Subject: [PATCH 5/9] ARM: dts: at91: sama5d2_icp: specify proper regulator output ranges
Date: Fri, 26 Aug 2022 11:39:23 +0300	[thread overview]
Message-ID: <20220826083927.3107272-6-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <20220826083927.3107272-1-claudiu.beznea@microchip.com>

Min and max output ranges of regulators need to satisfy board
requirements not PMIC requirements. Thus adjust device tree to
cope with this.

Fixes: 68a95ef72cef ("ARM: dts: at91: sama5d2-icp: add SAMA5D2-ICP")
