-* Faraday Technology FTIDE010 PATA controller
-
-This controller is the first Faraday IDE interface block, used in the
-StorLink SL2312 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

-
-The timing properties are unique per-SoC, not per-board.
-
-Required properties:
-- compatible: should be one of
-  "cortina,gemini-pata", "faraday,ftide010"
-  "faraday,ftide010"
-- interrupts: interrupt for the block
-- reg: registers and size for the block
-
-Optional properties:
-- clocks: a SoC clock running the peripheral.
-- clock-names: should be set to "PCLK" for the peripheral clock.
-
-Required properties for "cortina,gemini-pata" compatible:
-- sata: a phande to the Gemini PATA to SATA bridge, see
-  cortina,gemini-sata-bridge.txt for details.
