Question regarding eMMC on iMX6...

I'm on new hardware trying to connect the kernel to eMMC.  At u-boot I am able to work with

the device without a problem so I know the hardware is good.  When I boot the kernel, I get

the following errors at startup:

sdhci: Secure Digital Host Controller Interface driver

sdhci: Copyright(c) Pierre Ossman

sdhci-pltfm: SDHCI platform and OF driver helper

mmc0: no vqmmc regulator found

mmc0: no vmmc regulator found

mmc0: SDHCI controller on 2194000.usdhc [2194000.usdhc] using ADMA

mmc1: no vqmmc regulator found

mmc1: no vmmc regulator found

mmc1: SDHCI controller on 2198000.usdhc [2198000.usdhc] using ADMA

mmc2: no vqmmc regulator found

mmc2: no vmmc regulator found

mmc2: SDHCI controller on 219c000.usdhc [219c000.usdhc] using ADMA


Is this a warning I can ignore (since the device is working with u-boot)?  Or is there something I

need to deal with here?  The code in drivers/mmc/host/sdhci.c where this originates prints this

with "pr_info" and just continues, so I'm assuming that it should still work right?

I should see something in /proc/partitions if this is working right?
