From efe9a6da2292e68d45cd9e0eb1c31b85841d0c2a Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 23 Feb 2024 17:07:51 -0700 Subject: [PATCH] regulator: dt-bindings: gpio-regulator: Fix "gpios-states" and "states" array bounds The minimum number of array entries for "gpios-states" was not not specified, so the the default is the same as the max (8). The minimum is also missing from "states", and the maximum is also wrong as it should be 2^(# of GPIO lines). Since there can be 1 to 8 GPIOs, the "states" range should be 2 to 256.
