[v5,0/3] Enable JPEG Encoder on RK3566/RK3568

Hello,

this is v5 of my RK356x JPEG encoder patch set. It enables the Hantro
hardware encoder of the RK3566 and RK3568 line of SoCs, with JPEG being
the only format the driver currently supports encoding for.

The first patch adds a new binding, the rockchip,rk3568-vepu binding, to
describe this kind of hardware. The reason for going with a new binding
instead of modifying the vpu binding as the previous versions did is
that the vpu binding is getting quite long, and Ezequiel Garcia suggested
(on IRC) that we could document encoder only instances in their own
binding. This makes sense to me, especially considering that RK3588 will
have more Hantro instances like this to document.

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

Changes in v5:
 - rename rockchip-vepu.yaml to rockchip,rk3568-vepu.yaml
 - fix #address-cells/#size-cells in bindings example
 - fix indentation in bindings example

Changes in v4:
 - bindings: move vepu to its own binding, also add it to MAINTAINERS
 - driver: rename a stray rk3568_jpeg_enc_codec_ops to
   rk3568_vepu_codec_ops
 - devicetree: remove interrupt-names property
 - rebase onto linux-next

Changes in v3:
 - bindings: change consts to an enum
 - bindings: add check to make sure devices with a -vepu compatible only
   have the vepu interrupt

Changes in v2:
 - rename compatible as it's not JPEG only
 - rename device tree nodes as it's not JPEG only
 - reword commits as it's not JPEG only
 - get rid of a whole bunch of redundant struct definitions, as, you
   guessed it, it's not JPEG only
