"force_mode" is a u32 so it is never "< 0", but because of type
promotion then comparing "== -1" will do what we want.

This adds the missing state parameter to the call down to the RPM. This
is currently hard coded to the active state, as that's all we're
supporting at this moment.

The of_get_regulator_init_data() function is used to extract the regulator
init_data but information on how to extract certain data is defined in the
static regulator descriptor (e.g: how to map the hardware operating modes).

Add a const struct regulator_desc * parameter to the function signature so
the parsing logic could use the information in the struct regulator_desc.

of_get_regulator_init_data() relies on of_get_regulation_constraints() to
actually extract the init_data so it has to pass the struct regulator_desc
but that is modified on a later patch.

The IPQ8064 reference boards make use of SMB208 regulators which are
controlled by RPM.  Implement support for these regulators in the RPM

A platform_driver does not need to set an owner, it will be populated by the

Current code does not take the macro parameter, fix it.
This is not a problem at this moment because the only user actually passes
vreg to FORCE_MODE_IS_2_BITS().

Doing so generates a warning as the first field is a pointer but we use
0 to initialize it.
