John Crispin 3c1f6e358d ipq806x: Add support for IPQ806x chip family
Patches are generated using the "format-patch" command from the
following location:
*https://www.codeaurora.org/cgit/quic/kernel/galak-msm/log/?h=apq_ipq_base
*rev=0771849495b4128cac2faf7d49c85c729fc48b20
Patches numbered 76/77/102/103 have already been integrated in 3.14.12,
so they're not in this list.

All these patches are either integrated are pending integration into
kernel.org, therefore these patches should go away once the kernel
gets upgraded to 3.16.

Support is currently limited to AP148 board but can be extended to other
platforms in the future.

These changes do not cover ethernet connectivity.

+* 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, contains "qcom,msm-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
+
+Example:
+ sata@29000000 {
+ compatible = "qcom,ipq806x-ahci", "qcom,msm-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";
+
+ phys = <&sata_phy>;
+ phy-names = "sata-phy";
+ };
