-* Cortina Systems Gemini SATA Bridge
-
-The Gemini SATA bridge in a SoC-internal PATA to SATA bridge that
-takes two Faraday Technology FTIDE010 PATA controllers and bridges
-them in different configurations to two SATA ports.
-
-Required properties:
-- compatible: should be
-  "cortina,gemini-sata-bridge"
-- reg: registers and size for the block
-- resets: phandles to the reset lines for both SATA bridges
-- reset-names: must be "sata0", "sata1"
-- clocks: phandles to the compulsory peripheral clocks
-- clock-names: must be "SATA0_PCLK", "SATA1_PCLK"
-- syscon: a phandle to the global Gemini system controller
-- cortina,gemini-ata-muxmode: tell the desired multiplexing mode for
-  the ATA controller and SATA bridges. Values 0..3:
-  Mode 0: ata0 master <-> sata0
-          ata1 master <-> sata1
-          ata0 slave interface brought out on IDE pads
-  Mode 1: ata0 master <-> sata0
-          ata1 master <-> sata1
-          ata1 slave interface brought out on IDE pads
-  Mode 2: ata1 master <-> sata1
-          ata1 slave  <-> sata0
-          ata0 master and slave interfaces brought out
-               on IDE pads
-  Mode 3: ata0 master <-> sata0
-          ata0 slave  <-> sata1
-          ata1 master and slave interfaces brought out
-               on IDE pads
-
-Optional boolean properties:
-- cortina,gemini-enable-ide-pins: enables the PATA to IDE connection.
-  The muxmode setting decides whether ATA0 or ATA1 is brought out,
-  and whether master, slave or both interfaces get brought out.
-- cortina,gemini-enable-sata-bridge: enables the PATA to SATA bridge
-  inside the Gemnini SoC. The Muxmode decides what PATA blocks will
-  be muxed out and how.
-
-Example:
-
-sata: sata@46000000 {
-	compatible = "cortina,gemini-sata-bridge";
-	reg = <0x46000000 0x100>;
-	resets = <&rcon 26>, <&rcon 27>;
-	reset-names = "sata0", "sata1";
-	clocks = <&gcc GEMINI_CLK_GATE_SATA0>,
-		 <&gcc GEMINI_CLK_GATE_SATA1>;
-	clock-names = "SATA0_PCLK", "SATA1_PCLK";
-	syscon = <&syscon>;
-	cortina,gemini-ata-muxmode = <3>;
-	cortina,gemini-enable-ide-pins;
-	cortina,gemini-enable-sata-bridge;
-};
