Core OF driver code, e.g. drivers/of/: + patches are reviewed and applied by DT maintainers. + +2. Devicetree bindings: + patches are reviewed by DT maintainers, but should be applied by subsystem + maintainers except in certain cases. See also *For kernel maintainers* in + Documentation/devicetree/bindings/submitting-patches.rst. + +3. DTS and drivers: + DT maintainers might provide comments, but review is generally not expected. + DTS must pass schema checks (dtbs_check) or at least do not add any + new warnings. + +Patchwork +~~~~~~~~~ + +Devicetree maintainers review patches using Patchwork, so the current status of +a patch can be checked there. For typical driver submissions, Patchwork +receives the entire patch set, but only a few patches are usually Devicetree +bindings that are reviewed by DT maintainers. + +Explanation of Patchwork statuses: + + - **New**: Not yet processed by the automation toolset. + - **Needs ACK**: Waiting for review by DT maintainers. + - **Handled Elsewhere**: Non-DT patch; not being reviewed here. + - **RFC**: Patch was likely ignored because it was an incomplete RFC. + - **Changes Requested**: Patch was reviewed and DT maintainers expect changes. + - **Accepted**: Patch was reviewed and applied by DT maintainers to their tree. + - **Not Applicable**: Patch was reviewed and is likely in good shape, with a + *Reviewed-by* or *Acked-by* tag provided, but DT maintainers expect someone + else to apply it. + +Patch Re-review and Pinging +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Due to the high volume of email traffic, Devicetree maintainers do not read +every email they receive and instead rely on Patchwork during the review +process. They also often skip patches that have already been reviewed. + +As a result, maintainers might miss: + +1. Questions about already reviewed patches. +2. Pings, for example when a patch has been reviewed by DT maintainers but has + not been picked up by subsystem maintainers. + +Such cases can be addressed by: + +1. Pinging DT maintainers on the IRC channel. +2. Dropping the DT maintainer’s *Acked-by* or *Reviewed-by* tag when sending a new + version of the patch set, together with an explanation in the patch + changelog describing why the tag was removed and what is expected from DT + maintainers. + -- cgit v1.3.1
