i.MX8MP adding HD3SS3220 Type-C cause Wake on LAN failed

AlanWen — Wed, 31 Dec 2025 03:30:00 GMT

I'm working on the 6.12.34 kernel and modifying the kernel device tree imx8mp-evk.dts.

nxp-imx/imx-manifest: i.MX Release Manifest (imx-linux-walnascar)

When added the hd3ss3220 type-c controller in the device tree as follow, WOL failed.

/{ connector { compatible = "usb-c-connector"; label = "USB-C"; data-role = "dual"; status = "disabled"; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; hs_ep: endpoint { remote-endpoint = <&usb3_hs_ep>; }; }; port@1 { reg = <1>; ss_ep: endpoint { remote-endpoint = <&hd3ss3220_in_ep>; }; }; }; }; }; &iomux { pinctrl_hd3ss3220: hd3ss3220grp { fsl,pins = < MX8MP_IOMUXC_ECSPI2_MISO__GPIO5_IO12 0x140 >; }; }; &i2c2 { clock-frequency = <400000>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_i2c2>; status = "okay"; hd3ss3220@67 { compatible = "ti,hd3ss3220"; reg = <0x67>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_hd3ss3220>; interrupt-parent = <&gpio5>; interrupts = <12 IRQ_TYPE_LEVEL_LOW>; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; hd3ss3220_in_ep: endpoint { remote-endpoint = <&ss_ep>; }; }; port@1 { reg = <1>; hd3ss3220_out_ep: endpoint { remote-endpoint = <&usb3_role_switch>; }; }; }; }; }; &usb_dwc3_1 { dr_mode = "otg"; hnp-disable; srp-disable; adp-disable; usb-role-switch; status = "okay"; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; usb3_hs_ep: endpoint { remote-endpoint = <&hs_ep>; }; }; port@1 { reg = <1>; usb3_role_switch: endpoint { remote-endpoint = <&hd3ss3220_out_ep>; }; }; }; };

The WOL function failed after calling the suspend command.

As I checked the wake up is supported

root@imx8mpevk:~# ethtool -s eth0 wol g root@imx8mpevk:~# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Full 100baseT/Full 1000baseT/Full Supported pause frame use: Symmetric Receive-only Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: 10baseT/Full 100baseT/Full 1000baseT/Full Advertised pause frame use: Symmetric Receive-only Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Link partner advertised pause frame use: Symmetric Link partner advertised auto-negotiation: Yes Link partner advertised FEC modes: Not reported Speed: 1000Mb/s Duplex: Full Auto-negotiation: on master-slave cfg: preferred slave master-slave status: slave Port: Twisted Pair PHYAD: 1 Transceiver: external MDI-X: Unknown Supports Wake-on: ug Wake-on: g Current message level: 0x0000003f (63) drv probe link timer ifdown ifup Link detected: yes

But the same setting of the device tree on 6.6.52 kernel (imx-linux-scarthgap) worked well !!

Could anybody help me ?

Hi @AlanWen ,

I checked the HD3SS3220 dts node, the HD3SS3220 driver is using IRQF_TRIGGER_FALLING, can you try to use IRQ_TYPE_EDGE_FALLING in dts? And set MX8MP_IOMUXC_ECSPI2_MISO__GPIO5_IO12 to 0x1c4.

if (client->irq > 0) { ret = devm_request_threaded_irq(&client->dev, client->irq, NULL, hd3ss3220_irq_handler, IRQF_TRIGGER_FALLING | IRQF_ONESHOT, "hd3ss3220", &client->dev);

Best Regards,
Zhiming

There is a syntax error while compiling the linux-imx kernel device tree.

It seem to be no definition of "IRQF_TRIGGER_FALLING", do I need to include a file ?

Hi,

Please try to use IRQ_TYPE_EDGE_FALLING in dts.

Although changing the interrupt signal as "IRQ_TYPE_EDGE_FALLING", the wake-up function still didn't work.

Currently, the wake-up function worked well using the following setup.

/ { connector { compatible = "usb-c-connector"; label = "USB-C"; data-role = "dual"; status = "disabled"; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; hs_ep: endpoint { remote-endpoint = <&usb3_hs_ep>; }; }; port@1 { reg = <1>; ss_ep: endpoint { remote-endpoint = <&hd3ss3220_in_ep>; }; }; }; }; }; &i2c2 { clock-frequency = <400000>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_i2c2>; status = "okay"; hd3ss3220@67 { compatible = "ti,hd3ss3220"; reg = <0x67>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_hd3ss3220>; interrupt-parent = <&gpio5>; interrupts = <12 IRQ_TYPE_LEVEL_LOW>; wakeup-source; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; hd3ss3220_in_ep: endpoint { remote-endpoint = <&ss_ep>; }; }; port@1 { reg = <1>; hd3ss3220_out_ep: endpoint { remote-endpoint = <&usb3_role_switch>; }; }; }; }; }; &iomux { pinctrl_hd3ss3220: hd3ss3220grp { fsl,pins = < MX8MP_IOMUXC_ECSPI2_MISO__GPIO5_IO12 0x140 // USB_SW_INTn (AH20) >; }; }; &usb3_phy1 { fsl,phy-tx-preemp-amp-tune-microamp = <1800>; fsl,phy-tx-vref-tune-percent = <116>; status = "okay"; }; &usb3_1 { status = "okay"; }; &usb_dwc3_1 { dr_mode = "otg"; hnp-disable; srp-disable; adp-disable; usb-role-switch; role-switch-default-mode = "host"; snps,dis-u1-entry-quirk; snps,dis-u2-entry-quirk; status = "okay"; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; usb3_hs_ep: endpoint { remote-endpoint = <&hs_ep>; }; }; port@1 { reg = <1>; usb3_role_switch: endpoint { remote-endpoint = <&hd3ss3220_out_ep>; }; }; }; };

But as you can see, the connector's status is set as "disabled", why ?

When we remove this line, the wake-up function failed.

Hi @AlanWen

In my personal opinion, this issue is likely related to the upgrade of kernel generic components and should not be attributed to i.MX-related drivers. Since I don't have the same hardware platform, I can't pinpoint exactly where the problem lies.

But the wakeup function was worked in 6.6.52 kernel version using the same setup without the connector status line.

As follow:

/ { connector { compatible = "usb-c-connector"; label = "USB-C"; data-role = "dual"; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; hs_ep: endpoint { remote-endpoint = <&usb3_hs_ep>; }; }; port@1 { reg = <1>; ss_ep: endpoint { remote-endpoint = <&hd3ss3220_in_ep>; }; }; }; }; }; &i2c2 { clock-frequency = <400000>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_i2c2>; status = "okay"; hd3ss3220@67 { compatible = "ti,hd3ss3220"; reg = <0x67>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_hd3ss3220>; interrupt-parent = <&gpio5>; interrupts = <12 IRQ_TYPE_LEVEL_LOW>; wakeup-source; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; hd3ss3220_in_ep: endpoint { remote-endpoint = <&ss_ep>; }; }; port@1 { reg = <1>; hd3ss3220_out_ep: endpoint { remote-endpoint = <&usb3_role_switch>; }; }; }; }; }; &iomux { pinctrl_hd3ss3220: hd3ss3220grp { fsl,pins = < MX8MP_IOMUXC_ECSPI2_MISO__GPIO5_IO12 0x140 // USB_SW_INTn (AH20) >; }; }; &usb3_phy1 { fsl,phy-tx-preemp-amp-tune-microamp = <1800>; fsl,phy-tx-vref-tune-percent = <116>; status = "okay"; }; &usb3_1 { status = "okay"; }; &usb_dwc3_1 { dr_mode = "otg"; hnp-disable; srp-disable; adp-disable; usb-role-switch; role-switch-default-mode = "host"; snps,dis-u1-entry-quirk; snps,dis-u2-entry-quirk; status = "okay"; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; usb3_hs_ep: endpoint { remote-endpoint = <&hs_ep>; }; }; port@1 { reg = <1>; usb3_role_switch: endpoint { remote-endpoint = <&hd3ss3220_out_ep>; }; }; }; };
