3 SATA nodes are defined to describe on-chip Serial ATA controllers.
4 Each SATA controller should have its own node.
6 It is possible, but not required, to represent each port as a sub-node.
7 It allows to enable each port independently when dealing with multiple
11 - compatible : compatible string, one of:
12 - "allwinner,sun4i-a10-ahci"
13 - "hisilicon,hisi-ahci"
15 - "marvell,armada-380-ahci"
17 - "snps,exynos5440-ahci"
19 - "fsl,qoriq-ahci" : for qoriq series socs which include ls1021, ls2085, etc.
20 - "fsl,<chip>-ahci" : chip could be ls1021, ls2085 etc.
22 - interrupts : <interrupt mapping for SATA IRQ>
23 - reg : <registers mapping>
25 Please note that when using "generic-ahci" you must also specify a SoC specific
27 compatible = "manufacturer,soc-model-ahci", "generic-ahci";
30 - dma-coherent : Present if dma operations are coherent
31 - clocks : a list of phandle + clock specifier pairs
32 - target-supply : regulator for SATA target power
33 - phys : reference to the SATA PHY node
34 - phy-names : must be "sata-phy"
36 Required properties when using sub-nodes:
37 - #address-cells : number of cells to encode an address
38 - #size-cells : number of cells representing the size of an address
41 Sub-nodes required properties:
42 - reg : the port number
43 And at least one of the following properties:
44 - phys : reference to the SATA PHY node
45 - target-supply : regulator for SATA target power
