- * 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>;
- };
