   12 description: |
   13   This controller is the first Faraday IDE interface block, used in the
   14   StorLink SL3512 and SL3516, later known as the Cortina Systems Gemini
   15   platform. The controller can do PIO modes 0 through 4, Multi-word DMA
   16   (MWDM) modes 0 through 2 and Ultra DMA modes 0 through 6.
   17 
   18   On the Gemini platform, this PATA block is accompanied by a PATA to
   19   SATA bridge in order to support SATA. This is why a phandle to that
   20   controller is compulsory on that platform.
   21 
   22   The timing properties are unique per-SoC, not per-board.
