Subject: [PATCH v3 4/4] ASoC: kirkwood: change kirkwood-i2s to
mvebu-pcm-audio and DT doc
As the kirkwood audio system may be used in other Marvell machines
(mvebu), this patch changes the name of the audio driver to
'mvebu-pcm-audio' and also contains the associated DT documentation.
Signed-off-by: Jean-Francois Moine <moinejf@...e.fr>

+* mvebu (Kirkwood, Dove, Armada 370) i2s controller
+
+Required properties:
+
+- compatible: "marvell,mvebu-pcm-audio"
+
+- reg: physical base address of the controller and length of memory mapped
+ region.
+
+- interrupts: list of two irq numbers.
+ The first irq is used for data flow and the second one is used 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@...00 {
+ compatible = "marvell,mvebu-pcm-audio";
+ reg = <0xb4000 0x2210>;
+ interrupts = <21>, <22>;
+ clocks = <&gate_clk 13>;
+ clock-names = "internal";
+};
