From: Conor Dooley <conor.doo...@microchip.com> The reset and poweroff features of the syscon were originally added to top level, which is a valid path for a syscon subnode. Subsequently a reorganisation was carried out while implementing NUMA in which the subnodes were moved into the /soc node. As /soc is a "simple-bus", this path is invalid, and so dt-validate produces the following warnings:
/stuff/qemu/qemu.dtb: soc: poweroff: {'value': [[21845]], 'offset': [[0]], 'regmap': [[4]], 'compatible': ['syscon-poweroff']} should not be valid under {'type': 'object'} From schema: /home/conor/.local/lib/python3.9/site-packages/dtschema/schemas/simple-bus.yaml /stuff/qemu/qemu.dtb: soc: reboot: {'value': [[30583]], 'offset': [[0]], 'regmap': [[4]], 'compatible': ['syscon-reboot']} should not be valid under {'type': 'object'} From schema: /home/conor/.local/lib/python3.9/site-packages/dtschema/schemas/simple-bus.yaml Move the syscon subnodes back to the top level and silence the warnings.
