0>; + eud_ep: endpoint { + remote-endpoint = <&usb2_role_switch>; + }; + }; + + port@1 { + reg = <1>; + eud_con: endpoint { + remote-endpoint = <&con_eud>; + }; + }; + }; + }; + usb_hsphy: phy@1613000 { compatible = "qcom,sm6115-qusb2-phy"; reg = <0x0 0x01613000 0x0 0x180>; @@ -1144,6 +1185,13 @@ usb_dwc3: usb@4e00000 { snps,has-lpm-erratum; snps,hird-threshold = /bits/ 8 <0x10>; snps,usb3_lpm_capable; + usb-role-switch; + + port { + usb2_role_switch: endpoint { + remote-endpoint = <&eud_ep>; + }; + }; }; };
