Subject: [PATCH v3 0/4] media: meson: Add support 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
Dependencies:
- Patches 1-3: None
- Patch 4: https://lkml.kernel.org/r/20200915124553.8056-1-narmstrong@baylibre.com (applied for 5.11)
Changes since v2:
- removed error check in and after get_frame()
- moved the v4l2_file_operations lower in the code to avoid adding vidioc_setup_cap_fmt on top
- removed all memcpy of pix_fmt
- simplified & fixed ge2d_start_streaming
- added local buffer type check in vidioc_g_selection instead of using get_frame error
- removed impossible <0 rectangle check, fixed error string
- added comment on condition after V4L2_CID_ROTATE
Changes since v1:
- Rebased on v5.10-rc1
