    Subject[PATCH 0/3] Touch Bar and Keyboard backlight driver for Intel Macs
    Date
    Greetings from t2linux!

    2 years ago an attempt was made to send the driver for the Touch Bar on
    MacBook Pros by Ronald Tschalär [1].

    Due to some issues pointed out by the maintainers upstream, unfortunately
    it didn't make it upstream. Now we at t2linux [2] have addressed those
    issues in this patchset and also improved the touchbar driver for the T2
    Macs. We also have added a new driver for keyboard backlight support on
    T2 MacBooks with Magic Keyboard.

    The first 2 patches of this patchset are the ones sent by Ronald before,
    with the issues addressed as pointed out in [1].

    The third patch introduces a new driver, apple-magic-backlight, which adds
    support for keyboard backlight on T2 MacBooks with the Magic Keyboard.

    Note: Apart from these drivers, for the T2 Macs, an additional driver
    shall be required to communicate with the T2 Security Chip, as the Touch
    Bar, the internal keyboard, trackpad, camera, ambient light sensor,
    headphone controls, and NCM Ethernet are accessed through a USB VHCI
    created with DMA channels to the "T2 Bridge Controller" 106b:1801 PCI
    device. A work in progress linux driver called apple-bce [3], or USB
    device passthrough to a Linux VM guest on a Windows host with Apple
    Bootcamp drivers can be used to get Linux these USB devices working and
    test these patches.
