| Subject: [PATCH] usb: musb: da8xx: Remove CPPI 3.0 quirk and methods |
| |
| 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") |
