[PATCH v1 4/9] ARM: dts: imx8mm-verdin: follow changed pmic

Wed Oct 28 10:58:11 CET 2020


From: Max Krummenacher <max.krummenacher at toradex.com>

The used PMIC has been changed from RHOM BD71837 to NXP PCA9450A.
Adjust the device tree accordingly.
Remove the old ADC node as the ADC has been changed and has no longer
a separate power rail.
