The die and connector health properties expose the comparator output of
the thermal regulation. If both die and skin temperature regulation is
enabled then the output of the comparator will be the higher of the two.
The property values can be one of: Unknown, Cool, Warm, Hot, Overheat.

Add support to vote for ICL based on charger type.
Following are the current limit for chargers:
Legacy adapters:
CDP: 1500mA, DCP: 1800mA, HVDCP: 3000mA
TypeC Adapters:
Based on the current advertised by the adapter.

Add support for USBIN-USBIN configuration based parallel charging. This
involves splitting Input Current Limit(ICL) between the main and the
parallel charger, ICL re-split is done when the settled AICL of the main
charger changes by 300mA.

Re-organize SMB1351 charger driver to support new parallel charger
architecture.
- New property "POWER_SUPPLY_PROP_PARALLEL_MODE" exposes the parallel
charger configuration, in this case it is USBIN-USBIN configuration.
- Property "POWER_SUPPLY_CHARGE_TYPE" is added to report the current
charge type and is also used for parallel charger chip detection.

Add support to detect presence of parallel charger chip by
requesting a register read via power_supply framework.
If parallel chip is absent then disable parallel charger.

Add support to delay parallel enable until HVDCP detection
and authentication completes. This involves adding a new voter
which enables parallel charger under following condition:
For DCP: enable parallel path after HVDCP detection
times out.
For HVDCP: enable parallel path after HVDCP authentication
completes.

Currently we have only one path - the pd active setting path - where
ICL_OVERRIDE gets set.
With the upcoming changes to manage connector temperature
mitigation and usbin-usbin parallel charger, the ICL_OVERRIDE is needed
to be set from these usecases.
So instead of creating a voter for ICL_OVERRIDE and putting the onus
on callsites to set it before calling their icl settings, it is best
to handle it in icl_callback.
Update the icl_callback to manage override and suspend in this way.
- Presence of voter signifies that the driver wants to enforce a
value different than the hw default. Force an icl override.
- No voters signifies that the hw defaults are good, undo an override.
- For USB types that command a limit aka SDP and CDP, never override.
- never suspend if there are no clients.

Cleanup the code such that when PD is activated, DCP_VOTER
and USB_PSY_VOTER (the voter for SDP and CDP types) are disabled.
While at it DCP_VOTER is intended to enforce a different value
from the hw defaults. Set it only when type is confirmed DCP.
Also to handle the situation when the PD profile allows to suspend
based on the phy, use a different voter PD_SUSPEND_SUPPORTED_VOTER
to activate that situation.
