AM6548: PHY subsystem selection

Tony Tang

Part Number: AM6548

in the on line user guide, there is not description for AM65xx, as there is not any such information in datasheet.

in the menuconfig, different with non AM65xx device, I think the default selection set for AM65xx, but some customer need user guide describe it to pass internal review, so need factory team confirm and update the user guide.

    Keerthy,

    Sorry for not clear.

    #1. In the user guide about PHY subsystem, there is not clear guide for AM65x. 

    #2. In the menuconfig GUI of AM65x SDK,  options of PHY subsystem as below, is the default selections work for AM65x? if yes, please update to user guide.

    Tony,

    For USB 2.0 - CONFIG_OMAP_USB2
    For USB 3.0 - CONFIG_OMAP_USB2 and CONFIG_PHY_AM654_SERDES

    If you have done make linux from the SDK then those options are already taken care of in the tisdk_am65xx-evm_defconfig.

    I have asked for updating documentation for am65xx.

    Best Regards,
    Keerthy
