Dear team,

We are using imx8qm-mek platform running on Android - 9 Auto.

Please let us know if OTG functionalities like HNP and SRP are supported by this BSP release (android_p9.0.0_2.1.1-AUTO-ga)

Please let us know how to validate them.

Hello Amit,

We have not any document to validate this, however there are two USB controllers:

- One is USB2 compatible and the IP comes from ChipIdea (the same USB IP used on mx5/mx6/mx7)

- One is USB3 compatible and the IP comes from Cadence.

The Cadence USB controller is described like this in arch/arm64/boot/dts/freescale/imx8-ss-conn.dtsi:

usbotg3: usb3@5b110000 {
compatible = "Cadence,usb3";

....

The Chipidea USB controller is described like this in arch/arm64/boot/dts/freescale/imx8-ss-conn.dtsi:

usbotg1: usb@5b0d0000 {
compatible = "fsl,imx8qm-usb", "fsl,imx7ulp-usb",
"fsl,imx27-usb";

Regards
