|
|
|
|
|
|
|
|
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"
|

|
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.
