12description: |
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.
