[PATCH] qi: initialize PMU GPIOs

[Werner Almesberger]

Joerg,

thanks for reporting this critter. Can you please test the patch
below ?

- Werner

------------------------------- cut here --------------------------------

The PMU initializes all GPIOs to inputs in NoPower, including GPIO2,
which drives GSM_ON and has an external pull-up. Furthermore, we may
have entered PMU.Standby with the modem up.

Unlike u-boot, qi didn't initialize the GPIOs. With this patch is
does.
