Thomas Petazzoni 9a0d5113ac ASoC: kirkwood: enable Kirkwood driver for mvebu platforms
The audio unit found in the Armada 370 SoC is similar to the one used
in the Marvell Kirkwood and Marvell Dove SoCs. Therefore, this commit
allows the Kirkwood audio driver to be built on mvebu platforms, and
adds an additional compatible string to identify the Armada 370
variant of the audio unit.

* mvebu (Kirkwood, Dove, Armada 370) audio controller
Required properties:
- compatible:
"marvell,kirkwood-audio" for Kirkwood platforms
"marvell,dove-audio" for Dove platforms
"marvell,armada370-audio" for Armada 370 platforms
- reg: physical base address of the controller and length of memory mapped
region.
- interrupts:
with "marvell,kirkwood-audio", the audio interrupt
with "marvell,dove-audio", a list of two interrupts, the first for
the data flow, and the second for errors.
- clocks: one or two phandles.
The first one is mandatory and defines the internal clock.
The second one is optional and defines an external clock.
- clock-names: names associated to the clocks:
"internal" for the internal clock
"extclk" for the external clock
Example:
i2s1: audio-controller@b4000 {
compatible = "marvell,dove-audio";
reg = <0xb4000 0x2210>;
interrupts = <21>, <22>;
clocks = <&gate_clk 13>;
clock-names = "internal";
};
