From d44870ff2ad5123c74b81ac198c793a2caf84c35 Mon Sep 17 00:00:00 2001 From: Sven Peter Date: Sat, 12 Jul 2025 19:18:58 +0100 Subject: [PATCH] dt-bindings: nvmem: fixed-layout: Allow optional bit positions 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.
