dt-bindings: mfd: khadas,mcu: Drop type reference from "fan-supply"

2026-06-24T13:48:09+00:00

"fan-supply" already has a type and shouldn't have a type $ref. Drop the $ref to fix the warning. Fixes: 39dd85d9246e ("dt-bindings: mfd: khadas: Add new compatible for Khadas VIM4 MCU") Link: https://patch.msgid.link/20260624133643.4146351-1-robh@kernel.org Signed-off-by: Rob Herring (Arm)

dt-bindings: mfd: syscon: Revert renesas,r9a08g046-lvds-cmn

2026-06-17T10:33:12+00:00

Revert commit 51284d8b1dbc ("dt-bindings: mfd: syscon: Document the LVDS_CMN syscon for the RZ/G3L") because it is completely not matching reality and clearly incorrect in respect of renesas,r9a08g046-lvds-cmn. It wasn't ever build-tested by author on their DTS, either. The documented renesas,r9a08g046-lvds-cmn compatible clearly disallows any children and simple-mfd fallback, however its only use in original patchset is with simple-mfd and children, so this could have never worked.

dt-bindings: mfd: st,stmpe: Add missing properties for PWM subnode

2026-06-17T10:33:10+00:00

The st,stmpe-pwm binding is already covered by the MFD schema in Documentation/devicetree/bindings/mfd/st,stmpe.yaml. However, the PWM subnode was missing a 'required' properties block. This allowed Device Tree nodes to pass validation even if the 'compatible' string was omitted. This omission could lead to probe failures at runtime. Fix the schema by adding the missing 'required' block.

dt-bindings: mfd: aspeed,ast2x00-scu: Support AST2700 SoC1 pinctrl

2026-06-17T10:32:58+00:00

The AST2700 SoC integrates two interconnected SoC instances, each managed by its own System Control Unit (SCU). Allow the AST2700 SoC1 pin controller to be described as a child node of the SCU by extending the compatible strings accepted by the SCU binding. There is no functional change to the SCU binding beyond permitting the aspeed,ast2700-soc1-pinctrl compatible string.

The SC2730 PMIC provides a different set of regulators than SC2731 and thus requires separate regulator bindings. Allow using them for the "regulators" node.
