[PATCH v2 0/8] Baytrail followup

[PATCH v2 0/8] Baytrail followup

[Pierre-Louis Bossart]

Thanks to Mark for merging most of the patches in the first batch.
Resending update for patches that where not merged.
No additional functionalitity, only correction in first patch to refer to 
correct SHA1 and copy/paste fixes in bytcr_rt5651 machine driver

Acknowledgements:
Keyon Jie for his MinnowBoard validation
Francisco Mendez for his help with the MCLK and jack detection
Jack Yu and Bard Liao for their codec support

Known issues: 
noise on startup when using speakers

Once this batch is merged, the following updates will be provided:
MCLK support to fix noise issues
BYT-CR fixes
jack detection

Jack Yu (1):
  ASoC: rt5640: add ASRC support

Jorge Fernandez Monteagudo (1):
  ASoC: Intel: Atom: Add support for HP ElitePad 1000 G2

Pierre-Louis Bossart (6):
  ASoC: Intel: fix ACPI probe regression with Atom DPCM driver
  ASoC: Intel: add bytct-rt5651 machine driver
  ASoC: intel: boards: add card for MinnowBoard I2S access
  ASoC: Intel: bytcr-rt5640: enable ASRC
  ASoC: Intel: bytcr_rt5640: fixup DAI codec_name with HID
  ASoC: Intel: Atom: add support for RT5642

[PATCH v2 1/8] ASoC: Intel: fix ACPI probe regression with Atom DPCM driver

[Pierre-Louis Bossart]

The commit 95f098014815b330838b1173d3d7bcea3b481242
"ASoC: Intel: Move apci find machine routines"

introduced a regression in ACPI probe of the DPCM driver.
Fix by conditionally compiling sst-acpi when the DPCM driver
is not selected

[PATCH v2 7/8] ASoC: Intel: Atom: add support for RT5642

[Pierre-Louis Bossart]

The machine driver is not loaded when the BIOS uses the 10EC5642
_HID. Add it to the white list of known _HIDs, codec_name is
already taken care of by previous commit

Tested on Asus T100TAF.

For future reference if you're sending a bunch of unrelated patches it's
easier to send them separately to make it clear that there are no
dependencies.

I'm wondering how this is going to get loaded (I don't see what creates
the platform device) and how we handle systems with a CODEC connected on
the expansion headers?

Will do. It was convenient for me since I could keep track of a single 
patch list and test the same kernel on multiple Baytrail platforms but 
yes they are not related.

Good question.

On the minnowmax we can't use the default firmware since users may use 
different codecs and the pins may be used for different non-audio 
functions and lures. The firmare team also didn't want to maintain tons 
of options. Generating the image from source is possible but it requires 
a fair amount of work to keep track of unrelated non-audio firmware updates.

To solve this audio is disabled by default, and we have an EFI 
application loaded by the startup.nsh file that sets the relevant codec 
information in the SSDT table so that you can swap codec cards at will. 
The EFI application will be open-sourced so that additional codecs can 
be added as needed with changes in the ASL code. The whole thing was 
tested with experimental releases in three different setups for now but 
will be formally released next month.

On probe the sst_acpi part checks for the presence of known codecs and 
registers the platform driver. For the case where no codec is present I 
just added an entry at the end of the table that always works (checks 
for an SOC-side HID) and is selected if no other codec was found. I need 
to add this patch and submit it, forgot to add it in this batch.

Applied "ASoC: Intel: add bytct-rt5651 machine driver" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: add bytct-rt5651 machine driver

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Sets the relevant codec information by...?

Can we punt on this until we've got the rest of the infrastructure to
look at?  I'd feel safer and it sounds like it's going to need some
manual hacking to get working anyway until the other bits are lined up.

exposing devices and dependencies, setting the _HID, codec I2C address, 
Gpio lines, DSD properties if needed. Nothing new compared to a normal 
DSDT table except that you only add the audio-related information yourself.

that's fine, i will provide more documentation to explain the steps 
later this month. The 'infrastructure' isn't that bad really - and since 
the SSDT update application is open-source for once you can't blame the 
BIOS if your audio doesn't work :-)
