[PATCH 4/9] ARM: dts: at91: sama5d27_wlsom1: specify proper regulator output ranges
From: Claudiu Beznea
Date: Fri Aug 26 2022 - 04:37:41 EST
Min and max output ranges of regulators need to satisfy board
requirements not PMIC requirements. Thus adjust device tree to
cope with this.
Fixes: 5d4c3cfb63fe ("ARM: dts: at91: sama5d27_wlsom1: add SAMA5D27 wlsom1 and wlsom1-ek")
