    Subject[PATCH 4.10 112/167] usb: musb: da8xx: Remove CPPI 3.0 quirk and methods
    Date
    4.10-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Alexandre Bailon <abailon@baylibre.com>

    commit a994ce2d7e66008381a0b184c73be9ae9b72eb5c upstream.

    DA8xx driver is registering and using the CPPI 3.0 DMA controller but
    actually, the DA8xx has a CPPI 4.1 DMA controller.
    Remove the CPPI 3.0 quirk and methods.

    Fixes: f8e9f34f80a2 ("usb: musb: Fix up DMA related macros")
    Fixes: 7f6283ed6fe8 ("usb: musb: Set up function pointers for DMA")
