This is v2 of the series to add support for the Allegro DVT H.264 encoder found in the EV family of the Xilinx ZynqMP platform. See v1 [0] of the patch series for a description of the hardware. I fixed the handling of frames with various sizes and driver is now able to encode H.264 video in the baseline profile up to 1920x1080 pixels. I also addressed the issues reported by the kbuild robot for the previous series, implemented a few extended controls and changed the interface to the mcu to follow the register documentation rather than the downstream driver implementation. I would especially appreciate feedback to the device tree bindings and the overall architecture of the driver. The driver still only works with the vcu-firmware release 2018.2. I am not yet sure how to address the different firmware versions, because in addition to the mailbox sizes, there are also changes within the messages themselves. I also did not address the integration with the xlnx-vcu driver, yet.
