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.
