Subject: [PATCH v4 0/4] Add support for CS40L50

From: James Ogletree <james.ogletree@...rus.com>

This patch series adds support for Cirrus Logic CS40L50, a haptic driver.

While I2S streaming to the device will need to be supported in the future,
no codec driver is included in this submission and therefore this MFD
driver has just one component. A bare bones codec driver can be created
and included if maintainers prefer.

Changes in v4:
- Move from Input to MFD
- Move common Cirrus haptic functions to a library
- Incorporate runtime PM framework
- Coding style related improvements

Changes in v3:
- YAML formatting corrections
- Fix typo in MAINTAINERS
- Use generic node name "haptic-driver"
- Fix probe error code paths
- Use sizeof(*)
- Remove tree reference in MAINTAINERS

Changes in v2:
- Fix checkpatch warnings

James Ogletree (4):
  dt-bindings: input: cirrus,cs40l50: Add initial DT binding
  Input: cs40l50 - Add cirrus haptics base support
  mfd: cs40l50: Add support for CS40L50 core driver
  Input: cs40l50 - Add support for the CS40L50 haptic driver
