Subject: [PATCH 5.15 063/121] ARM: dts: at91: sama5d27_wlsom1: specify proper regulator output ranges

From: Claudiu Beznea <claudiu.beznea@...rochip.com>

[ Upstream commit addf7efec23af2b67547800aa232d551945e7de2 ]

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")
