* Broadcom SATA3 AHCI Controller
|
|
|
|
SATA nodes are defined to describe on-chip Serial ATA controllers.
|
|
Each SATA controller should have its own node.
|
|
|
|
Required properties:
|
|
- compatible : should be one or more of
|
|
"brcm,bcm7216-ahci"
|
|
"brcm,bcm7425-ahci"
|
|
"brcm,bcm7445-ahci"
|
|
"brcm,bcm-nsp-ahci"
|
|
"brcm,sata3-ahci"
|
|
"brcm,bcm63138-ahci"
|
|
- reg : register mappings for AHCI and SATA_TOP_CTRL
|
|
- reg-names : "ahci" and "top-ctrl"
|
|
- interrupts : interrupt mapping for SATA IRQ
|
|
|
|
Optional properties:
|
|
|
|
- reset: for "brcm,bcm7216-ahci" must be a valid reset phandle
|
|
pointing to the RESCAL reset controller provider node.
|
|
- reset-names: for "brcm,bcm7216-ahci", must be "rescal".
|

Example:
|
|
|
|
sata@f045a000 {
|
|
compatible = "brcm,bcm7445-ahci", "brcm,sata3-ahci";
|
|
reg = <0xf045a000 0xa9c>, <0xf0458040 0x24>;
|
|
reg-names = "ahci", "top-ctrl";
|
|
interrupts = <0 30 0>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|

|
sata0: sata-port@0 {
|
|
reg = <0>;
|
|
phys = <&sata_phy 0>;

};

|
|
sata1: sata-port@1 {
