During slow insertion of headset, it may be possible that the

Fix by polling the microphone voltage after a plug is detected

a valid headset voltage, correct the plug type from Headphone to

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.

Switch control of most PMIC PM8941 and PM8841 regulators from
direct native control via qpnp-regulator to indirect RPM control
via rpm-regulator-smd for MSM8974.
Also select MSM_RPM_REGULATOR_SMD for MSM8974 in the MSM8974
Kconfig file. This is necessary because acpuclock-krait requires
that either CONFIG_MSM_RPM_REGULATOR_SMD not be defined or that
it be defined and that the rpm-regulator-smd devices are
available. This requires that the switch from qpnp-regulator to
rpm-regulator-smd devices happen at the same time as
CONFIG_MSM_RPM_REGULATOR_SMD is defined.
Add more supply bindings in msm8974.dtsi so that the
acpuclock-krait driver may be able to successfully call
rpm_regulator_get().
Specify a qcom,consumer-supplies binding in the pm8841_s2_corner
device node for clock-8974.
Modify the voltage ranges for PM8841 SMPS 1 and SMPS 2. The
ranges when using qpnp-regulator control were:
S1 - 900000 to 1150000 uV
S2 - 900000 to 1150000 uV
Change these ranges to:
S1 - 675000 to 1050000 uV
S2 - 500000 to 1050000 uV
When using RPM control, it is safe to allow requests all the way
down to retention voltage levels. The max_uV change is a
correction. 1.15 V is not a supported voltage for S1 or S2.

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.

cdiv clocks treat the zero rate as a special rate indicating 'use
the external source'. The initial rate of a clock's rate field is
typically zero. Combine the two facts with the addition of code
to check if the rate has changed between the last clk_set_rate()
call and you find that clk_set_rate(cdiv, 0) will not do what is
advertised (namely switch to the external source).
To solve this dilemma set the rate of the cdiv clock to ULONG_MAX so
that the check for the same rate doesn't trigger.

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.
