Due to dpdm regulator is not being used on newer platform as
ADSP firmware takes care of charger detection, there is no
way to detect USB cable disconnect vs USB spoof disconnect
when EUD is enabled. This change identifies USB spoof
disconnect and provides spoof disconnect related information
to USB PHY driver to avoid turning off PHY clocks and regulators.

The haven RM driver header file exposes functions where notifier
blocks are used. However, not all clients who include the
header file will necessarily have the notifier header file
in their source file, which causes compilation errors. Thus,
include the notifier header file in the RM driver header file
so that all other clients don't have to.

Remove the use of DMA_ATTR_FORCE_NON_COHERENT and
DMA_ATTR_FORCE_COHERENT attributes while allocating and mapping
memory in the fastrpc driver, as they are not supported in a GKI
kernel. Ignore any per-buffer coherency attributes passed by
userspace.
Add a new config option that can be used by the fastrpc driver to
detect if it is being compiled in a QGKI kernel. Read the DMA
coherency property of the fastrpc device nodes only if this config
has been enabled. On a GKI kernel, the cache maintenance will
always be done by the fastrpc driver.

atos_write() uses the IOVA stored in the debug device structure
for translating the input IOVA to a physical address, which is
not correct, given that the debug device structure's IOVA field
has not been initialized yet. Use the IOVA given as an input
for translating the IOVA to a physical address.

Neuron is a device-sharing framework which is used by guests of the
haven hypervisor to serve or access shared I/O devices and other
inter-VM services.
There are three main layers that make up a neuron service.
channel - the physical layer transport that uses the hypervisor
provided transports.
protocol - defines the syntax and semantics to virtualize a specific
device across VMs. Block and Net are examples of protocols.
application - integrates the neuron service components into the rest of
the system. There would be front and back end application
drivers for the net protocol.

extcon_get_edev_name() function provides client driver to request
extcon dev's name. If extcon driver and client driver are compiled
as loadable modules, extcon_get_edev_name() function symbol is not
visible to client driver. Hence mark extcon_find_edev_name() function
as exported symbol.

kernel boot till USB phy driver is initialized based on cable status,
keep regulators on from USB high speed phy driver's probe. Regulators
shall get turn off while handling USB cable disconnect routine for
both boot up with and without USB cable case.

Currently, the cap-id for Tx and Rx of the message-queue are
initialized with 0. However, 0 is a valid value for cap-id.
A better value to initialize the cap-id is with U64_MAX. Hence,
make corrections to use U64_MAX, defined as HH_CAPID_INVAL, in
the message-queue driver.
