title: Faraday Technology FTIDE010 PATA controller
maintainers:
- Linus Walleij <linus.walleij@linaro.org>
description: |
This controller is the first Faraday IDE interface block, used in the
StorLink SL3512 and SL3516, later known as the Cortina Systems Gemini
platform. The controller can do PIO modes 0 through 4, Multi-word DMA
(MWDM) modes 0 through 2 and Ultra DMA modes 0 through 6.
On the Gemini platform, this PATA block is accompanied by a PATA to
SATA bridge in order to support SATA. This is why a phandle to that
controller is compulsory on that platform.
The timing properties are unique per-SoC, not per-board.
