HD3SS3220: Linux drivers for HD3SS3220

Arun kumar

Part Number: HD3SS3220

Hi Team,

I am planning to use HD3SS3220IRNHT on Jetson AGX Xavier platform with kernel-4.9. I need both Host and Device mode functionality.

Can you please provide me the Linux kernel drivers(for kernel-4.9) and device tree entries to bring up HD3SS3220IRNHT

Thanks,

Arun

Use of I2C is optional but strongly encouraged and provides additional control of the HD3SS3220. But the device does not require a driver, you only have to attend its interrupts and check the status of the port via the GPIOs or I2C registers.

Thanks for reply.

without device driver how the Host/Device switching will happen?

Please refer to section 7.3.3 of the HD3SS3220 datasheet. The HD3SS3220 will be configured in DRP (dual role port) mode and will automatically switch between the host/device mode base on the CC1/CC2 voltage condition.

Thanks
