@pelwell , I have fixed review comments and updated PR.

That's much better. If you can make three more changes I'll merge it:

1. The additions to the _defconfig files are correct but not on the expected lines. For each of those files, run "make ARCH=arm savedefconfig" (or arm64) which will create a file called "defconfig". Copy that over the _defconfig in arch/... .
2. There are 4 lines which are made very long because of trailing comments. Put the comments on the lines above if you must have them.
3. Split the changes into three separate commits:
   • one for the driver, Kconfig and Makefile (the changes in sound/soc/bcm) - use this commit message
   • one for the defconfig changes ("configs: Enable DACBERRY400")
   • one for the overlay ("overlays: Add dacberry400").

Those look good - just the defconfig commit now.

@pelwell , Pushed defconfig commit. Please check.

Any reason this couldn't have been done with a simple/graph sound card DT overlay?

Give me a PR with equivalent functionality and I'll use it instead.
