Hi all, This patch series adds support for the imx8q video encoder and decoder via the VPU block present in imx8q platforms. Currently, support for IMX8QXP and IMX8QM is included. It features decoding for the following formats: - H.264 - HEVC - MPEG4 - MPEG2 - VC1 - VP8 It features encoding for the following formats: - H.264 The driver creates a separate device node for the encoder and decoder. Changelog: v5: - move some definition from imx_vph.h to videodev2.h - remove some unnecessary content - add some documentation descriptions - pass the lateset v4l2-compliance test v4: - redefine the memory-region in devicetree bindings documentation - use v4l2's mechanism to implement synchronize queuing ioctl - remove the unnecessary mutex ioctl_sync - don't notify source change event if the parameters are same as previously established - add flag V4L2_FMT_FLAG_DYN_RESOLUTION to decoder's capture format v3: - don't make vpu device node a simple-bus - trigger probing vpu core in the driver - remove unnecessary vpu core index property v2: - fix dt bindings build error - split driver patch into several parts to avoid exceeding bytes limit Compliance ========== # v4l2-compliance -d
