Hans de Goede cd8e468efb ACPI: video: Add Dell UART backlight controller detection ... Dell All In One (AIO) models released after 2017 use a backlight controller board connected to an UART. In DSDT this uart port will be defined as: Name (_HID, "DELL0501") Name (_CID, EisaId ("PNP0501") Commit 484bae9e4d ("platform/x86: Add new Dell UART backlight driver") has added support for this, but I neglected to tie this into acpi_video_get_backlight_type(). Now the first AIO has turned up which has not only the DSDT bits for this, but also an actual controller attached to the UART, yet it is not using this controller for backlight control. Add support to acpi_video_get_backlight_type() for a new dell_uart backlight type. So that the existing infra to override the backlight control method on the commandline or with DMI quirks can be used.
