* Calxeda AHCI SATA Controller
SATA nodes are defined to describe on-chip Serial ATA controllers.
The Calxeda SATA controller mostly conforms to the AHCI interface
with some special extensions to add functionality.
Each SATA controller should have its own node.
Required properties:
- compatible : compatible list, contains "calxeda,hb-ahci"
- interrupts : <interrupt mapping for SATA IRQ>
- reg : <registers mapping>
Optional properties:
- dma-coherent : Present if dma operations are coherent
- calxeda,port-phys : phandle-combophy and lane assignment, which maps each
SATA port to a combophy and a lane within that
combophy
- calxeda,sgpio-gpio: phandle-gpio bank, bit offset, and default on or off,
which indicates that the driver supports SGPIO
indicator lights using the indicated GPIOs
- calxeda,led-order : a u32 array that map port numbers to offsets within the
SGPIO bitstream.
Example:
sata@ffe08000 {
compatible = "calxeda,hb-ahci";
reg = <0xffe08000 0x1000>;
interrupts = <115>;
dma-coherent;
calxeda,port-phys = <&combophy5 0 &combophy0 0 &combophy0 1
&combophy0 2 &combophy0 3>;
calxeda,sgpio-gpio =<&gpioh 5 1 &gpioh 6 1 &gpioh 7 1>;
calxeda,led-order = <4 0 1 2 3>;
};
