gpio_defaults needs to be specified as an unsigned int rather than an
int, because the intention of the DT binding is that all out of range
values for a 16-bit register will cause the defaults to be used,
however, if gpio_defaults is an int then values that are larger than
INT_MAX will become negative numbers and be written out directly to the
hardware. As no where in the code replies on gpio_defaults being an int,
the simplest fix is to just change it to unsigned.

Since commit 6e3f62f079 ("mfd: core: Fix platform-device id
generation") we honour PLATFORM_DEVID_AUTO and PLATFORM_DEVID_NONE when
registering mfd-devices.
Unfortunately, some mfd-drivers rely on the old behaviour of generating
platform-device ids by adding the cell id also to the special value of
PLATFORM_DEVID_NONE. The resulting platform ids are not only used to
generate device-unique names, but are also used instead of the cell id
to identify cells when probing subdevices.
These drivers should be updated to use PLATFORM_DEVID_AUTO, which would
also allow more than one device to be registered without resorting to
hacks (see for example wm831x), but lets fix the regression first by
partially reverting the above mentioned commit with respect to
PLATFORM_DEVID_NONE.

under 85% the target voltage, the buck output will reset. But if the
