From bd2259e3c40c097c47e1dfc58a03b1df66b44840 Mon Sep 17 00:00:00 2001 From: Felix Brack Date: Fri, 22 Sep 2017 14:27:28 +0200 Subject: [PATCH] doc: Fix statements on case sensitivity for regulator prefix The regulator bindings state that regulator prefixes are allowd to be in upper or lower case. However pmic_bind_children from pmic_uclass uses strncmp to compare DT node name against prefix. This comparison is case sensitive hence the regulator driver prefix case matters.
