media: meson: Add M2M driver for the Amlogic GE2D Accelerator Unit
The GE2D is a 2D accelerator with various features like configurable
blitter with alpha blending, frame rotation, scaling, format conversion
and colorspace conversion.
The driver implements a Memory2Memory VB2 V4L2 streaming device permitting:
- 0, 90, 180, 270deg rotation
- horizontal/vertical flipping
- source cropping
- destination compositing
- 32bit/24bit/16bit format conversion
This adds the support for the GE2D version found in the AXG SoCs Family.
The missing features are:
- Source scaling
- Colorspace conversion
- Advanced alpha blending & blitting options
Is passes v4l2-compliance:
SHA: ea16a7ef13a902793a5c2626b0cefc4d956147f3, 64 bits, 64-bit time_t
[hverkuil: add missing linux/bitfield.h include]
