* AHCI SATA Controller
SATA nodes are defined to describe on-chip Serial ATA controllers.
Each SATA controller should have its own node.
Required properties:
- compatible : compatible list, contains "calxeda,hb-ahci" or "snps,spear-ahci"
- interrupts : <interrupt mapping for SATA IRQ>
- reg : <registers mapping>
Optional properties:
- 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.
- dma-coherent : Present if dma operations are coherent
Example:
sata@ffe08000 {
compatible = "calxeda,hb-ahci";
reg = <0xffe08000 0x1000>;
interrupts = <115>;
calxeda,port-phys = <&combophy5 0 &combophy0 0 &combophy0 1
&combophy0 2 &combophy0 3>;
};
