[PATCH 0/3] Intel-rt5670 updates

[Pierre-Louis Bossart]

Instead of submitting all my patches at ones, I broke them by
platforms/codecs. This series is only for Intel-rt5670 platforms. It
fixes a mistake on the Dell Venue 5585 - corrected with the help from
Realtek and Dell who kindly provided schematics and data sheet
information needed to fix non-working DMIC capture. Since there are
still some reports of non-functional audio on some platforms, I added
quirks that can be changed from the kernel command line (and later
added as DMI-based quirks). The last two patches are minor corrections
to fix ACPI HID naming issues and use a more meaningful card name.

[PATCH 1/3] ASoC: rt5670: refactor DMI quirks and fix Dell Venue settings

[Pierre-Louis Bossart]

Additional checks exposed a mistake in the quirk for the Dell Venue
Pro 5855 (Dmic2 instead of Dmic1). Rather than adding quirk tables,
merge all quirks in a single table and use flags to differentiate
platforms.  Also add a parameter override to help support additional
platforms using this codec

[PATCH 2/3] ASoC: Intel: cht_bsw_rt5672: use actual HID in suspend/resume

[Pierre-Louis Bossart]

The code scans all components looking for the default name
i2c-10EC5670:00, which of course doesn't work in platforms
where the BIOS uses a different HID such as Dell 5585

Since we already have the correct information available, just
use the actual codec name and length.

[PATCH 3/3] ASoC: Intel: cht_bsw_rt5672: fix card name

[Pierre-Louis Bossart]

For now reason the current card name is a ridiculous
'cherrytrailcraudio'. This isn't very useful or self-explanatory,
change to driver name cht-bsw-rt5672.

One bonus by this change would be to avoid inconsistent names by the
driver's name string size.  Since it's 16 bytes including \0, the
name is shortened as cherrytrailcrau or such in some fields.  With the
new name this shouldn't happen.

In anyway,

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
