The Calxeda sata_highbank driver has been adding its descriptions to the ahci driver. Separate them properly. This patch only affects documentation and has no functional component.

* 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>;
|
|
};
