This patchset depends on the series "imx8mp: Add media block control"[1] and "i.MX8MP GPC and blk-ctrl"[2] which provide the power driver infrastructure. v1: https://patchwork.linuxtv.org/project/linux-media/list/?series=7443 which can now be marked as superseded Patches [1-3/9] add support for dynamic array control imported from the "Move HEVC stateless controls out of staging"[3] currently under review. Patches [4-7/9] document the driver interfaces, and export its v4l2 custom control to uapi headers. Patches [8/9] adds the v4l2 m2m driver. Patches [9/9] adds the driver to MAINTAINERS. As raised by Laurent, the driver could be located in drivers/media/platform/imx as the dw100 IP can be found on i.MX8MP SoC but the driver design and its hardware integration has not been specialized for i.MX8MP. Hence, the initial driver design rationale was to consider this driver as SoC agnostic. The Vivante DW100 Dewarp Engine, found on i.MX8MP SoC, provides high-performance dewarp processing for the correction of the distortion that is introduced in images produced by fisheye and wide angle lenses. The engine can be used for accelerating scaling, cropping and pixel format conversion operations independently of the dewarping feature.
