[PATCH 0/4] ASoC: cs35l56: Switch to using the IRQ from the SoundWire core

At the time the cs35l56 driver was written the only way to get interrupts
from the SoundWire core was to implement a custom handler inside the
interrupt_callback() function.

The SoundWire core now provides a virtual IRQ for notifying ImpDef
interrupts, and switching to this simplifies the code and also makes it
more similar to the normal interrupt handling of I2C/SPI (though some
SoundWire specials are still needed).

Patches #1 and #2 do some preparatory code shuffling so that there is
less clutter in patch #4.

Patch #3 changes the SoundWire core code to create the virtual ImpDef IRQ
before calling the codec drive probe() so that the IRQ can be requested in
probe().

Richard Fitzgerald (4):
  ASoC: cs35l56: Request IRQ in cs35l56_common_probe()
  ASoC: cs35l56: Move cs35l56_irq_request() after cs35l56_irq()
  soundwire: bus_type: Create IRQ mapping before calling driver probe()
  ASoC: cs35l56: Use IRQ provided by the SoundWire core
