Subject: Re: [PATCH v7 1/6] DONOTMERGE: arm64: dts: ti: Add TI TPS65219 PMIC
support for AM642 SK board.
Hi Jerome,
is this setup working for you on the AM642 SK board?
I am testing your PMIC patches on a AM62 based board with a similar setup and
running into the following error
VDDSHV5_SDIO: bypassed regulator has no supply!
VDDSHV5_SDIO: will resolve supply early: ldo1
VDDSHV5_SDIO: supplied by regulator-dummy
VDDSHV5_SDIO: failed to get the current voltage: -EINVAL
Have you noticed problems with LDO1 and bypass mode?
Regards,
Wadim
