Re: [PATCH v7 1/6] DONOTMERGE: arm64: dts: ti: Add TI TPS65219 PMIC support for AM642 SK board.

[Wadim Egorov <W.Egorov@phytec.de>]

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
