> 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.
