* 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;
};
* 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>;
};
