Add cs42l43 PC focused SoundWire CODEC

Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:

This patch chain adds support for the Cirrus Logic cs42l43 PC focused
SoundWire CODEC. The chain is currently based of Lee's for-mfd-next
branch.

This series is mostly just a resend keeping pace with the kernel under
it, except for a minor fixup in the ASoC stuff.

Thanks,
Charles

Charles Keepax (4):
  dt-bindings: mfd: cirrus,cs42l43: Add initial DT binding
  mfd: cs42l43: Add support for cs42l43 core driver
  pinctrl: cs42l43: Add support for the cs42l43
  ASoC: cs42l43: Add support for the cs42l43

Lucas Tanure (2):
  soundwire: bus: Allow SoundWire peripherals to register IRQ handlers
  spi: cs42l43: Add SPI controller support
