TUSB4020BPHP USB HUB Support

StanleyShen — Fri, 26 Apr 2024 10:04:06 GMT

Hi there

We want to add the TUSB4020BPHP (TI) HUB to S32G2 board,

could you tell me if it is supported by the default driver or if additional driver support is required? If it is an additional driver, can you provide it

Also, for support USB HUB, could you tell us how to modify the dts file

thank you

Hi,

We understand that you are working under Linux, is this correct? If so, which BSP version are you working with?

As for the specific P/N, we understand that there is no list available for specific parts and no information on regards of the P/N is available under the linux source code.

As for general usb-hub support, under "linux/drivers/usb/core" we see that a "hub.c" and "hub.h" files, which seem to be related to this question.

Please, let us know.

Hi Daniel

Thanks for you replay

If so, which BSP version are you working with?

It's BSP35.

Just refer to the 已解决: Porting USB HUB driver - porting TUSB4041 (USB 2.0 HUB) - NXP Community

It seems that the Linux kernel already supports TUSB4041 by default,

but it is uncertain whether TUSB4042 is supported, so I would like to confirm.
Additionally, if a HUB is added to the S32G2 chip, how should it be modified in DTS?

Hi,

Thanks for your feedback.

As seen under the linked community thread, this information should be provided by the vendor itself.

As for modifications, we understand that this should also be provided by the vendor itself.

Please, let us know.
