DM8148, hdvpss: VPDMA HAL initialization

Hello TI' teams.

Please let me know - what number of VPDMA version must be initialized with DM8148 silicon revision 3.
I saw into "vps_init_ti814x.c" in function "vpsiHalInit" next code fragment:

     .....
    /* Call VPDMA init function */
    cpuVer = Vps_platformTI814xGetCpuRev();
    if (cpuVer == VPS_PLATFORM_CPU_REV_2_1)
    {
        vpdmaVer = VPSHAL_VPDMA_VER_1AD;
    }
    else
    {
        vpdmaVer = VPSHAL_VPDMA_VER_286;
    }

    retVal = VpsHal_vpdmaInit(&vpdmaInstParams, vpdmaVer, NULL);
    .....

Is this code will be correct work for PG3.0 and future silicon revisions?
What is differences in functionaltiy between "1AD" and "286" versions of VPSHAL_VPDMA?
I'm working with MCFW.

ThanX alot.
