Issue - backend dai prepare fails with concurrent LPA and non-LPA
sessions during stability tests. Since front end dai reference
count gets incremented for both sessions and backend dai hw_params
doesnt get invoked. This results NULL pointer in backend dai hw_params.
Fix - use the flag hwparam_set to ensure backend dai hw_parmas is
invoked properly.

When registering irq chip drivers, one common requirement is to
specify the irq_domain irq_base and nr_irq. These fields represent
the system wide logical interrupt range the domain occupies.
For systems with only one interrupt controller, it's trivial to
know these values. But for systems with several irq chip drivers,
it becomes painful to keep track of interrupt ranges in platform
defines. These create needless compile time dependencies, of
which the Device Tree aims to solve.
irq_alloc_desc() can search for a free irq, but is very
inefficient for determining the availability of large ranges.
Additionally, some irq chip drivers allocate irq descriptors
lazily. For example, portions of the Device Tree may not be parsed
until a particular bus is probed. But of_irq_init() is intended to
be run at init time, and this is a natural time to allocate irq
domains. Thus by the time we allocate our irq descriptors, we already
need to know a range of acceptable irqs to use for the domain.
To solve these problems, let's introduce
irq_domain_find_free_range(), which will return to the caller the
first available irq domain range not used already by the system.
This range can then be specified with irq_domain_add().

It should not be valid to add an irq_domain with a logical irq
range that overlaps with another already registered to the
system. Return an error on such an occurrence.
This change also inherently sorts the irq_domains by logical
irq_base as they are added.

The current irq_domain_add() design assumes the underlying
irq_descs are valid when irq_domain_add() is called. It also
assumes that every hwirq enlisted in the irq_domain is valid.
Often, these assumptions are not correct.
Typically, irq_domain_add() is called at board_init time, but
sometimes interrupt chip drivers are not initialized until an
underlying bus is probed. When using SPARSE_IRQ, it's quite
natural to hold off allocating irq_descs until the board
topology specifies them as included.
And in such device topologies, there's no guarantee that chip
interrupt numbers will be contiguous. For example, each hwirq may
map to a particular device, but that device may or may not be
present in the actual hardware configuration. In order to support
this, we need the concept of an irq_domain that supports holes
in it.
In order to solve these problems, let's break the irq_domain
creation from the irq registration process. The irq_domain
creation can occur at init time and then have no dependencies. An
interrupt is not 'registered' with the domain until its resources
have already been allocated by the chip driver. For simple cases,
an additional API is provided to register the entire
logical irq_domain range to provide feature parity with what
already exists.

Allow client to send information to replace a specific field of
the cmd buffer with the physical address. This is done via a new
IOCTL, TZCOM_IOCTL_SEND_CMD_FD_REQ, which is used to import the
ion fd handle. This IOCTL takes in a new send_cmd_fd_op_req
structure that has the same format as send-cmd_op_req with a
new field added: an array of ion handles (ifd_data.fd) and
cmd_buf_offset.
The client sends in an array of ion fd handle along with the
offset to the command buffer field.
This new IOCTL allows a client to send information regarding
which field(s) (at cmd_buf_offset) in the cmd_buf to replace.
These field(s) are replaced with the physical addr of the
buffer addressed by the respective ifd_data.fd handle.

Allow the pm8921-charger driver to initiate charging on a
registered 3rd party charging driver through the power supply class.
Also enable the maintenance of charging properties such as online
and charge type using the power supply class rather than
directly depending on the 3rd party driver.
When a external charger is registered using power_supply_register
the external_power_changed callback of the charger driver checks
for an external charger named "dc". This removes the dependency
of a 3rd party charger to call directly into the charger driver.
Also, update the isl9519q driver to reflect the changes and
utilize power supply class calls to enable charging
on the isl chip from PM8921 charger driver.
This serves as an example for other 3rd party external
chargers supporting PMIC with high current charging.
Finally, add pr_fmt macro which automatically adds function name
to print statements and remove __func__ from individual print
statements.

Add power_supply_set_charge_type to enable a charger driver to set

a request, the receiving charger driver then can handle the request
and report the adequate POWER_SUPPLY_PROP_CHARGE_TYPE once necessary
action has been taken.
