dt-bindings: nvmem: Add the nxp,s32g-ocotp yaml file

2025-09-12T13:49:03+00:00

Add bindings to expose the On Chip One-Time Programmable Controller (OCOTP) for the NXP s32g chipset. There are three versions of this chip but they're compatible so we can fall back to the nxp,s32g2-ocotp compatible.

dt-bindings: Correct indentation and style in DTS example

2025-07-29T00:56:29+00:00

DTS example in the bindings should be indented with 2- or 4-spaces and aligned with opening '- |', so correct any differences like 3-spaces or mixtures 2- and 4-spaces in one binding. No functional changes here, but saves some comments during reviews of new patches built on existing code.

dt-bindings: nvmem: mediatek: efuse: split MT8186/MT8188 from base version

2025-07-16T12:30:05+00:00

On MT8186 and MT8188 one of the NVMEM cells contains the GPU speed bin value. In combination with the GPU OPP bindings, on these two platforms there is an implied scheme of converting the cell value to what the GPU OPP "opp-supported-hw" property matches. This does not apply to the base mediatek,efuse hardware, nor does it apply to any of the other platforms that do not have the GPU speed bin cell. The platform maintainer argues that this makes the compatibles incompatible with the base "mediatek,efuse" compatible, as shown in the link given. Deprecate the MT8186/MT8188 + "mediatek,efuse" combination, and add new entries with MT8186 being the base model and MT8188 falling back to MT8186.

dt-bindings: nvmem: fixed-layout: Allow optional bit positions

2025-07-16T12:30:04+00:00

NVMEM nodes can optionally include the bits property to specify the bit position of the cell within a byte. Extend patternProperties to allow adding the bit offset to the node address to be able to distinguish nodes with the same address but different bit positions, e.g. trim@54,4 { reg = <0x54 1>; bits = <4 2>; }; trim@54,0 { reg = <0x54 1>; bits = <0 4>; }; Before the conversion to NVMEM layouts in commit bd912c991d2e ("dt-bindings: nvmem: layouts: add fixed-layout") this extension was originally added with commit 4b2545dd19ed ("dt-bindings: nvmem: Extend patternProperties to optionally indicate bit position") to the now deprecated layout.
