Hi All,

I am working on a custom board for IMX8M processor ,and we want to use USB3.0 port as a usb hub. We are planning to use cypress USB3314 as usb hub controller. So I want to have steps to integrate it in device tree. And do I need to add a new device driver for usb 3314 hub as I can't find any driver specific to it.

Hi pratik

usually such guidelines are provided by hub chip vendors, may be useful to look on

CY4613 HX3 Hub Linux Driver | Cypress Developer Community

example of i.MX8M dts file:

linux/arch/arm64/boot/dts/freescale/fsl-imx8mq-evk.dts

fsl-imx8mq-evk.dts\freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel

Best regards
igor
