Proprietary chargers pull D+/- to specific voltages between 2.0-3.3V
(VLGC) for identification. The DM voltage may not exceed VLGC due
to pull-down resistor. Hence a proprietary charger is detected as
a Standard downstream port (SDP). Read line state to distinguish
between SDP and proprietary charger. The DP voltage would exceed
VLGC for proprietary chargers.
D- can be greater than VLGC when a low speed device is attached via
Accessory charger adapter (ACA-A). Hence mark the charger as ACA-A
if ID resistance is RID_A and D- > VLGC

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.

qpnp-gpio manages gpio_chip queries based on the slave
ID. This has a limitation in that it restricts the number of
gpio_chips per slave ID to one. However, some PMICs have both MPP
and GPIO on the same slave, and thus the slave ID is not a
meaningful unit to search for.
Instead, make use of the 'label' binding to give the
primary dev-container node a name. This name will serve as the
gpio_chip label, which can be used in lookups.

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.

Merge commit 'AU_LINUX_ANDROID_ICS.04.00.04.00.126' into
msm-3.4
Since this version is inconsistent with the upstream,
port the irq_domain framework to the version in v3.4 and
makes all necessary changes to clients that are out of spec.
Details of client ports are below.
-Update the qpnp-int driver for revmap irq_domain API. The revmap
irq_domain implementation introduces a reverse lookup scheme using
a radix tree. This scheme is useful for controllers like qpnp-int
that require a large range of hwirqs.
-Bring the ARM GIC driver up to v3.4, being careful
to port existing CAF changes.
-Partially port the gpio-msm-common driver to the new irq_domain API.
Enable the gpio-msm-common driver to work with the new irq_domain
API using a linear revmap. It is not a full port since irq_domain
is still only registered for Device Tree configurations. It should
be registered even for legacy configurations.
In addition, the irq_domains .map function should be setting all
the fields currently done in msm_gpio_probe(). That's not
currently possible since msm_gpio_probe is invoked
unconditionally - even from Device Tree configurations.
Finally, gpio-msm-common should be converted into a real
platform_device so that probe() is invoked due to driver and
device matching.

There could be race condition between h/w initiating sof
(start of frames) and finishing port reset. This can
cause hsic phy lockup, which results in enumeration failure.
Avoid this race condition by:
1. Moving to the old enumeration sequence where set_address is
initiated before get_device descriptor. This results in one
port reset instead of two port resets.
2. Halt usb controller before initiating port reset and start it after
port reset is complete. This is tricky because PORT_RESET bit
automatically clears when h/w completes the reset and failure to
start the controller within 3ms causes the peripheral device to
suspend resulting in enumeration failure. Hence, after setting
port reset bit forcefully drive strobe/data lines to reset using
ulpi interface and once port reset is complete, disable forceful
reset and start the controller in atomic context.
