[PATCH V2 0/2] Sound support for Exynos4412 Odroid X2, U3 board

[PATCH V2 0/2] Sound support for Exynos4412 Odroid X2, U3 board

[Sylwester Nawrocki]

This series adds basic sound support for the Odroid X2/U3 boards.
It relies on specific Exynos Audio Subsystem clock parent and
frequencies being pre-configured.

My full testing git branch has been pushed to:
git://linuxtv.org/snawrocki/samsung.git v3.16-rc1-odroid-sound-clk

It can be browsed at:
http://git.linuxtv.org/cgit.cgi/snawrocki/samsung.git/log/?h=v3.16-rc1-odroid-sound-clk

I didn't use the simple-card since there is going to be added
one more CPU interface using the secondary I2S and IDMA.

[PATCH V2 1/2] ASoC: samsung: Add machine driver for Odroid X2/U3

[Sylwester Nawrocki]

This patch adds the sound subsystem driver for Odroid-X2 and
Odroid-U3 boards. The codec works in I2S master mode; there are
2 separate audio routing paths defined as there are differences
in the signal routing between the X2 and U3 boards, i.e. U3 uses
single jack for headphones and microphone.

[alsa-devel] [PATCH V2 1/2] ASoC: samsung: Add machine driver for Odroid X2/U3

[Sylwester Nawrocki]

This patch adds the sound subsystem driver for Odroid-X2 and
Odroid-U3 boards. The codec works in I2S master mode; there are
2 separate audio routing paths defined as there are differences
in the signal routing between the X2 and U3 boards, i.e. U3 uses
single jack for headphones and microphone.

While upstreaming sound-card driver for Snow board, I had a comment from
Mark to move this to probe, if possible. That way, the clock operations
would be done only once and this function and odroidx2_ops can be
removed altogether.

Thanks for the suggestion, I'll change it for the next iteration.

Could be, although snd_soc_unregister_card() wouldn't release references
to the OF nodes, i.e. there would be no related of_node_put() calls.
And for correctness, the of_node_put() calls should be made _after_
a snd_soc_unregister_card() call, and I can't see how it could be possible
if I left only of_node_put() calls in the odroidx2_audio_remove() callback.

Thanks for the suggestion, I'll change it for the next iteration.

Could be, although snd_soc_unregister_card() wouldn't release references
to the OF nodes, i.e. there would be no related of_node_put() calls.
And for correctness, the of_node_put() calls should be made _after_
a snd_soc_unregister_card() call, and I can't see how it could be possible
if I left only of_node_put() calls in the odroidx2_audio_remove() callback.

Given that the widgets don't have any actions defined and the routing is
all done by DT it might be easier and more flexible to just define all
the widgets all the time and let them hang there if they're not in use,
that way you don't need multiple compatible strings.  If you do that
you're then very close to being able to use simple-card...

Too bad, I noticed this comment only just now.  I'll consider this and
will try again and see how simple-card could be used.  There is also the
samsung-i2s-sec secondary 'overlay' CPU DAI that would need to be handled,
and we have it now internally specified in the machine driver through
cpu_dai_name, rather than cpu_of_node.
There might be some more work in the driver needed to support the
secondary I2S interface generically with DT.

You should be converting the device to DPCM for both that and the
compressed audio path.

[PATCH V2 1/2] ASoC: samsung: Add machine driver for Odroid X2/U3

[Sylwester Nawrocki]

This patch adds the sound subsystem driver for Odroid-X2 and
Odroid-U3 boards. The codec works in I2S master mode; there are
2 separate audio routing paths defined as there are differences
in the signal routing between the X2 and U3 boards, i.e. U3 uses
single jack for headphones and microphone.

Thanks for this! I tested these patches plus the ones in your branch
to integrate with the ODROID.
I tested ODROID-U2's 3.5mm analog headphone jack output with:

# speaker-test -c 2 -t wav -l 2

On my x86 laptop this command takes ~6 seconds and produces audible output:
"Front left, front right, front left, front right"

When those words are reproduced over the speakers, there is a
corresponding message printed to stdout which synchronizes nicely.

On ODROID-U2 the same command doesn't work quite right - execution
takes only 3.5 seconds and the audible output is truncated:
"Front left, front right, front"
and the stdout messages do not really coincide with the audio being
reproduced at that time.

No pulseaudio or anything like that.

Can you reproduce this?

Thanks
Daniel

I could reproduce such behaviour on the U3 board, but only with u-boot
which sets the MPLL clock frequency (fout_mpll) to 880 MHz, rather
than 800 MHz, which was the case in my original environment.
All fout_mpll child clocks have then different frequency values
in both cases.
It's a bit strange though, because frequencies of all the audio
subsystem clocks seem to be same anyway:

# cat /sys/kernel/debug/clk/clk_summary
    ...
    fout_epll                   0           0            192000000
       mout_audss               0           0            192000000
          dout_rp               0           0            19200000
             dout_aud_bus       0           0            19200000
          mout_i2s0             0           0            192000000
             dout_i2s0          0           0            192000000
       sclk_epll                0           0            192000000
          audss                 0           0            192000000

So there might be some other difference I'm overlooking.
Will let you know as soon I find out anything else.

Sylwester

I could reproduce such behaviour on the U3 board, but only with u-boot
which sets the MPLL clock frequency (fout_mpll) to 880 MHz, rather
than 800 MHz, which was the case in my original environment.
All fout_mpll child clocks have then different frequency values
in both cases.
It's a bit strange though, because frequencies of all the audio
subsystem clocks seem to be same anyway:

# cat /sys/kernel/debug/clk/clk_summary
    ...
    fout_epll                   0           0            192000000
       mout_audss               0           0            192000000
          dout_rp               0           0            19200000
             dout_aud_bus       0           0            19200000

             dout_i2s0          0           0            192000000
       sclk_epll                0           0            192000000
          audss                 0           0            192000000

So there might be some other difference I'm overlooking.

Is it still wrong when you set the period manually to 1024, i.e.

# speaker-test -c 2 -t wav -l 2 -p 1024

This command makes the kernel totally hang, weird.

# speaker-test -c 2 -t wav -l 2 -p 1024

This plays back fine.

Could it be a problem with the samsung-i2s driver, not correctly
flushing at the right times?
Or do you think the problem is more likely to be clock-related?

This is known issue with clocks vs. ISP power domain. We should really 
fix this in exynos4 clock driver.

Hard to say right now, but at least we need to test a bit more our 
solutions with different initial clocks configuration.

I could reproduce such behaviour on the U3 board, but only with u-boot
which sets the MPLL clock frequency (fout_mpll) to 880 MHz, rather
than 800 MHz, which was the case in my original environment.
All fout_mpll child clocks have then different frequency values
in both cases.
It's a bit strange though, because frequencies of all the audio
subsystem clocks seem to be same anyway:

# cat /sys/kernel/debug/clk/clk_summary
    ...
    fout_epll                   0           0            192000000

So there might be some other difference I'm overlooking.
