[PATCH v3 1/2] dt-bindings: regulator: pca9540: add debounce timer configuration
From: Martijn de Gouw
Date: Mon Nov 17 2025 - 15:22:41 EST
Make the different debounce timers configurable from the devicetree.
Depending on the board design, these have to be set different than the
default register values.
