1 * Calxeda AHCI SATA Controller
3 SATA nodes are defined to describe on-chip Serial ATA controllers.
4 The Calxeda SATA controller mostly conforms to the AHCI interface
5 with some special extensions to add functionality.
6 Each SATA controller should have its own node.
9 - compatible : compatible list, contains "calxeda,hb-ahci"
10 - interrupts : <interrupt mapping for SATA IRQ>
11 - reg : <registers mapping>
14 - dma-coherent : Present if dma operations are coherent
15 - calxeda,port-phys : phandle-combophy and lane assignment, which maps each
16 SATA port to a combophy and a lane within that
18 - calxeda,sgpio-gpio: phandle-gpio bank, bit offset, and default on or off,
19 which indicates that the driver supports SGPIO
20 indicator lights using the indicated GPIOs
21 - calxeda,led-order : a u32 array that map port numbers to offsets within the
23 - calxeda,tx-atten : a u32 array that contains TX attenuation override
24 codes, one per port. The upper 3 bytes are always
26 - calxeda,pre-clocks : a u32 that indicates the number of additional clock
27 cycles to transmit before sending an SGPIO pattern
28 - calxeda,post-clocks: a u32 that indicates the number of additional clock
29 cycles to transmit after sending an SGPIO pattern
