Subject: [PATCH v5 0/5] Add support for CS40L50

There is a massive delta from V4, so only the highlgihts are
mentioned below. I intend for this version to address all
feedback to-date, so if you find something left unaddressed
then please let me know.

Changes in v5:
- Added a codec sub-device to support I2S streaming
- Moved write sequencer code from cirrus_haptics to cs_dsp
- Reverted cirrus_haptics library; future Cirrus input
  drivers will export and utilize cs40l50_vibra functions
- Added more comments
- Many small stylistic and logical improvements

Changes in v4:
- Moved from Input to MFD
- Moved common Cirrus haptic functions to a library
- Incorporated runtime PM framework
- Many style improvements

Changes in v3:
- YAML formatting corrections
- Fixed typo in MAINTAINERS
- Used generic node name "haptic-driver"
- Fixed probe error code paths
- Switched to "sizeof(*)"
- Removed tree reference in MAINTAINERS

Changes in v2:
- Fixed checkpatch warnings

James Ogletree (5):
  firmware: cs_dsp: Add write sequencer interface
  dt-bindings: input: cirrus,cs40l50: Add initial DT binding
  mfd: cs40l50: Add support for CS40L50 core driver
  Input: cs40l50 - Add support for the CS40L50 haptic driver
  ASoC: cs40l50: Support I2S streaming to CS40L50
