    ide: (hopefully) fix VDMA for CS5520 · aea5d375
    Bartlomiej Zolnierkiewicz authored
    * Set the correct hwif->dma_base for the second channel in
    * Remove DMA enable code from cs5520_set_pio_mode(), this can
      be handled by the generic ->dma_host_on method now.
    * Add VDMA check to ide_config_drive_speed().
    * drive->using_dma was never enabled since cs5520 host driver's
      ->ide_dma_on method overrided the generic ->ide_dma_on (so
      __ide_dma_on() was never called, drive->using_dma was never set
      and VDMA was never used since it depends on drive->using_dma).
      Fix it by using ->dma_host_on method instead of ->ide_dma_on
      (also add matching ->dma_host_off method).
