    Subject[PATCH 3/5] viafb: select HW scaling on VX900 for IGA2
    Date
    VX900 can do hardware scaling for both IGAs in contrast to previous
    hardware which could do it only for IGA2. This patch ensures that
    we set the parameter for IGA2 and not for IGA1. This fixes hardware
    scaling on VX900 until we have the infrastructure to support it for
    both IGAs.
