Flushing the core is now done with the V4L2_DEC_QCOM_CMD_FLUSH ioctl
rather than V4L2_DEC_CMD_STOP. The latter is confusing and the
arguments specified by the V4L2 spec do not allow for flushing the input
and and output buffers seperately.

The Contiguous Memory Allocator is a set of helper functions for DMA
mapping framework that improves allocations of contiguous memory chunks.
CMA grabs memory on system boot, marks it with MIGRATE_CMA migrate type
and gives back to the system. Kernel is allowed to allocate only movable
pages within CMA's managed memory so that it can be used for example for
page cache when DMA mapping do not use it. On
dma_alloc_from_contiguous() request such pages are migrated out of CMA
area to free required contiguous block and fulfill the request. This
allows to allocate large contiguous chunks of memory at any time
assuming that there is enough free memory available in the system.
This code is heavily based on earlier works by Michal Nazarewicz.

Currently the code does not have a mechanism to remember the soc
reported just before shutting down and upon restarting the new
soc reported is off from the previous soc value reported.
This change introduces
- a method to save soc in an unused coincell back register: ssbi address
0x107 is not used on 8921 and serves the purpose of storing the soc.
The driver reads this value and uses it to scale the reported soc.
- a method to detect that a battery was removed and perhaps replaced by a
different one. If the battery is found replaced the driver is notified
of the change and it disregards the soc value it read from the backup
register. The charger driver has a battery backed bit (force vref
therm) which it sets in its initialization sequence. Once set the
value remains between restarts, unless the battery is removed. The
default value of this bit is 0. Hence if a zero is detected before
writing to it, battery was removed between restarts - this mechanism
is used to notify the BMS to disregard the soc read from the backup
register.
Note that for this to work correctly the bootloader needs to be updated to
not overwrite register 0x107 upon restart.

The MIGRATE_CMA migration type has two main characteristics:
(i) only movable pages can be allocated from MIGRATE_CMA
pageblocks and (ii) page allocator will never change migration
type of MIGRATE_CMA pageblocks.
This guarantees (to some degree) that page in a MIGRATE_CMA page
block can always be migrated somewhere else (unless there's no
memory left in the system).
It is designed to be used for allocating big chunks (eg. 10MiB)
of physically contiguous memory. Once driver requests
contiguous memory, pages from MIGRATE_CMA pageblocks may be
migrated away to create a contiguous block.
To minimise number of migrations, MIGRATE_CMA migration type
is the last type tried when page allocator falls back to other
migration types when requested.

Add mpp support to the qpnp-pin driver. MPP support allows for
additional devices to be specified in the Device Tree topology.
This support is implemented in the same driver as the GPIO
support since the address map is very close between them.
The addition of this support does not change the existing gpio
support.
Default MPP configuration can be specified in the Device Tree
using the three new bindings for mpp. Any attribute not specified
in the Device Tree will assume its default configuration.
It's also possible to configure an MPP at runtime using the
existing qpnp_pin_config() API. If a given configuration feature
is not supported by the underlying hardware pin, then that
particular request is silently dropped with no error. This allows
for gpio users to continue specifying only a subset of the full
qpnp_pin_cfg structure.

meaningful unit to search for.
Instead, make use of the 'label' binding to give the

Since we support multiple device_nodes per spmi_device when used
with the spmi-dev-container flag, it's often unclear how a driver
should make reference to a particular device. Therefore,
introduce the spmi specific binding spmi-dev-name that specifies
the device name for the device_node.
Also introduce an API that can be used from
the driver to lookup the specific device node associated with a
particular device name.
Note that it may seem at first glance that the binding 'label' is
redundant with device_node->name. However, per the ePAPR,
device_node->name is intended to be as generic as possible,
representing the function of the device and not the precise
programming model. 'label' is used to give a platform
specific name that can be queried from device drivers.

reg-names and interrupt-names are standard bindings to map device
tree reg and interrupt indices to particular names. This way the
driver does not need to be concerned with hard coded assignments.
Therefore, add spmi support for these bindings.
Explicit support for reg-names is required since the
implementation does not make use of of_address_to_resource(),
which happens to already support this.
This is because of_address_to_resource() mandates address
translation, which is not relevant to spmi.
interrupt-names is already implicitly handled by
of_irq_to_resource(), which is used in the spmi implementation.
Add additional documentation to state clearly that this binding
is also supported.
Also add supporting routines to easily lookup a resource by name
for both registers and interrupts.

Pointers are more flexible than index numbers, since index
numbers depend upon an additional reference to the array in
question. In particular, we'd like to add a new API to lookup a
devnode based on a predefined name in the Device Tree. This API
will return a spmi_resource, and so it's natural to want to use
this pointer directly with the other existing APIs.
Also introduce a new API spmi_for_each_devnode that can be used
to iterate each spmi_resource in the dev_node array. This
abstracts the traversal of the array, which was previously done
within the existing APIs.
