Add device tree binding for Qualcomm AHCI SATA controller and specifically
the sata controller on the IPQ806x family of SoCs.
We can utilize the "generic-ahci" platform driver with the addition of the
sata phy to enable SATA support on Qualcomm SoCs with AHCI controllers.
Signed-off-by: Kumar Gala <galak@codeaurora.org>
---
v5:
* Moved to using "generic-ahci" binding support and assigned-clocks
so we can use upstream generic ahci support w/o a special driver.
Updated binding spec to reflect that.
v4:
* Added simple PM ops implementation
* Added setting of pmalive clk
v3:
* Added comment about suspend/resume not supported
* Fixup ahci_platform_init_host for upstream change to interface
* cleanup error handling of rxoob clk, moved to devm_clk_get/put
v2:
* Fixed MODULE_LICENSE to be GPL v2

+* 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:

+- 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

+ 100Mhz (100000000) for SATA_RXOOB_CLK
