Subject: [PATCH 0/3] Enable JPEG Encoder on RK3566/RK3568

Hello,

the following series adds support for and enables the hardware JPEG
encoder on the RK3566 and RK3568 line of SoCs by Rockchip.

The JPEG encoder is its own little Hantro instance with seemingly just
the encode functionality.

The first patch modifies the bindings with a new compatible, and adds
the ability to just have a vepu interrupt without a vdpu interrupt.

The second patch makes the actual driver changes to support this variant.

The third and final patch makes the necessary device tree changes for
the rk356x device tree file to add both the node for the encoder and
its MMU.

The series has been tested on a PINE64 Quartz64 Model A with an RK3566
SoC using GStreamer.

Regards,
Nicolas Frattaroli
