This patch adds support for the sunxi series of SoC's by allwinner. It
plugs into the ahci-platform framework.
Note: Currently it uses a somewhat hackish approach that probably needs
a lot more work, but does the same as the IMX SoC's.

+Allwinner SUNXI 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 "allwinner,sun4i-a10-ahci"
- compatible: Should contain "allwinner,sun4i-a10-ahci"
+- reg : <registers mapping>
- reg: The offset and length of the MMIO registers.
+- interrupts : <interrupt mapping for AHCI IRQ>
- interrupts: An interrupt-specifier for the ACHI interrupt
+- clocks : clocks for ACHI
+- clock-names : clock names for AHCI
Please _define_ the set of clock-names you expect. This binding is
meaningless without it. If you require clock-names, define the clocks
property in terms of it.
I copied ahci_platform.txt and filled in the missing bits, I will
improve all the above. Appologies!
Thanks,
Mark.
