ASoC: Updates for v4.6 

The main thing in terms of the core this time around has been some
 additional framework work for dynamic topologies (though we *still*
 don't appear to have a stable ABI for the topology code, it's probably
 worth considering if this will ever happen...).  Otherwise the work has
 almost all been in the drivers:
 
  - HDMI support for Sky Lake, along with other fixes and enhancements
    for the Intel drivers.
  - Lots of improvements to the Renesas drivers.
  - Capture support for Qualcomm drivers.
  - Support for TI DaVinci DRA7xxx devices.
  - New machine drivers for Freescale systems with Cirrus CODECs,
    Mediatek systems with RT5650 CODECs.
  - New CPU drivers for Allwinner S/PDIF controllers
  - New CODEC drivers for Maxim MAX9867 and MAX98926 and Realtek RT5514.

---------------------------------------------------
1 BE 'big-endian'
2 LE 'little-endian'
3 Native 'native-endian'
For one device driver, which will run in different scenarios above
on different SoCs using the devicetree, we need one way to simplify
this.
Required properties:
- {big,little}-endian: these are boolean properties, if absent
meaning that the CPU and the Device are in the same endianness mode,
these properties are for register values and all the buffers only.
Optional properties:
- {big,little,native}-endian: these are boolean properties, if absent
then the implementation will choose a default based on the device
being controlled. These properties are for register values and all
the buffers only. Native endian means that the CPU and device have
the same endianness.
Examples:
Scenario 1 : CPU in LE mode & device in LE mode.

Renesas R-Car sound
=============================================
* Modules
=============================================
Renesas R-Car sound is constructed from below modules
(for Gen2 or later)
SCU : Sampling Rate Converter Unit
- SRC : Sampling Rate Converter
- CMD
- CTU : Channel Transfer Unit
- MIX : Mixer
- DVC : Digital Volume and Mute Function
SSIU : Serial Sound Interface Unit
SSI : Serial Sound Interface
See detail of each module's channels, connection, limitation on datasheet
=============================================
* Multi channel
=============================================
Multi channel is supported by Multi-SSI, or TDM-SSI.
Multi-SSI : 6ch case, you can use stereo x 3 SSI
TDM-SSI : 6ch case, you can use TDM
=============================================
* Enable/Disable each modules
=============================================
See datasheet to check SRC/CTU/MIX/DVC connect-limitation.
DT controls enabling/disabling module.
${LINUX}/arch/arm/boot/dts/r8a7790-lager.dts can be good example.
This is example of
Playback: [MEM] -> [SRC2] -> [DVC0] -> [SSIU0/SSI0] -> [codec]
Capture: [MEM] <- [DVC1] <- [SRC3] <- [SSIU1/SSI1] <- [codec]
&rcar_sound {
...
rcar_sound,dai {
dai0 {
playback = <&ssi0 &src2 &dvc0>;
capture = <&ssi1 &src3 &dvc1>;
};
};
};
You can use below.
${LINUX}/arch/arm/boot/dts/r8a7790.dts can be good example.
&src0 &ctu00 &mix0 &dvc0 &ssi0
&src1 &ctu01 &mix1 &dvc1 &ssi1

&src5 &ctu10 &ssi5
&src6 &ctu11 &ssi6
&src7 &ctu12 &ssi7
&src8 &ctu13 &ssi8
&src9 &ssi9
=============================================
* SRC (Sampling Rate Converter)
=============================================
[xx]Hz [yy]Hz
------> [SRC] ------>
SRC can convert [xx]Hz to [yy]Hz. Then, it has below 2 modes
Asynchronous mode: input data / output data are based on different clocks.
you can use this mode on Playback / Capture
Synchronous mode: input data / output data are based on same clocks.
This mode will be used if system doesn't have its input clock,
for example digital TV case.
you can use this mode on Playback
------------------
** Asynchronous mode
------------------
You need to use "renesas,rsrc-card" sound card for it.
example)
sound {
compatible = "renesas,rsrc-card";
...
/*
* SRC Asynchronous mode setting
* Playback:
* All input data will be converted to 48kHz
* Capture:
* Inputed 48kHz data will be converted to
* system specified Hz
*/
convert-rate = <48000>;
...
cpu {
sound-dai = <&rcar_sound>;
};
codec {
...
};
};
------------------
** Synchronous mode
------------------
> amixer set "SRC Out Rate" on
> aplay xxxx.wav
> amixer set "SRC Out Rate" 48000
> amixer set "SRC Out Rate" 44100
=============================================
* CTU (Channel Transfer Unit)
=============================================
[xx]ch [yy]ch
------> [CTU] -------->
CTU can convert [xx]ch to [yy]ch, or exchange outputed channel.
CTU conversion needs matrix settings.
For more detail information, see below

cpu {
sound-dai = <&rcar_sound>;
};
codec {
...
};
};
Ex) Exchange output channel
Input -> Output
1ch -> 0ch
0ch -> 1ch
example of using matrix
output 0ch = (input 0ch x 0) + (input 1ch x 1)
output 1ch = (input 0ch x 1) + (input 1ch x 0)

amixer set "CTU SV1" 4194304,0
example of changing connection
amixer set "CTU Reset" on
amixer set "CTU Pass" 2,1
=============================================
* MIX (Mixer)
=============================================
MIX merges 2 sounds path. You can see 2 sound interface on system,
and these sounds will be merged by MIX.
aplay -D plughw:0,0 xxxx.wav &
aplay -D plughw:0,1 yyyy.wav
You need to use "renesas,rsrc-card" sound card for it.
Ex)

[MEM] -> [SRC2] -> [CTU03] -+
sound {
compatible = "renesas,rsrc-card";

playback = <&src1 &ctu02 &mix0 &dvc0 &ssi0>;
};
dai1 {
playback = <&src2 &ctu03 &mix0 &dvc0 &ssi0>;
};
};
};
=============================================
* DVC (Digital Volume and Mute Function)
=============================================
DVC controls Playback/Capture volume.
Playback Volume
amixer set "DVC Out" 100%
Capture Volume
amixer set "DVC In" 100%
Playback Mute
amixer set "DVC Out Mute" on
Capture Mute
amixer set "DVC In Mute" on
Volume Ramp
amixer set "DVC Out Ramp Up Rate" "0.125 dB/64 steps"
amixer set "DVC Out Ramp Down Rate" "0.125 dB/512 steps"
amixer set "DVC Out Ramp" on
aplay xxx.wav &
amixer set "DVC Out" 80% // Volume Down
amixer set "DVC Out" 100% // Volume Up
=============================================
* SSIU (Serial Sound Interface Unit)
=============================================
There is no DT settings for SSIU, because SSIU will be automatically
selected via SSI.
SSIU can avoid some under/over run error, because it has some buffer.
But you can't use it if SSI was PIO mode.
In DMA mode, you can select not to use SSIU by using "no-busif" on DT.
&ssi0 {
no-busif;
};
=============================================
* SSI (Serial Sound Interface)
=============================================
** PIO mode
You can use PIO mode which is for connection check by using.
Note: The system will drop non-SSI modules in PIO mode
even though if DT is selecting other modules.
&ssi0 {
pio-transfer
};
** DMA mode without SSIU
You can use DMA without SSIU.
Note: under/over run, or noise are likely to occur
&ssi0 {
no-busif;
};
** PIN sharing
Each SSI can share WS pin. It is based on platform.
This is example if SSI1 want to share WS pin with SSI0
&ssi1 {
shared-pin;
};
** Multi-SSI
You can use Multi-SSI.
This is example of SSI0/SSI1/SSI2 (= for 6ch)
&rcar_sound {
...
rcar_sound,dai {
dai0 {
playback = <&ssi0 &ssi1 &ssi2 &src0 &dvc0>;
};
};
};
** TDM-SSI
You can use TDM with SSI.
This is example of TDM 6ch.
Driver can automatically switches TDM <-> stereo mode in this case.
rsnd_tdm: sound {
compatible = "simple-audio-card";
...
simple-audio-card,cpu {
