This is not (quite) working for me on our custom AM335x board.

Everything compiles fine, but I get the following in the boot log:-

[    1.339805] omap_hsmmc 48060000.mmc: vmmc regulator missing

I can see that the regulator *does* get enabled, but later on in the boot process !!

[    1.611901] tps65217 0-0024: TPS65217 ID 0xe version 1.2

I can only think this is the cause of the issue.

However ... cards plugged into the sd card slot are seen and are mount-able.

I've attached my board dts and .config if that helps.

Any clues ?
