* 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; };
