[PATCH 2/5] ARM: dts: imx7d-sdb: Assign corresponding power supply for LDOs
From: Anson Huang
Date: Tue May 07 2019 - 02:35:20 EST
On i.MX7D SDB board, sw2 supplies 1p0d/1p2 LDO, this patch assigns
corresponding power supply for 1p0d/1p2 LDO to avoid confusion by
below log:
vdd1p0d: supplied by regulator-dummy
vdd1p2: supplied by regulator-dummy
With this patch, the power supply is more accurate:
vdd1p0d: supplied by SW2
vdd1p2: supplied by SW2
