PMIC 1.0 hardwares need trimming of 2.2k internal resisitor.
From 2.0 HW trimming is expected to be done at Factory.
So perform trim only for 1.0 HW.

The stark based wireless charger need not delay drawing current from
DC path. The wireless insertion work was created just to provide the
delay after the pad was detected to be present.
Remove this code.

MSM8939 has CPR for controlling voltage on VDD_APC.
Also, VDD_APC is supplied from external buck regulator.
Update voltage step_size and CPR step_quotient values
according to external buck regulator in use.

On some platforms the SSPHY and HSPHY are actually shared
multi-port PHYs that are paired with separate DWC3 controllers.
In this case suspending into low power mode must not be allowed
unless all instances are suspended. Add reference counting to
keep track of when all ports have suspended before allowing PHY
to be placed in low power mode.
The approaches used for the SS versus the HS PHY are slightly
different, so the reference counting semantics differ as follows:
- The HS PHY instances can be operated more or less indepedently,
as each port has its own set of QSCRATCH registers. The only
exception is the PHY reset, which is managed by the primary
instance. So the reference counter is added as a static global
to keep track across multiple instances of when to allow reset.
- The SS PHY instances can share a single device driver instance,
as only the primary controller QSCRATCH registers are useful.
Both controllers can then share the same PHY device, so reference
counting is added within the instance structure and is used to
prevent powering off the PHY until all instances have called
set_suspend(0).

Add code to periodically update the readings of the following
power supply properties:
* POWER_SUPPLY_PROP_VOLTAGE_NOW
* POWER_SUPPLY_PROP_VOLTAGE_OCV
* POWER_SUPPLY_PROP_TEMP
* POWER_SUPPLY_PROP_CURRENT_NOW
The properties are updated in 30 second increments, unless
a fg_power_get_property happens prior, then a pending work
queue is canceled and the work is scheduled within 1 second
of the request.
Note that if a client abuses the userspace the work sync
will not be able to be rescheduled and thus may lead
to stale cached values.
