|
+* Qualcomm 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 "qcom,msm-ahci"
|
|
+- interrupts : <interrupt mapping for SATA IRQ>
|
|
+- reg : <registers mapping>
|
|
+- phys : Must contain exactly one entry as specified
|
|
+ in phy-bindings.txt
|
|
+- phy-names : Must be "sata-phy"
|
|
+
|
|
+Required properties for "qcom,ipq806x-ahci" compatible:
|
|
+- clocks : Must contain an entry for each entry in clock-names.
|
|
+- clock-names : Shall be:
|
|
+ "slave_iface" - Fabric port AHB clock for SATA
|
|
+ "iface" - AHB clock
|
|
+ "core" - core clock
|
|
+ "rxoob" - RX out-of-band clock
|
|
+ "pmalive" - Power Module Alive clock
|
|
+
|
|
+Example:
|
|
+ sata@29000000 {
|
|
+ compatible = "qcom,ipq806x-ahci", "qcom,msm-ahci";
|
|
+ reg = <0x29000000 0x180>;
|
|
+
|
|
+ interrupts = <0 209 0x0>;
|
|
+
|
|
+ clocks = <&gcc SFAB_SATA_S_H_CLK>,
|
|
+ <&gcc SATA_H_CLK>,
|
|
+ <&gcc SATA_A_CLK>,
|
|
+ <&gcc SATA_RXOOB_CLK>,
|
|
+ <&gcc SATA_PMALIVE_CLK>;
|
|
+ clock-names = "slave_iface", "iface", "core",
|
|
+ "rxoob", "pmalive";
|
|
+
|
|
+ phys = <&sata_phy>;
|
|
+ phy-names = "sata-phy";
|
|
+ };
