* 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
|
||
|
|
|
||
|
|

|
||
|
|
