This series of patches adds the support of v4l2 2D blitter driver for
STMicroelectronics SOC.
version 2:
- Renamed to STI_BDISP, inserted the sti directory.
- Reworked the cropping vs selection API.
- Used additional v4l2_m2m helpers and fops.
- Dropped pixel format description.
- Fixed memory release issue.
version 1:
- Initial submission.
The following features are supported and tested:
- Color format conversion (RGB32, RGB24, RGB16, NV12, YUV420P)
- Copy
- Scale
- Flip
- Deinterlace
- Wide (4K) picture support
- Crop
This driver uses the v4l2 mem2mem framework and its implementation was largely
inspired by the Exynos G-Scaler (exynos-gsc) driver.
The driver is mainly implemented across two files:
- bdisp-v4l2.c
- bdisp-hw.c
bdisp-v4l2.c uses v4l2_m2m to manage the V4L2 interface with the userland.
It calls the HW services that are implemented in bdisp-hw.c.
The additional bdisp-debug.c file manages some debugfs entries.
