The "interrupts" property in the example looks weird: - The type is not in the last cell, - Level interrupts don't work well with gpio-keys, as they keep the interrupt asserted as long as the key is pressed, causing an interrupt storm.

The if/then schema for 'data-lanes' doesn't work as 'compatible' is at a different level than 'data-lanes'. To make it work, the if/then schema would have to be moved to the top level and then whole hierarchy of nodes down to 'data-lanes' created. I don't think it is worth the complexity to do that, so let's just drop it. The error in this schema is masked by a fixup in the tools causing the 'allOf' to get overwritten. Removing the fixup as part of moving to json-schema draft 2019-09 revealed the issue: Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.example.dt.yaml: mipi-csi@30750000: ports:port@0:endpoint:data-lanes:0: [1] is too short From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.yaml Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.example.dt.yaml: mipi-csi@32e30000: ports:port@0:endpoint:data-lanes:0: [1, 2, 3, 4] is too long From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.yaml The if condition was always true because 'compatible' did not exist in 'endpoint' node and a non-existent property is true for json-schema.

While node-states-8.dot has two digraphs, the dot(1) command can not properly handle multiple graphs in a DOT file and the kernel-doc page at https://www.kernel.org/doc/html/latest/admin-guide/blockdev/drbd/figures.html fails to render the graphs. It turned out that the digraph of node_states can be removed. Quote from Joel's reflection: On reflection, the digraph node_states can be removed entirely. It is too basic to contain any useful information. In addition it references "ioctl_set_state". The ioctl configuration interface for DRBD has long been removed. In fact, it was never in the upstream version of DRBD. Remove node_states and rename the DOT file peer_states-8.dot. Suggested-by:Joel Colledge <joel.colledge@linbit.com> Acked-by:
