With shared data channel architecture, SLIMBUS driver
only removes slimbus channel when all clients vote to
have channel removed. In case of subsystem restart,
client such as MDM can go down without withdrawing
vote. During CODEC path shutdown, CODEC driver will
receive slimbus slave interrupt in time indicating
port disconnection because slimbus channel has not
be been voted off. Then, CODEC driver blindly
shutdown rest of CODEC path. This results in
overflow error on Rx path and underflow error on
Tx path. In case of time out waiting for port disconnect
interrupts to arrive, force ports to disconnect

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.

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.

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.
