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 Nicolas Frattaroli (3): media: dt-binding: media: Add rk3568-vepu binding media: hantro: Add support for RK356x encoder arm64: dts: rockchip: Add Hantro encoder node to rk356x .../bindings/media/rockchip,rk3568-vepu.yaml | 69 +++++++++++++++++++ MAINTAINERS | 1 + arch/arm64/boot/dts/rockchip/rk356x.dtsi | 20 ++++++ drivers/staging/media/hantro/hantro_drv.c | 1 + drivers/staging/media/hantro/hantro_hw.h | 1 + .../staging/media/hantro/rockchip_vpu_hw.c | 25 +++++++ 6 files changed, 117 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/rockchip,rk3568-vepu.yaml -- 2.36.1
