DMA ops are a helper for architectures and not for drivers to override the DMA implementation. Unfortunately driver authors keep ignoring this. Make the fact more clear by renaming the symbol to ARCH_HAS_DMA_OPS and having the two drivers overriding their dma_ops depend on that. These drivers should probably be marked broken, but we can give them a bit of a grace period for that.

This is the 6th Gen Intel Image Processing Unit, found in Intel SoCs
|
|
and used for capturing images and video from camera sensors.
|
|
|
|
To compile this driver, say Y here! It contains 2 modules -
|
|
intel_ipu6 and intel_ipu6_isys.
