In preparation for the RGA3 add support for external iommus. This is a transition step to just disable the RGA2 specific mmu table setup code. Currently a simple rga_hw struct field is used to set the internal iommu. But to handle the case of more sophisticated detection mechanisms (e.g. check for an iommu property in the device tree), it is abstracted by an inline function.

This is a v4l2 driver for Rockchip SOC RGA 2d graphics accelerator.
|
|
Rockchip RGA is a separate 2D raster graphic acceleration unit.
|
|
It accelerates 2D graphics operations, such as point/line drawing,
|
|
image scaling, rotation, BitBLT, alpha blending and image blur/sharpness.
|
|
|
|
To compile this driver as a module choose m here.
