From c69fec50ec2e3aeea46b13235b72d9d5a1bf095a Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 1 Apr 2023 17:07:37 +0200 Subject: platform/x86: x86-android-tablets: Add Lenovo Yoga Book X90F/L data The Lenovo Yoga Book X90F/L is a x86 ACPI tablet which ships with Android x86 as factory OS. Its DSDT contains a bunch of I2C devices which are not actually there, causing various resource conflicts. Enumeration of these is skipped through the acpi_quirk_skip_i2c_client_enumeration(). Add support for manually instantiating the I2C + other devices which are actually present on this tablet by adding the necessary device info to the x86-android-tablets module.
