soundwire: fix regmap dependencies and align with other serial links

2019-10-07T16:57:27+00:00

[ Upstream commit 8676b3ca4673517650fd509d7fa586aff87b3c28 ]

The existing code has a mixed select/depend usage which makes no sense.

config SOUNDWIRE_BUS
       tristate
       select REGMAP_SOUNDWIRE

config REGMAP_SOUNDWIRE
        tristate
        depends on SOUNDWIRE_BUS

Let's remove one layer of Kconfig definitions and align with the
solutions used by all other serial links.

soundwire: intel: fix channel number reported by hardware

2019-10-07T16:57:11+00:00

[ Upstream commit 18046335643de6d21327f5ae034c8fb8463f6715 ]

On all released Intel controllers (CNL/CML/ICL), PDI2 reports an
invalid count, force the correct hardware-supported value

This may have to be revisited with platform-specific values if the
hardware changes, but for now this is good enough.

soundwire: stream: fix out of boundary access on port properties

[ Upstream commit 03ecad90d3798be11b033248bbd4bbff4425a1c7 ]

Assigning local iterator to array element and using it again for
indexing would cross the array boundary.
Fix this by directly referring array element without using the local
variable.

soundwire: Fix acquiring bus lock twice during master release

2018-08-27T04:19:48+00:00

As part of sdw_stream_remove_master(), sdw_stream_remove_slave() is called
which results in bus lock being acquired twice.

So, fix it by performing specific Slave remove operations in
sdw_release_master_stream() instead of calling sdw_stream_remove_slave().

soundwire: Fix incorrect exit after configuring stream

2018-08-27T04:19:48+00:00

In sdw_stream_add_master() after the Master ports are configured,
the stream is released incorrectly.

So, fix it by avoiding stream release after configuring the Master
for the stream.
While at it, rename the label appropriately.

soundwire: Fix duplicate stream state assignment

2018-08-27T04:19:48+00:00

For a SoundWire stream it is expected that a Slave is added to the
stream before Master is added.

So, move the stream state to CONFIGURED after the first Slave is
added and remove the stream state assignment for Master add.
Along with these changes, add additional comments to explain the same.
