Hi all, I'm going to *try* to "write" a driver for the sound card on my new laptop, an asus x205ta.
To be fair I have almost no experience but I'm hoping that all the code is already present and it only needs some adaptations.
I'd expect most of the code to be present, but it's likely some integration is required for differences to HW/BIOS compared to the driver development platform.
The cpu is a intel bay trail z3735f, the sound card is a realtek rt5648 that has the same product Id of the rt5645 (0x6308).
I see in kernel sources:
- the codec driver sound/soc/codecs/rt5645.c
- a baytrail board that uses the rt5640 sound/soc/intel/boards/byt-rt5640.c
- a braswell board that uses the rt5645 sound/soc/intel/boards/cht_bsw_rt5645.c
What do you think? Is it feasible, given a good amount of free-time? :p
Thanks, Michele
So I started.. :) At the end of the email there is the patch.
What I did:
- copied the board file byt-rt5640.c to byt-rt5645.c
- find&replace 5640->5645 in byt-rt5645.c
- added acpi device id to detect the sound card
- added kernel config SND_SOC_INTEL_BYT_RT5645_MACH to select the driver
Nothing works.
But at least the right modules are loaded it seems..

OK, this means the audio DSP and codec devices are present in the BIOS.
And dmesg tells me: [ +1.386847] rt5645 i2c-10EC5648:00: Failed to reguest IRQ: -22 [ +0.000102] rt5645 i2c-10EC5648:00: Fail gpio_request hp_det_gpio [ +0.000094] rt5645 i2c-10EC5648:00: Fail gpio_direction hp_det_gpio
Looks like the codec has no platform data and is failing to get a valid IRQ number. Do you know what IRQ the code is actually requesting as it could be bogus ?

Ok, this means the ADSP FW has been loaded but has failed to boot for some reason. Can you switch on driver dev_dbg() output.

Keyon, could you take a look?

Thank you! In that patch I did a typo:
index 0000000..5bdb56e --- /dev/null +++ b/sound/soc/intel/boards/byt-rt5645.c @@ -0,0 +1,222 @@ +/*
[snip]
+static struct snd_soc_dai_link byt_rt5645_dais[] = {

.name = "Baytrail Audio",.stream_name = "Audio",.cpu_dai_name = "baytrail-pcm-audio",.codec_dai_name = "rt5645-aif1",.codec_name = "i2c-10EC56458:00",here. This must be "i2c-10EC5648:00", but errors remain the same...
The error
[ +0.020845] (NULL device *): ipc: error DSP boot timeout
made me think that I chose the wrong platform/machine because:
- it is stange that device is NULL
- it is strange that dsp doesn't work after loading the firmware.
The NULL device is just a bug in the code. The device should be set prior to any driver messages.
So instead of adapting the boards/byt-rt5640.c I tried to adapt boards/bytcr_rt5640.c that uses .cpu_dai_name = "ssp2-port", .platform_name = "sst-mfld-platform",
I got a "dummy sound card" but no hardware sound card..
There are 2 BYT DSP driver upstream, they are for different HW configurations. Can you stick with boards/byt-rt5640.c for the moment until we can debug further.
I remember that the errors
[ +1.386847] rt5645 i2c-10EC5648:00: Failed to reguest IRQ: -22 [ +0.000102] rt5645 i2c-10EC5648:00: Fail gpio_request hp_det_gpio [ +0.000094] rt5645 i2c-10EC5648:00: Fail gpio_direction hp_det_gpio
remain. Now I don't have access to the laptop, so I cannot post the new errors that showed up, but if you want me to make some experiments, I'll do :)
Ok, lets get the dev_dbg() output enabled for sst-baytrail*.c and we can take it from there.
Thanks
Liam
