[PATCH 0/7] media: verisilicon: Add RK3588 VPU720 JPEG decoder

[Sascha Hauer]

This series adds support for the RK3588 JPEG/MJPEG hardware decoder, the
VPU720. This series adds it to the hantro driver, along with three fixes
to the hantro core that came out of the work.

Patches 1-3 are independent of the new decoder and stand on their own. A
codec ->run() that fails currently leaves an armed watchdog behind that
later aborts an unrelated job, leaks the pm_runtime reference and the
clocks, and never completes the control handler object bound to the
media request, so the request stays queued until userspace closes it.
Patch 3 makes V4L2_EVENT_EOS subscribable; hantro queues the event in
three places but no application can ask for it.

Patches 4-7 add the decoder itself: the binding, the driver, a minimum
sizeimage for the coded queue, and the DT node.

Unlike the other hantro en/decoders the VPU720 works as a stateful
decoder - userspace hands it a whole frame and never looks inside the
bitstream. The driver parses the JPEG header on the CPU, builds the
quantisation and Huffman tables into a DMA side buffer and programs the
hardware from there.

Patch 6 enforces a minimum frame size to the coded queue for the JPEG
decoder path. This is necessary here as userspace doesn't know how large
a frame can get, but the decoder needs a full frame to work. In my
Gstreamer tests Gstreamer came up with buffers that were too small to
take a full frame at higher resolutions (> 1080p). That is expensive of
course, 16 MiB for a 4k image.

Tested on a Radxa Rock-5t board
