* 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
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.

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.

Example:

ata@63000000 {
	compatible = "cortina,gemini-pata", "faraday,ftide010";
	reg = <0x63000000 0x100>;
	interrupts = <4 IRQ_TYPE_EDGE_RISING>;
	clocks = <&gcc GEMINI_CLK_GATE_IDE>;
	clock-names = "PCLK";
	sata = <&sata>;
};
