+* AHCI SATA Controller
+
+SATA nodes are defined to describe on-chip Serial ATA controllers.
+Each SATA controller should have its own node.
+
+It is possible, but not required, to represent each port as a sub-node.
+It allows to enable each port independently when dealing with multiple
+PHYs.
+
+Required properties:
+- compatible        : compatible string, one of:
+  - "allwinner,sun4i-a10-ahci"

+- interrupts        : <interrupt mapping for SATA IRQ>
+- reg               : <registers mapping>
+
+Please note that when using "generic-ahci" you must also specify a SoC specific
+compatible:
+	compatible = "manufacturer,soc-model-ahci", "generic-ahci";
+
+Optional properties:
+- dma-coherent      : Present if dma operations are coherent
+- clocks            : a list of phandle + clock specifier pairs

+- target-supply     : regulator for SATA target power
+- phys              : reference to the SATA PHY node
+- phy-names         : must be "sata-phy"
+- ports-implemented : Mask that indicates which ports that the HBA supports
+		      are available for software to use. Useful if PORTS_IMPL
+		      is not programmed by the BIOS, which is true with
+		      some embedded SOC's.
+
+Required properties when using sub-nodes:
+- #address-cells    : number of cells to encode an address
+- #size-cells       : number of cells representing the size of an address
+
+
+Sub-nodes required properties:
+- reg		    : the port number
+And at least one of the following properties:
+- phys		    : reference to the SATA PHY node
+- target-supply    : regulator for SATA target power
+
+Examples:

+* 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

+
+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.

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

+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.
