- const: syscon
dt-bindings: arm: stm32: add simple-mfd compatible for tamp node The stm32mp1 TAMP (Tamper and backup registers) does tamper detection and features 32 backup registers that, being in the RTC domain, may survive even with Vdd switched off. This makes it suitable for use to communicate a reboot mode from OS to bootloader via the syscon-reboot-mode binding. Add a "simple-mfd" to support probing such a child node. The actual reboot mode node could then be defined in a board.dts or fixed up by the bootloader.

dt-bindings: Add missing 'additionalProperties: false' Setting 'additionalProperties: false' is frequently omitted, but is important in order to check that there aren't extra undocumented properties in a binding. Ideally, we'd just add this automatically and make this the default, but there's some cases where it doesn't work. For example, if a common schema is referenced, then properties in the common schema aren't part of what's considered for 'additionalProperties'. Also, sometimes there are bus specific properties such as 'spi-max-frequency' that go into bus child nodes, but aren't defined in the child node's schema. So let's stick with the json-schema defined default and add 'additionalProperties: false' where needed. This will be a continual review comment and game of wack-a-mole.
