* 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, must contain "generic-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
- assigned-clocks : Shall be:
SATA_RXOOB_CLK
SATA_PMALIVE_CLK
- assigned-clock-rates : Shall be:
100Mhz (100000000) for SATA_RXOOB_CLK
100Mhz (100000000) for SATA_PMALIVE_CLK
Example:
sata@29000000 {
compatible = "qcom,ipq806x-ahci", "generic-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";
assigned-clocks = <&gcc SATA_RXOOB_CLK>, <&gcc SATA_PMALIVE_CLK>;
assigned-clock-rates = <100000000>, <100000000>;
phys = <&sata_phy>;
phy-names = "sata-phy";
};
