dt-bindings: mfd: syscon: Allow syscon compatible for mediatek,mt7981-topmisc

2026-01-22T14:23:34Z

Commit a95419ff9f21 ("dt-bindings: mfd: syscon: Add mt7981-topmisc") added the mediatek,mt7981-topmisc compatible to the `select` block which is used only for compatibility with older dtschema, but did not add it in the actual block allowing to specify the "syscon" fallback compatible, which is required for such node to do anything meaningful in the end. Add the mediatek,mt7981-topmisc compatible in the right list to allow specifing compatible = "mediatek,mt7981-topmisc", "syscon" in the relevant devicetree node.

dt-bindings: mfd: syscon: Document the GPR syscon for the NXP S32 SoCs

2026-01-22T14:22:42Z

The NXP S32 SoCs have a GPR region which is used by a variety of drivers. Some examples of the registers in this region are: * DDR_PMU_IRQ * GMAC0_PHY_INTF_SEL * GMAC1_PHY_INTF_SEL * PFE_EMACS_INTF_SEL * PFE_COH_EN * PFE_PWR_CTRL * PFE_EMACS_GENCTRL1 * PFE_GENCTRL3 Use the syscon interface to access these registers.

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.

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.
