Subject: DRV260x: Support ACPI-enumerated devices
Date: Thu, 12 Feb 2026 01:46:50 +0200 [thread overview]
Message-ID: <20260211235902.4156624-1-jekhor@gmail.com> (raw)
Lenovo Yoga Book YB1-X90 and YB1-X91 tablets use haptics controllers
DRV2604L. The X91 (Windows tablet) uses ACPI to define its configuration,
such as I2C address and GPIO connections. The X90 (Android tablet)
doesn't have it in the ACPI, but the device may be defined as an
i2c_board in the x86-android-tablets driver.
To support these variants, add an ACPI matching table and add additional
I2C IDs to the I2C matching table (the driver supports DRV2604(L),
DRV2605(L) devices).
Also, add verification of the device ID on start, implement a timeout
for waiting for effect playback, and fix the non-working suspend in case
the 'vbat' regulator doesn't exist in the system.
