"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: 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 recpectively.
+
+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 (I2S0).
+Note: Old DTs may not have the #clock-cells, clock-output-names properties
+and then not use the I2S node as a clock supplier.
Optional SoC Specific Properties:
- pinctrl-0: Should specify pin control groups used for this controller.
- pinctrl-names: Should contain only one value - "default".
+
Example:
i2s0: i2s@03830000 {

<&clock_audss EXYNOS_SCLK_I2S>;
clock-names = "iis", "i2s_opclk0", "i2s_opclk1";

+ clock-output-names = "i2s_cdclk0";
samsung,idma-addr = <0x03000000>;
pinctrl-names = "default";
pinctrl-0 = <&i2s0_bus>;
it can be specified via "clocks" if system has
clock node (= common clock), or "system-clock-frequency"
(if system doens't support common clock)
+ If a clock is specified, it is
+ enabled with clk_prepare_enable()
+ in dai startup() and disabled with
+ clk_disable_unprepare() in dai
+ shutdown().

- following features:
- * Reading/writing individual parameters
- * Reading/writing complete channel, effects setup, and amp
- setup data
- * Channel switching
- * Virtual MIDI interface
- * Tuner access
- * Playback/capture/mixer device for any ALSA-compatible PCM
- audio application
- * Signal routing (record clean/processed guitar signal,

- Preliminary support for the Variax Workbench and TonePort

- Say Y here to add code to measure the impulse response of a Line6
- device. This is more accurate than user-space methods since it
- bypasses any PCM data buffering (e.g., by ALSA or jack). This is

-
- There are several features of the Line6 USB driver which require PCM
- data to be exchanged with the device:
- *) PCM playback and capture via ALSA
- *) software monitoring (for devices without hardware monitoring)
- *) optional impulse response measurement
- However, from the device's point of view, there is just a single
- capture and playback stream, which must be shared between these
- subsystems. It is therefore necessary to maintain the state of the
- subsystems with respect to PCM usage. We define several constants of
- the form LINE6_BIT_PCM_<subsystem>_<direction>_<resource> with the
- following meanings:
- *) <subsystem> is one of
- -) ALSA: PCM playback and capture via ALSA
- -) MONITOR: software monitoring
- -) IMPULSE: optional impulse response measurement
- *) <direction> is one of
- -) PLAYBACK: audio output (from host to device)
- -) CAPTURE: audio input (from device to host)
- *) <resource> is one of
- -) BUFFER: buffer required by PCM data stream
- -) STREAM: actual PCM data stream
-
- The subsystems call line6_pcm_acquire() to acquire the (shared)
- resources needed for a particular operation (e.g., allocate the buffer
- for ALSA playback or start the capture stream for software monitoring).
- When a resource is no longer needed, it is released by calling
- line6_pcm_release(). Buffer allocation and stream startup are handled
- separately to allow the ALSA kernel driver to perform them at
- appropriate places (since the callback which starts a PCM stream is not
- allowed to sleep).

+ There are several features of the Line 6 USB driver which require PCM
+ data to be exchanged with the device:
+ *) PCM playback and capture via ALSA
+ *) software monitoring (for devices without hardware monitoring)
+ *) optional impulse response measurement
+ However, from the device's point of view, there is just a single
+ capture and playback stream, which must be shared between these
+ subsystems. It is therefore necessary to maintain the state of the
+ subsystems with respect to PCM usage.
+
+ We define two bit flags, "opened" and "running", for each playback
+ or capture stream. Both can contain the bit flag corresponding to
+ LINE6_STREAM_* type,
+ LINE6_STREAM_PCM = ALSA PCM playback or capture
+ LINE6_STREAM_MONITOR = software monitoring
+ IMPULSE = optional impulse response measurement
+ The opened flag indicates whether the buffer is allocated while
+ the running flag indicates whether the stream is running.
+
+ For monitor or impulse operations, the driver needs to call
+ line6_pcm_acquire() or line6_pcm_release() with the appropriate
+ LINE6_STREAM_* flag.
