From caafc6c497db9fba3007c537e92cf3b184f8c1e3 Mon Sep 17 00:00:00 2001 From: Max Krummenacher Date: Wed, 28 Oct 2020 11:58:11 +0200 Subject: [PATCH] ARM: dts: imx8mm-verdin: follow changed pmic 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.
