[PATCH 0/4] Add I2S/ADV7511 audio support for ARC AXS10x boards.
ARC AXS10x platforms consist of a mainboard with several peripherals. One of those peripherals is an HDMI output port controlled by ADV7511 transmitter. This patch set adds audio for the ADV7511 transmitter and I2S audio for the AXS10x platform.

[PATCH 3/4] ASoC: dwc: Add I2S HDMI audio support using custom platform driver
From: Jose Abreu
HDMI audio support was added to the AXS board using an
I2S cpu driver and a custom platform driver.
The platform driver supports two channels @ 16 bits with
rates 32k, 44.1k and 48k. ALSA Simple audio card is used to
glue the cpu, platform and codec driver (adv7511).

+ARC PGU
+
+This is a display controller found on several development boards produced
+by Synopsys. The ARC PGU is an RGB streamer that reads the data from a
+framebuffer and sends it to a single digital encoder (usually HDMI).
+
+Required properties:
+ - compatible: "snps,arcpgu"
+ - reg: Physical base address and length of the controller's registers.
+ - clocks: A list of phandle + clock-specifier pairs, one for each
+entry in 'clock-names'.
+ - clock-names: A list of clock names. For ARC PGU it should contain:
+ - "pxlclk" for the clock feeding the output PLL of the controller.
+ - encoder-slave: Phandle of encoder chip.
+
+Required sub-nodes:
+ - port: The PGU connection to an encoder chip. The connection is modelled
+using the OF graph bindings specified in
+Documentation/devicetree/bindings/graph.txt.
+
+Example:
+
+/ {
+ ...
+
+ pgu@0x {
+ compatible = "snps,arcpgu";
+ reg = <0x 0x400>;
+ clocks = <&clock_node>;

+ encoder-slave = <&encoder_node>;
+
+ port {
+ pgu_output: endpoint {
