When the secure camera starts, we detach the secure CB. We don't
reset the iommu_attached flag to avoid iommu attach during the
secure session. The improper flag value is causing imbalance in
the clock voting, and is causing crashes when secure camera use
cases are run back to back with device suspend/resume.
The sde_smmu_attach function already takes care of avoiding attach
during secure session. So, we can reset the flag to avoid imbalance
in the clock voting.

Based on the hardware recommendation, update the default empty
voltage from 2.8 V to 2.85 V. This is to prevent undervolting
in low temperatures (e.g. -20 C) when battery voltage drops below
2.8 V but the battery SOC may not reach 0% as the charger is
configured to issue GP_FAULT2 when battery voltage goes below
2.8 V. This helps in shutting down graciously.

The added HDMI CEC framework provides a generic kernel interface for
HDMI CEC devices.
Note that the CEC framework is added to staging/media and that the
cec.h and cec-funcs.h headers are not exported yet. While the kABI
is mature, I would prefer to allow the uABI some more time before
it is mainlined in case it needs more tweaks.
This adds the cec-adap.c source that deals with the low-level CEC
messaging and logical address handling.

Currently main charger ends up voting to disable parallel(USBIN_I_VOTER)
if the settled current is less than 1.4Amps. It could be that the
parallel path is drawing some current and the draw is higher than
1.4Amps.
Move this disabling to battery, where the parallel charger's input current
is taken in to consideration.
Also while voting to disable, make sure that the main's input is limited.
If there is more room for ICL to increase that means more power could be
drawn from the charger and so we must keep the parallel charging enabled.
If the ICL ceiling itself if 1.4Amps then disable parallel charging,
because even if ICL has room to increase it wont cross 1.4Amps.
The main's input limited state is set while AICL steps up - this
ensures that we keep parallel disabled while AICL is running and settled
is less than 1.4Amps.
When the charger is removed, the main's input limited status is unset,
however we want to keep the parallel charger disabled. In such situations
the main's settled current is 0mA - use this to vote for disabling
parallel charging.
For any ICL change vote request:
Disable parallel using USBIN_I_VOTER if requested current is less than
1.4Amps and to un-vote (i.e. when ICL vote is higher than 1.4Amps) rely
on event from AICL done or status_change delayed work.
Note that USBIN_I_VOTER is effective only for non-QC chargers. For QC
chargers USBIN_V_VOTER continues to keep charging enabled since parallel
need not be disabled is a lower current is requested with a QC charger.

We clean up the logical end points only for the un-registering device
in bridge mode. However, the other physical end point's local end
point still points to the the un-registered device.
This may lead up to a crash if one of the physical devices in bridge
mode is un-registered. Fix this by unsetting the local endpoint.
It is still possible that packets in a different context across cores
might try to access this data. This usually manifests as packets
requesting a very large headroom. Handle this by dropping these stale
