ASoC: tlv320aix31xx: Add ACPI match for Lenovo 100S
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 Signed-off-by: Bastien Nocera <hadess@hadess.net> Tested-by: Jan Schmidt <jan@centricular.com> Signed-off-by: Mark Brown <broonie@kernel.org>
