Hi Paul,

I've finally found one of em-x270 to test on...

If you make this:
REGULATOR_CONSUMER(ldo3, NULL, "vcc gps");

and this:
REGULATOR_CONSUMER(ldo19, NULL, "vcc gprs");

the device even boots...

Thanks for the patch, with the changes above:
Tested-by: Igor Grinberg <grinberg at compulab.co.il>

Haojian, can this patch be included in your pull request (or another one)?
It fixes the build for em_x270_defconfig and with the updates above
gets the board to boot.

Thanks.
