dt-bindings: mfd: syscon: Add mt7981-topmisc

2025-11-20T15:40:54Z

This hardware block amongst other things includes a multiplexer for a high-speed Combo-Phy.

dt-bindings: mfd: Document syscons falling back to atmel,sama5d2-sfrbu

2025-11-20T14:16:45Z

The sfrbu on both sama7g5 and sama6d65 both fall back to sama5d2 in devicetrees, but the former two compatibles were undocumented. Now that syscon.yaml has easy support for multiple soc-specific compatibles, add both of these undocumented devices.

dt-bindings: mfd: Document control-scb and sysreg-scb on pic64gx

2025-11-20T14:16:27Z

On pic64gx these syscons are identical to those on mpfs, and should use a fallback. Add support for multiple fallback compatibles to syscon.yaml with these as the first two users.

dt-bindings: mfd: syscon: Document the control-scb syscon on PolarFire SoC

2025-10-01T09:28:36Z

The "control-scb" region, contains the "tvs" temperature and voltage sensors and the control/status registers for the system controller's mailbox. The mailbox has a dedicated node, so there's no need for a child node describing it, looking the syscon up by compatible is sufficient.

dt-bindings: mfd: syscon: Add mediatek,mt8365-infracfg-nao

2025-05-23T07:49:14Z

The register space described by DT node of compatible mediatek,mt8365-infracfg-nao exposes a variety of unrelated registers, including registers for controlling bus protection on the MT8365 SoC, which is used by the power domain controller through a syscon. Add this compatible to the syscon binding. Signed-off-by: Nícolas F. R. A.
