Regarding USB hub driver and UART controller driver availability on pro5 kernel

Other Parts Discussed in Thread: TL16C2752

Hi,

 

  We are making custom board, in that we are interfacing ISP1520 USB hub controller chip with dm6446.

   I searched in both pro-4 and pro5 kernel, I dint found any hub controller driver, Do we need to have specific driver controller chip or is it universal?

   For UART port expansion we are using TL16C2752 external UART controller, even I dint found any driver for this.

    Please let me know do we already have driver for the above chips or do we need to write driver for this.  If available please provide us the drivers.

Thanks and Regards

    For the Hub chip you would not need seperate driver it should work by default.

    For the uart bridge chip it should work with the serial class driver that is part of the kernel.  If not refer to the data sheet to identify the need for a seperate driver.

    Thanks swamy for your quick replay.

    Regarding UART controller we are using EMIF interface from dm6446 to the controller, datasheet does not tell anything about the driver requirement.

    Is there any UART contrller driver availble for any part number, so that I can use it as refernce??

    Regards
