[PATCH v1 2/2] ASoC: Intel: soc-acpi-cht: Add Lenovo Yoga Book entries

From: Yauhen Kharuzhy

Date: Tue Feb 17 2026 - 18:14:01 EST


Lenovo Yoga Book YB1-X91 device uses a Cherry Trail SoC and has a valid
ACPI DSDT entry for the RT5677 codec. This entry has some non-standard
resource definitions, such as jack detection chip information, and
hardware has some additional GPIO controls so use 'cht-yogabook'
for the driver name instead of some default (like 'cht-bsw-rt5677').

Lenovo Yoga Book YB1-X90 device (Android version of the tablet) has the
same hardware configuration but lacks a valid ACPI DSDT entry for the
codec. To match this device, extend the existing quirk designated for the
Lenovo Yoga Tab 3 Pro YT3-X90 and make it more generic: select a matched
machine using the dmi_check_system() quirk mechanism.
