This series of patches adds the support of v4l2 2D blitter driver for STMicroelectronics SOC. 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.
