I see you pulled that one and of_node_put() fix into fixes. Thanks! Can you apply also Sudip's fix for thermal (acked by Lukasz)? I have it my try but since you applied these two already it does not have sense any more.

Even playing a simple wav does not work: $ time aplay -D sysdefault /usr/share/sounds/alsa/Front_Center.wav Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono real 0m1.138s user 0m0.005s sys 0m0.005s This should be ~1.5 seconds so audio is processed faster than expected. So something else besides making the CLKOUT to provide a valid frequency for the codec's master clock is needed. Do you know what's missing in mainline? For instance, I see that the sound/soc/samsung/snow.c ASoC machine driver doesn't have a hw_params but I'm not that familiar with ALSA to know if that makes sense or not. Also, do you know if the "simple-audio-card" can be used instead for snow and peachs as it is used for other Exynos5 boards or a specific ASoC machine driver is really needed for these Chromebooks? Best regards,

Yes, I see the same problem with all the files I tested. >> So something else besides making the CLKOUT to provide a valid frequency >> for the codec's master clock is needed. >> > The $SUBJECT patch actually fix the audio card detection issue, which > was failing because of the missing master clock. > I thought the problem was not a missing master clock, but an invalid clock frequency. Since the error message in the patch change log was: "max98090 7-0010: Invalid master clock frequency" But what I tried to ask was what else was missing to have playback working. >> Do you know what's missing in mainline?

No worries, I was asked in case you had more information. Audio is the only thing that is missing to have all peripherals working correctly with mainline. > Probably we can go back to before "2fad972d45c4" and check that. > Do you mean to revert $SUBJECT and "2fad972d45c4" to see if the bootloader sets this correctly? If I revert both patches then I have no audio at all. >> Also, do you know if the "simple-audio-card" can be used instead for >> snow and peachs as it is used for other Exynos5 boards or a specific >> ASoC machine driver is really needed for these Chromebooks? >> > Not sure, AFAIR, I used machine driver on chromebooks (snow and peach). > Yes, the downstream 3.8 ChromiumOS tree has also a machine driver but I don't see a simple-audio-card in that tree so it seems that predates it.
