Hans de Goede 33a43f6247 ACPI: x86: Add ACPI_QUIRK_UART1_SKIP for Lenovo Yoga Book yb1-x90f/l ... [ Upstream commit f91280f358 ] The Lenovo Yoga Book yb1-x90f/l 2-in-1 which ships with Android as Factory OS has (another) bug in its DSDT where the UART resource for the BTH0 ACPI device contains "\\_SB.PCIO.URT1" as path to the UART. Note that is with a letter 'O' instead of the number '0' which is wrong. This causes Linux to instantiate a standard /dev/ttyS? device for the UART instead of a /sys/bus/serial device, which in turn causes bluetooth to not work. Similar DSDT bugs have been encountered before and to work around those the acpi_quirk_skip_serdev_enumeration() helper exists. Previous devices had the broken resource pointing to the first UART, while the BT HCI was on the second UART, which ACPI_QUIRK_UART1_TTY_UART2_SKIP deals with. Add a new ACPI_QUIRK_UART1_SKIP quirk for skipping enumeration of UART1 instead for the Yoga Book case and add this quirk to the existing DMI quirk table entry for the yb1-x90f/l . This leaves the UART1 controller unbound allowing the x86-android-tablets module to manually instantiate a serdev for it fixing bluetooth.
