yep, this works, thanks Takashi. With an additional DMI fix i'll submit
later I get sound on the Dell 5585.

The patch
ASoC: rt5670: Fix GPIO headset detection regression
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

Subject: [PATCH] ASoC: rt5670: Fix GPIO headset detection regression
RT5670 codec driver and its machine driver for Intel CHT assume the
implicit GPIO mapping on the index 0 while BIOS on most devices don't
provide it. The recent commit f10e4bf6632b ("gpio: acpi: Even more
tighten up ACPI GPIO lookups") restricts such cases and it resulted in
a regression where the headset jack setup fails like:
rt5670 i2c-10EC5672:00: ASoC: Cannot get gpio at index 0: -2
rt5670 i2c-10EC5672:00: Adding jack GPIO failed
For fixing this, we need to provide the GPIO mapping explicitly in the
machine driver. Also this patch corrects the string to be passed to
gpiolib to match with the pre-given mapping, too.
Fixes: f10e4bf6632b ("gpio: acpi: Even more tighten up ACPI GPIO lookups")
