[PATCH v4 0/2] Touch Bar DRM driver for x86 Macs

[Aditya Garg <gargaditya08@live.com>]

The following patch series aims to add support for the DRM mode of the
Touch Bar found on x86 Macs. The DRM mode enables the Touch Bar to act
as a second display, just like macOS.

The first patch adds emulation helper from XRGB8888 to BGR888 which is
needed by this device and the driver.

The second patch is the main DRM driver, required for the DRM mode.
Currently, only T2 Macs are supported.

Currently, a daemon named tiny-dfr [1] by Asahi Linux supports the
Touch Bar in this mode by displaying the Function and Media keys.
More such daemons can be made with more customisation in the future.
