I've also left out some pwm-fan/thermal content; while the board does not ship with a fan the A311D chip should be used with one and I believe the board has a connector to add a fan, but until this is confirmed (and production boards are available) it's best left out.

The v6.3/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers for inclusion in their intermediate git branches in order to be sent to Linus during the next merge window, or sooner if it's a set of fixes. In the cases of fixes, those will be merged in the current release candidate kernel and as soon they appear on the Linux master branch they will be backported to the previous Stable and Long-Stable kernels [2]. The intermediate git branches are merged daily in the linux-next tree [3], people are encouraged testing these pre-release kernels and report issues on the relevant mailing-lists. If problems are discovered on those changes, please submit a signed-off-by revert patch followed by a corrective changeset.
