Subject: [PATCH 5.15 05/35] ARM: dts: at91: fix low limit for CPU regulator

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

[ Upstream commit 279d626d737486363233b9b99c30b5696c389b41 ]

Fix low limit for CPU regulator. Otherwise setting voltages lower than
1.125V will not be allowed (CPUFreq will not be allowed to set proper
voltages on proper frequencies).
