Copy speaker configuration from active to inactive bank
and perform bank switch operation while speaker channels
are getting enabled or disabled. This will make sure that
soundwire banks are always in sync and allow independent
control of speaker channels.

Handle soundwire slave devices ungroup in master controller.
Set the group device id to 0 when soundwire slave devices
request ungroup for independent control.

Soundwire hardware has two banks for configuring soundwire
slave ports. After playback is stopped, disable soundwire slave
ports in both banks to avoid any port collisions during the start
of next playback on other slave device.

Put soundwire in suspend state when system is in idle state.
This will avoid power consumption on speakers when system is in
idle state.

sync to pm runtime increments the count and calls soundwire runtime
resume function. This is not needed for every soundwire register read
and write operation. Change removes syncing to pm runtime during
soundwire register read and write operations.

Before runtime PM is marked as suspended for the device, runtime
PM should be suspended for synchronization purpose. Without this,
the RPM status might not be updated to suspended and system might
go out of sync.

Runtime suspend and resume hooks are already taking care
of disabling and enabling the clocks.So need to do the same
in system suspend and resume. Otherwise it results in
disabling of clock when needed during suspend.

Slave devices attached to the WCD soundwire master would perform
device enumeration to determine the devices connected on the bus.
To perform this enumeration, call soundwire startup function to
invoke slave device startup function.

In soundwire read/write commands, register value is defined
as 8 bit but it is accessed through 32 bit pointer which
may cause out of boundary memory access. Fix this issue by
typecast appropriately.

there is no active stream. This will save power when
there is no audio usecase through soundwire interface.

Add soundwire master driver for soundwire master controller.
This driver initializes soundwire master controller
hardware and adds soundwire slave devices to the bus.
It handles all the interrupts generated by soundwire bus.
It also handles the port configuration of slave devices and
master for audio data transfer between master and slave ports.
