1* 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
