Add a KMS driver for the Ingenic JZ47xx family of SoCs.In the drm world we include the revision notes in the changelog.
This driver is meant to replace the aging jz4740-fb driver.
This driver does not make use of the simple pipe helper, for the reason
that it will soon be updated to support more advanced features like
multiple planes, IPU integration for colorspace conversion and up/down
scaling, support for DSI displays, and TV-out and HDMI outputs.

v2: - Remove custom handling of panel. The panel is now discovered using
the standard API.
- Lots of small tweaks suggested by upstream
v3: - Use devm_drm_dev_init()
- Update compatible strings to -lcd instead of -drm
- Add destroy() callbacks to plane and crtc
- The ingenic,lcd-mode is now read from the bridge's DT node
v4: Remove ingenic,lcd-mode property completely. The various modes are now
deduced from the connector type, the pixel format or the bus flags.
v5: - Fix framebuffer size incorrectly calculated for 24bpp framebuffers
- Use 32bpp framebuffer instead of 16bpp, as it'll work with both
16-bit and 24-bit panel
- Get rid of drm_format_plane_cpp() which has been dropped upstream
- Avoid using drm_format_info->depth, which is deprecated.
So I did this when I applied it to drm-misc-next.
Fixed a few trivial checkpatch warnings about indent too.
There was a few too-long-lines warnings that I ignored. Fixing them
would have hurt readability.
I assume you will maintain this driver onwards from now.
Please request drm-misc commit rights (see
You will need a legacy SSH account.
And you should familiarize yourself with the maintainer-tools:
For my use I use "dim update-branches; dim apply; dim push
So only a small subset i needed for simple use.
