Tom Rini53633a82024-02-29 12:33:36 -05001* Qualcomm AHCI SATA Controller
2
3SATA nodes are defined to describe on-chip Serial ATA controllers.
4Each SATA controller should have its own node.
5
6Required properties:
7- compatible : compatible list, must contain "generic-ahci"
8- interrupts : <interrupt mapping for SATA IRQ>
9- reg : <registers mapping>
10- phys : Must contain exactly one entry as specified
11 in phy-bindings.txt
12- phy-names : Must be "sata-phy"
13
14Required properties for "qcom,ipq806x-ahci" compatible:
15- clocks : Must contain an entry for each entry in clock-names.
16- clock-names : Shall be:
17 "slave_iface" - Fabric port AHB clock for SATA
18 "iface" - AHB clock
19 "core" - core clock
20 "rxoob" - RX out-of-band clock
21 "pmalive" - Power Module Alive clock
22- assigned-clocks : Shall be:
23 SATA_RXOOB_CLK
24 SATA_PMALIVE_CLK
25- assigned-clock-rates : Shall be:
26 100Mhz (100000000) for SATA_RXOOB_CLK
27 100Mhz (100000000) for SATA_PMALIVE_CLK
28
29Example:
30 sata@29000000 {
31 compatible = "qcom,ipq806x-ahci", "generic-ahci";
32 reg = <0x29000000 0x180>;
33
34 interrupts = <0 209 0x0>;
35
36 clocks = <&gcc SFAB_SATA_S_H_CLK>,
37 <&gcc SATA_H_CLK>,
38 <&gcc SATA_A_CLK>,
39 <&gcc SATA_RXOOB_CLK>,
40 <&gcc SATA_PMALIVE_CLK>;
41 clock-names = "slave_iface", "iface", "core",
42 "rxoob", "pmalive";
43 assigned-clocks = <&gcc SATA_RXOOB_CLK>, <&gcc SATA_PMALIVE_CLK>;
44 assigned-clock-rates = <100000000>, <100000000>;

46 phys = <&sata_phy>;
