[PATCH] ASoC: tlv320aix31xx: Add ACPI match for Lenovo 100S

[Bastien Nocera]

The Lenovo 100S netbook has a codec controller for which there is a
driver, but doesn't know how to access the device. This adds the
necessary ACPI table for the driver to find the device.

Device (TTLV)
{
    Name (_ADR, Zero)  // _ADR: Address
    Name (_HID, "10TI3100")  // _HID: Hardware ID
    Name (_CID, "10TI3100")  // _CID: Compatible ID
    Name (_DDN, "TI TLV320AIC3100 Codec Controller ")  // _DDN: DOS Device Name
    Name (_UID, One)  // _UID: Unique ID

An ACPI identifier that actually bears some resemblance to the name of
the part, will wonders never cease!  :)

It's not a legit ACPI id but at least it's consistent with other BIOS. I 
see the same in a couple of DSDT I extracted. it'd be curious to see the 
schematics if you have them to help progress with Baytrail-CR support.

It's in the right form at least, dunno if TI actually registered 10TI
properly or not though.

The PNP ID for TI is TXN
The ACPI ID is TXNW
TI's PCI ID is 0x104C.

so nope, none of the legit vendor IDs match 10TI, which doesn't follow 
the rules... No one seems to care in the BIOS world though, it's 
becoming a lost cause.

The DSDT for that device is at:

Applied "ASoC: tlv320aix31xx: Add ACPI match for Lenovo 100S" to the asoc tree

[Mark Brown]

The patch

   ASoC: tlv320aix31xx: Add ACPI match for Lenovo 100S

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
