[PATCH v2 07/10] ARM: dts: at91: sama7g5ek: set regulator voltages for standby state

From: Claudiu Beznea
Date: Thu Jan 13 2022 - 09:48:25 EST


Set regulator voltages for standby state to avoid wrong behavior of
system while in standby. The CPU voltage has been chosen as being the
one corresponding to OPP=600MHz. Next commit will set the 600MHz OPP
as the suspend OPP.
