Subject: [PATCH 03/15] arm64: dts: imx8mp-evk: fix BUCK/LDO voltage
From: Peng Fan <peng.fan@....com>
Per PCA9450C datasheet, the voltage range as below:
BUCK1 0.6 - 2.1875
BUCK2 0.6 - 2.1875
BUCK4 0.6 - 3.4
BUCK5 0.6 - 3.4
BUCK6 0.6 - 3.4
LDO1 1.6-1.9, 3.0-3.3
LDO2 0.8 – 1.15
LDO3 0.8 - 3.3
LDO4 0.8 - 3.3
LDO5 1.8 - 3.3
So correct them, and also add LDO[2,4]
Fixes: 5497bc2a2bff ("arm64: dts: imx8mp-evk: Add PMIC device")
