dt-bindings: mux: Remove nodename pattern constraints

2026-03-05T02:36:57Z

The nodename pattern in created an unnecessary restriction that forced all mux nodes to be named with the 'mux-controller' prefix. This prevented valid use cases where mux functionality is part of other hardware blocks that should use more specific naming conventions. Remove the $nodename pattern constraints from both the 'select' keyword and the properties section of the mux-controller schema.

dt-bindings: Remove extra blank lines

2025-11-17T17:24:50Z

Generally at most 1 blank line is the standard style for DT schema files. Remove the few cases with more than 1 so that the yamllint check for this can be enabled.

dt-bindings: mux: add optional regulator binding to gpio mux

2025-05-08T12:53:11Z

On some platforms to minimise pop and click during switching between CTIA and OMTP headset an additional HiFi Mux Switch is used. Most common case is that this switch is switched on by default, but on some platforms this needs a regulator enable. One such platform is Lenovo T14s. Adds required bindings in gpio-mux to add such optional regulator.

dt-bindings: Fix properties without any type

2022-05-23T16:53:30Z

Now that the schema tools can extract type information for all properties (in order to decode dtb files), finding properties missing any type definition is fairly trivial though not yet automated. Fix the various property schemas which are missing a type. Most of these tend to be device specific properties which don't have a vendor prefix. A vendor prefix is how we normally ensure a type is defined.

dt-bindings: Drop undocumented i.MX iomuxc-gpr bindings in examples

2022-04-26T18:23:25Z

The i.MX iomuxc-gpr bindings are undocumented and a mess. Drop their use from the examples. The problem with the binding beyond the just random variations is that the iomuxc-gpr is not a separate block, but registers within the iomuxc block containing random leftover controls. As a separate DT node, it creates nodes with overlapping memory addresses.
