-* Samsung I2S controller
-
-Required SoC Specific Properties:
-
-- compatible : should be one of the following.
- - samsung,s3c6410-i2s: for 8/16/24bit stereo I2S.
- - samsung,s5pv210-i2s: for 8/16/24bit multichannel(5.1) I2S with
- secondary fifo, s/w reset control and internal mux for root clk src.
- - samsung,exynos5420-i2s: for 8/16/24bit multichannel(5.1) I2S for
- playback, stereo channel capture, secondary fifo using internal
- or external dma, s/w reset control, internal mux for root clk src
- and 7.1 channel TDM support for playback. TDM (Time division multiplexing)
- is to allow transfer of multiple channel audio data on single data line.
- - samsung,exynos7-i2s: with all the available features of exynos5 i2s,
- exynos7 I2S has 7.1 channel TDM support for capture, secondary fifo
- with only external dma and more no.of root clk sampling frequencies.
- - samsung,exynos7-i2s1: I2S1 on previous samsung platforms supports
- stereo channels. exynos7 i2s1 upgraded to 5.1 multichannel with
- slightly modified bit offsets.
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-- dmas: list of DMA controller phandle and DMA request line ordered pairs.
-- dma-names: identifier string for each DMA request line in the dmas property.
- These strings correspond 1:1 with the ordered pairs in dmas.
-- clocks: Handle to iis clock and RCLK source clk.
-- clock-names:
- i2s0 uses some base clocks from CMU and some are from audio subsystem internal
- clock controller. The clock names for i2s0 should be "iis", "i2s_opclk0" and
- "i2s_opclk1" as shown in the example below.
- i2s1 and i2s2 uses clocks from CMU. The clock names for i2s1 and i2s2 should
- be "iis" and "i2s_opclk0".
- "iis" is the i2s bus clock and i2s_opclk0, i2s_opclk1 are sources of the root
- clk. i2s0 has internal mux to select the source of root clk and i2s1 and i2s2
- doesn't have any such mux.
-- #clock-cells: should be 1, this property must be present if the I2S device
- is a clock provider in terms of the common clock bindings, described in
- ../clock/clock-bindings.txt.
-- clock-output-names (deprecated): from the common clock bindings, names of
- the CDCLK I2S output clocks, suggested values are "i2s_cdclk0", "i2s_cdclk1",
- "i2s_cdclk3" for the I2S0, I2S1, I2S2 devices respectively.
-
-There are following clocks available at the I2S device nodes:
- CLK_I2S_CDCLK - the CDCLK (CODECLKO) gate clock,
- CLK_I2S_RCLK_PSR - the RCLK prescaler divider clock (corresponding to the
- IISPSR register),
- CLK_I2S_RCLK_SRC - the RCLKSRC mux clock (corresponding to RCLKSRC bit in
- IISMOD register).
-
-Refer to the SoC datasheet for availability of the above clocks.
-The CLK_I2S_RCLK_PSR and CLK_I2S_RCLK_SRC clocks are usually only available
-in the IIS Multi Audio Interface.
-
-Note: Old DTs may not have the #clock-cells property and then not use the I2S
-node as a clock supplier.
-
-Optional SoC Specific Properties:
-
-- samsung,idma-addr: Internal DMA register base address of the audio
- sub system(used in secondary sound source).
-- pinctrl-0: Should specify pin control groups used for this controller.
-- pinctrl-names: Should contain only one value - "default".
-- #sound-dai-cells: should be 1.

+Texas Instruments TAS2562 Smart PA
+
+The TAS2562 is a mono, digital input Class-D audio amplifier optimized for
+efficiently driving high peak power into small loudspeakers.
+Integrated speaker voltage and current sense provides for
+real time monitoring of loudspeaker behavior.
+
+Required properties:
+ - #address-cells - Should be <1>.
+ - #size-cells - Should be <0>.
+ - compatible: - Should contain "ti,tas2562".
+ - reg: - The i2c address. Should be 0x4c, 0x4d, 0x4e or 0x4f.
+ - ti,imon-slot-no:- TDM TX current sense time slot.
+
+Optional properties:
+- interrupt-parent: phandle to the interrupt controller which provides
+ the interrupt.
+- interrupts: (GPIO) interrupt to which the chip is connected.
+- shut-down: GPIO used to control the state of the device.
+
+Examples:
+tas2562@4c {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "ti,tas2562";
+ reg = <0x4c>;
