soundwire: fix regmap dependencies and align with other serial links

2019-08-09T04:50:40+00:00

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: cadence_master: fix definitions for INTSTAT0/1

2019-08-02T12:22:16+00:00

Two off-by-one errors: INTSTAT0 missed BIT(31) and INTSTAT1 is only
defined on first 16 bits.

Looks like there is a copy paste error.
This patch fixes it!

soundwire: stream: fix bad unlock balance

2019-06-06T17:16:04+00:00

the msg lock is taken for multi-link cases only but released
unconditionally, leading to an unlock balance warning for single-link usages
This patch fixes this.

 =====================================
 WARNING: bad unlock balance detected!
 5.1.0-16506-gc1c383a6f0a2-dirty #1523 Tainted: G        W

 aplay/2954 is trying to release lock (&bus->msg_lock) at:
 do_bank_switch+0x21c/0x480
 but there are no more locks to release!

soundwire: intel_init: add checks on link numbers

2019-05-27T05:23:00+00:00

Add mask to correctly read the SoundWire SHIM LCAP register. Only bits
2..0 are meaningful, the rest is about link synchronization and stream
channel mapping. Without this mask, the hardware information would
always be larger than whatever the BIOS would report.

Also trap the case with zero links.

This information will be reflected in debugfs but it's easier to see
as a dmesg log.
