[PATCH v3 0/3] dt-bindings: mfd: syscon: Tighten checks

[Krzysztof Kozlowski]

Changes in v3:
- Drop patch #2:
  dt-bindings: mfd: syscon: Drop unneeded case for syscon + simple-mfd
- Bump dtschema requirement
- Link to v2: https://patch.msgid.link/20260608-n-dt-bindings-simple-bus-syscon-v2-0-0203e6c249dc@oss.qualcomm.com

Changes in v2:
1. New patches #2 and #3
1. Add missing part of patch #1, thus not adding Rob's Ack.

I tested dt_binding_check and dtbs_check for arm, arm64 and riscv and I
think I did not introduce new dtbs_check warnings. Old code anyway has
multiple abuses of syscon, thus tricky to judge for arm at least.

Best regards,
Krzysztof
