[PATCH 3/5] ARM: dts: imx6sl-evk: Assign corresponding power supply for LDOs
From: Anson Huang
Date: Tue May 07 2019 - 02:35:23 EST
On i.MX6SL EVK board, sw2 supplies vdd1p1/vdd2p5/vdd3p0 LDO, this
patch assigns corresponding power supply for vdd1p1/vdd2p5/vdd3p0
to avoid confusion by below log:
vdd1p1: supplied by regulator-dummy
vdd3p0: supplied by regulator-dummy
vdd2p5: supplied by regulator-dummy
With this patch, the power supply is more accurate:
vdd1p1: supplied by SW2
vdd3p0: supplied by SW2
vdd2p5: supplied by SW2
Signed-off-by: Anson Huang <Anson.Huang@xxxxxxx>
