| 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. |
