[alsa-devel] Imx6 i2s master driver without i2c
Hello Alsa dev!
Anyone have an example of an i2s only driver for imx6 solo? I need a driver without i2c....
Hi there, Arnaud had a neat patch here that lets you set up a dummy sound card from the DTS.
http://mailman.alsa-project.org/pipermail/alsa-devel/2015-November/100896.ht...
With that patch, you can set up your DTS to simply start streaming, no codec or anything required, which should work for a codec with no I2C.
Hope that helps, -Caleb

Dear Alsa, Caleb and Arnaud
I need to output an i2s master stream from my IMX6 solo board
my board have this configuration for sound: (it have an sgtl5000 codec not on module, but on dev board)

Hi Nikola, Here is my working setup for a wandboard with no i2c codecs.
https://github.com/ccrome/linux-caleb-dev/blob/v4.5-caleb-wandboard/arch/arm...
You need to be sure to set up the audmux right. I'm not sure with that old kernel if everything with audmux works right or not -- I haven't tested it.
That should get you pretty close to what you need for your board I suspect.
That branch (v4.5-caleb-wandboard) will build and run the SSI3 port on AUD5 port, with the mx6 in master mode. And, with all arnaud's patches (included already in that repo), it will actually be robust.

Hello Caleb thanks for your help
Here's my current dts I want to use ssi1 on port 4 I added #sound-dai-cells = <0>; on ssi1 because simple card complaijning about it (what is that?? I could not find documentation about it)
Now the driver says: asoc-simple-card sound.26: snd-soc-dummy-dai <-> 2028000.ssi mapping ok
and

Hi Nikola, Here is my working setup for a wandboard with no i2c codecs.
https://github.com/ccrome/linux-caleb-dev/blob/v4.5-caleb-wandboard/arch/arm...
You need to be sure to set up the audmux right. I'm not sure with that old kernel if everything with audmux works right or not -- I haven't tested it.
That should get you pretty close to what you need for your board I suspect.
That branch (v4.5-caleb-wandboard) will build and run the SSI3 port on AUD5 port, with the mx6 in master mode. And, with all arnaud's patches (included already in that repo), it will actually be robust.

Hi there, Arnaud had a neat patch here that lets you set up a dummy sound card from the DTS.
http://mailman.alsa-project.org/pipermail/alsa-devel/2015-November/100896.ht...
With that patch, you can set up your DTS to simply start streaming, no codec or anything required, which should work for a codec with no I2C.
Hope that helps, -Caleb

Hi Nicola,
Answers inline. BTW, it's highly preferred on this list that you don't 'top-post', which I had to look up when I was told not to do it :-). Basically, put replies below the stuff they refer to, not above, so somebody coming into the middle of the conversation later can read it in a normal top to bottom order rather than a bottom to top, or worse yet, some combination.

Yeah, I don't really understand how that stuff works. I just have a working setup, so I go with it.

Are you using the new kernel I pointed you to (v4.5) , or still the old 3.14? I don't have my system up right now to check against what mine looks like.
For the most part, people on this list are on the latest kernel, and are not terribly motivated to go back and figure out problems with old kernels.
but if I try to play a file it hangs and nothing escape
How I can debug the various modules? ssi, dma, ???
Well, the way I do it is with lots and lots of printk's, and a really fast automated way to rebuild/copy/reboot the kernel (a custom makefile that does it all for me).
I don't see anything obviously wrong with your DTS, but I'm no expert.
You might want to try with a v4.5 kernel to see if that makes any difference. Sorry I can't be of more help, but kernel hacking is definitely not my main job :-)

I'd put printk's where in the audmux driver where the DT's 'fsl,port-config' is parsed and used, and make sure it's all getting read properly. You need to trace the signal settings from the pin, through the iomux, audmux and finally to the SSI. Something's not right somewhere, but I don't really know.

I think that I need to : init dma to transfer from ssi1 (what file???) init ssi1 with a clock and a mode (i2s master) (i think fsl_ssi or imx-ssi file?? ) init audmux to put ssi1 (port 1) to port 4 (is a clock needed?) (imx-audmux module??) init iomux to put port4 output on output pin (I need to set pin direction also or is automatic???) (only in dts? what function set that?)
and where those init are? and what file/function does the actual memory transfer? and ... last how I can check separately all those things?? I can init ssi for example without audio as a "serial port" and test it??? or I can Init the output port as gpio and set pins to test if its initializated??
How I can read the cpu register back from linux to check that are correctly initializated (for example I can read iomux registers????) The documentation/tutorial on alsa driver are very scarse, and freescale community is not of help
Thanks for your help

In pricipal, but you don't want to mess with the structure that's in place.
How I can read the cpu register back from linux to check that are correctly initializated (for example I can read iomux registers????)
Yes, use printk from fsl_ssi.c For example:
u32 stcr_val; regmap_read(regs, CCSR_SSI_STCR, &stcr_val); printk(KERN_INFO "This is the STCR register: 0x%08x\n", strc_val);
There is also a regmap entry in /sys that has your ssi values there, which can be great for reading all the register values at once. However, these are really only useful when the port is open. Generally, I want to see the values are they are written into the registers so I can see exampley what's going on..

Yeah, it's all a bit complicated, and I don't understand most of it. But, the good news is that you shouldn't really have to deal with much of it. The SSI is already connected to the DMA and the DMA is connected to user space, so that's not something you need to worry about. The things you need to make sure of is that the pins & audmux & SSI are configured properly via the device tree, and you shouldn't really need to do much more than that.
It sounds like you're not getting your TX clock into master mode, right? It should start generating a master clock when you start recording and playing back from your sound card.
For example, looking at the IMX6DQRM.pdf (section 61.8.1.4 among others), you'll want SSI.TXDIR set to 1 (generate bit clock) and TFDIR set to 1 (generated frame sync).
The way these bits are set is a bit round-about. But here goes:
For master mode, (for simple-audio-card anyway), in your DTB you set:
simple-audio-card,frame-master = <&sound2_ssi>; simple-audio-card,bitclock-master = <&sound2_ssi>;
(see here https://github.com/ccrome/linux-caleb-dev/blob/b9bf92b9d9f2121bab38d5e927faa...).
This tells the simple-audio-card driver (here: http://lxr.free-electrons.com/source/sound/soc/generic/simple-card.c#L278) to set the DAI format so that the SSI is master. This will in turn call fsl_set_dai_fmt here: http://lxr.free-electrons.com/source/sound/soc/fsl/fsl_ssi.c#L1044, which should set the TDDIR and TXDIR bits appropriately.
So, I'd put prink's in fsl_ssi_set_dai_fmt and to see what's actually getting set, just to check.
Are you successfully getting it set to master mode?
Are you getting a clock? This is trickier for me since I totally don't understand how the clock tree stuff works. But, if you use SSI3 instead of SSI1, my config should work. Is there any reason you're using the other SSI?
For me, once I got the audmux directions right, the bits started flying out of the port (but only when the alsa device is open).

also you have a typo in your dts I think that the define is
#define AUDMUX_EXT_PORT_NAME port5
not
#define AUDMUX_INT_PORT_NAME port5
and -> correct the other
(i found that imx-audmux support audmux port-config...)

Right, I wish I understood how to do that. I don't. It's got something to do with some function called 'clock' I bet :-) Or maybe 'clk'. Or maybe in the DTS and not a function call...
In my kernel (3.14.28-1.0.0_ga+g91cf351) some of the statement in you dts are not supported in simple driver so I stripped down the imx-si476 driver and use with your dummy codec driver
Yeah, that's the problem with old kernels. I try to just look towards the future :-)
I'm glad things are working, and thanks for posting your working DTS. Having your DTS here may help the next guy with an old kernel.
Cheers -Caleb

Ok I'm almost there
Now I have an audio driver that works in both recording / playing
The only bug that I have is this:
I have this function that set the clock based on the stream properties i tested it with: speaker-test -r 48000
Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 3840 to 17280 Period size range from 1920 to 1920 Using max buffer size 17280
but my function get everytime 44100 no matter what I put in -r parameter as playback frequency!!!!
configuration rate=44100, format=2, channels=2, bclk=2822400 fsl-ssi-dai 202c000.ssi: set tdm slots channels=2 fsl-ssi-dai 202c000.ssi: set ssi bclk NAME=202c000.ssi
what I'm missing??
and the function
snd_soc_dai_set_pll(cpu_dai, 0, 0, 24000000, itel_audio_fmts[i].sysclk);
is correct??? I need to set pll4 frequency based on rate

Caleb thanks for your help!!!! the documentation is really orrible!!!!
but now I'm getting something out of TXD!!!!
Wooo!
only no clock and very fast (I think that I need to configure the oscillator/pll and iomux???)
Right, I wish I understood how to do that. I don't. It's got something to do with some function called 'clock' I bet :-) Or maybe 'clk'. Or maybe in the DTS and not a function call...
In my kernel (3.14.28-1.0.0_ga+g91cf351) some of the statement in you dts are not supported in simple driver so I stripped down the imx-si476 driver and use with your dummy codec driver
Yeah, that's the problem with old kernels. I try to just look towards the future :-)
I'm glad things are working, and thanks for posting your working DTS. Having your DTS here may help the next guy with an old kernel.
Cheers -Caleb

Ok I'm almost there
Now I have an audio driver that works in both recording / playing
The only bug that I have is this:
I have this function that set the clock based on the stream properties i tested it with: speaker-test -r 48000
Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 3840 to 17280 Period size range from 1920 to 1920 Using max buffer size 17280
but my function get everytime 44100 no matter what I put in -r parameter as playback frequency!!!!
configuration rate=44100, format=2, channels=2, bclk=2822400 fsl-ssi-dai 202c000.ssi: set tdm slots channels=2 fsl-ssi-dai 202c000.ssi: set ssi bclk NAME=202c000.ssi
what I'm missing??
and the function
snd_soc_dai_set_pll(cpu_dai, 0, 0, 24000000, itel_audio_fmts[i].sysclk);
is correct??? I need to set pll4 frequency based on rate
I'm not terribly sure how this stuff is supposed to work, but it looks like the clock frequency should be set in
fsl_ssi_set_bclk (http://lxr.free-electrons.com/source/sound/soc/fsl/fsl_ssi.c#L650)
It looks like the it can (depending on settings) call clk_set_rate. I really should read the docs on the clock system. It's all a mystery to me. But, I suspect that'll eventually call a FSL specific clock setter, which should automatically get to the clocks you need and set the values you need. I think there's a big table that describes how all the clocks are interrelated.
I'm sure somebody else knows how this works :-)
Let me know what you discover.

Caleb thanks for your help!!!! the documentation is really orrible!!!!
but now I'm getting something out of TXD!!!!
Wooo!
only no clock and very fast (I think that I need to configure the oscillator/pll and iomux???)
Right, I wish I understood how to do that. I don't. It's got something to do with some function called 'clock' I bet :-) Or maybe 'clk'. Or maybe in the DTS and not a function call...
In my kernel (3.14.28-1.0.0_ga+g91cf351) some of the statement in you dts are not supported in simple driver so I stripped down the imx-si476 driver and use with your dummy codec driver
Yeah, that's the problem with old kernels. I try to just look towards the future :-)
I'm glad things are working, and thanks for posting your working DTS. Having your DTS here may help the next guy with an old kernel.
Cheers -Caleb
