From bc046b952a5494b0dc53be28779460cee1214a3f Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Thu, 24 Feb 2022 11:30:30 +0100 Subject: [PATCH] arm64: dts: imx8mn-evk: fix the min/max voltages of the PMIC Use the proper voltages as supported by the board instead of the ones supported by the PMIC. The voltages were taken from both the schematic of the 8MNANOLPD4-EVK eval board and the datasheet of the IMX8MN SoC.
