2021-04-15 | media: meson-ge2d: fix rotation parameters | Neil Armstrong | |
With these settings, 90deg and 270deg rotation leads to inverted vertical, fix them to have correct rotation.

2020-12-07 | media: meson: Add M2M driver for the Amlogic GE2D Accelerator Unit | Neil Armstrong | |
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] Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> |
