drm: sun4i: de33: mixer: add mixer configuration for the H616

2025-06-02T07:59:10+00:00

The H616 (and related SoC packages sharing the same die) carry the new DE33 display engine. Add the mixer configuration and a compatible string for the H616 to the mixer.

drm: sun4i: de33: vi_scaler: add Display Engine 3.3 (DE33) support

2025-06-02T07:59:10+00:00

The vi_scaler appears to be used in preference to the ui_scaler module for hardware video scaling in the DE33. Enable support for this scaler.

drm: sun4i: de33: mixer: add Display Engine 3.3 (DE33) support

2025-06-02T07:59:09+00:00

The DE33 is a newer version of the Allwinner Display Engine IP block, found in the H616, H618, H700 and T507 SoCs. DE2 and DE3 are already supported by the mainline driver. Notable features (from the H616 datasheet and implemented): - 4096 x 2048 (4K) output support Other features (implemented but not in this patchset): - AFBC ARM Frame Buffer Compression support - YUV pipeline support The DE2 and DE3 engines have a blender register range within the mixer engine register map, whereas the DE33 separates this out into a separate display group, and adds a top register map. The DE33 also appears to remove the global double buffer control register, present in the DE2 and DE3. Extend the mixer to support the DE33.

drm: sun4i: de2/de3: use generic register reference function for layer configuration

Use the new blender register lookup function where required in the layer commit and update code.

drm: sun4i: de2/de3: add generic blender register reference function

2025-06-02T07:57:18+00:00

The DE2 and DE3 engines have a blender register range within the mixer engine register map, whereas the DE33 separates this out into a separate display group. Prepare for this by adding a function to look the blender reference up, with a subsequent patch to add a conditional based on the DE type.

drm: sun4i: de2/de3: refactor mixer initialisation

2025-06-02T07:57:17+00:00

Now that the DE variant can be selected by enum, take the oppportunity to factor out some common initialisation code to a separate function.

drm: sun4i: de2/de3: add mixer version enum

2025-06-02T07:57:17+00:00

The Allwinner DE2 and DE3 display engine mixers are currently identified by a simple boolean flag. This will not scale to support additional DE variants. Convert the boolean flag to an enum.
