The WCD9320 Codec Driver is an ALSA-compliant codec driver. This driver
constructs the internal codec audio paths with DAPM widgets and
controls and provides the controls to the upper layers to enable and
configure audio paths.

The current core assumes TABLA as the only codec driver registering.
To support single binary for multiple targets its essential that
we remove this restriction and move to a generic framework
to support multiple codec. This can be done by moving all codec
specific code to dedicated codec driver and use core driver to probe
the codec based on slimbus device id and do generic setup for the
codec. This also helps to have same boards with different flavours
of codec variants.
The WCD9XXX family of codecs share the initial codec register
mapping which holds the Slimbus device id to identify the
codec existing on the target.Core driver now registers the
codec device based on this check.

Add a driver to control the battery alarm module of PMIC PM8xxx
devices. This module uses a pair of comparators to determine
when battery under and over-voltage take place. A wakeup
interrupt is triggered in these cases which can then run any
notifiers which have been registered. Also add APIs to
configure the threshold voltages and the frequency at which the
hardware checks the state of the battery voltage.

1. Gain
2. Mute/Unmute

The above operations are supported by driver by exported apis
from kernel space.The Machine driver from ALSA would use these

Qualcomm PM8xxx chips, such as PM8058 and PM8921, have 8 channels of
PWM, also called LPG (Light Pulse Generator) in HW specs. All PWM
channels can be used as simple PWM machine or as a more advanced PWM
pattern generator using programmed lookup table.
This patch supports all APIs listed in <linux/pwm.h> with a small
difference. The two parameters (duty_ns and period_ns) in pwm_config()
are used as values in microseconds instead of nanoseconds. Otherwise a
32-bit integer can't fit for a range of 7 us to 300+ seconds.

Add support for the irq controller in Qualcomm PM8821 pmic. The
interrupt controller provides control for MPPs configured as
interrupts in addition to other subdevice interrupts.
The PM8821 IRQ controller is simpler than Secure IRQ controller
in other PMIC4 family of chips, i.e. PM8921. Also, it does not adhere
to SSBI register layout of Secure IRQ controller. This driver follows
the SSBI register layout of PM8821 IRQ controller and supports only
PM8821 IRQ controller.
The interrupt controller also provides a way to read the real time
status of an interrupt. This real time status is the only way one
can get the input values of gpio and mpp lines.

The bms driver calibrates the ccadc channel every few minutes
for offset and gain.
The offset value calibrated needs to be written to the bms hardware
which it uses to adjust all the ccadc readings.
The software has to only adjust for gain for ccadc based readings.
One is not supposed to program the trim offset values in while a
bms conversion in progress. Update the code to try only two times
instead of 10 to check if the conversion is finished, if not enable
the ccadc eoc interrupt and write the values then.

LDO - low drop out regulator (supports both NMOS and PMOS LDOs)
NLDO1200 - 1.2A NMOS LDO (different control structure than other LDOs)
SMPS - switched-mode power supply
FTSMPS - fast transient SMPS
VS - voltage switch
VS300 - 300mA voltage switch (different control structure than
other switches)
NCP - negative charge pump
The driver interfaces with the PMIC using Qualcomm's SSBI bus.
Calls to this bus are abtracted through the pm8xxx_readb/writeb API.

If the PHYs are reset at during usbhs core driver, host ports will
not work because EHCI driver is loaded after the resetting PHYs.
