I should tell you that this PR will never get merged as it stands because it targets rpi-6.12.y, which is now frozen except for bug fixes. rpi-6.18.y will be the source of the next released kernel, and PRs adding new features should be submitted against it.

You'll need to rebase/cherry-pick your changes onto a local 6.18 branch, then force push it to GitHub and change the base branch by editing the PR (click the pencil icon labelled "Edit title").

OK,thanks,rpi-6.18.y can use module 4B?

[pelwell]

Here are some other things that I think will need to be changed before we consider merging this:

1. Please also add CONFIG_DRM_PANEL_TDO_DSI_V1=m to the other 4 defconfig files - arch/arm/configs/bcmrpi_defconfig, arch/arm/configs/bcm2709_defconfig, arch/arm64/configs/bcm2711_rt_defconfig and arch/arm64/configs/bcm2712_defconfig.
2. Please split the code into 3 commits:

• one for the .c code, Kconfig and module Makefile changes,
• one for the overlay, README and dts Makefile changes, and
• one for the _defconfig changes.

rpi-6.18.y can use module 4B?

I don't understand your question - please ask it another way.
