[PATCH 0/5] soundwire: only clear valid interrupts

[Bard Liao]

We wrote 1 to the handled interrupts bits along with 0 to all other bits
to the SoundWire DPx interrupt register. However, DP0 has reserved fields
and the read-only SDCA_CASCADE bit. DPN also has reserved fields. We should
not try to write values in these fields.
Besides, we deal with pending interrupts in a loop but we didn't reset the
slave_notify status.

Pierre-Louis Bossart (5):
  soundwire: bus: add comments to explain interrupt loop filter
  soundwire: bus: reset slave_notify status at each loop
  soundwire: registers: add definitions for clearable interrupt fields
  soundwire: bus: only clear valid DP0 interrupts
  soundwire: bus: only clear valid DPN interrupts
