From a5cb0695c5f0ac2ab0cedf2c1c0d75826cb73448 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 1 Mar 2023 11:04:35 +0100 Subject: ACPI: x86: Add skip i2c clients quirk for Acer Iconia One 7 B1-750 The Acer Iconia One 7 B1-750 is a x86 tablet which ships with Android x86 as factory OS. The Android x86 kernel fork ignores I2C devices described in the DSDT, except for the PMIC and Audio codecs. As usual the Acer Iconia One 7 B1-750's DSDT contains a bunch of extra I2C devices which are not actually there, causing various resource conflicts. Add an ACPI_QUIRK_SKIP_I2C_CLIENTS quirk for the Acer Iconia One 7 B1-750 to the acpi_quirk_skip_dmi_ids table to woraround this. The DSDT also contains broken ACPI GPIO event handlers, disable those too. Signed-off-by: Hans de Goede Signed-off-by: Rafael J.
