Message

Introduce driver for Cirrus Logic Device CS40L26:
A boosted haptics driver with integrated DSP and
waveform memory with advanced closed loop algorithms
and LRA protection.

The core CS40L26 driver is in MFD and touches the
Input Force Feedback subsystem for haptics and
the ASoC subsystem for audio to haptics streaming.

This patchset includes changes to the CS DSP firmware
driver which fixes two bugs and introduces support for
multiple coefficient files.

Fred Treven (7):
  firmware: cs_dsp: Fix error checking in wseq_write()
  firmware: cs_dsp: Check for valid num_regs in
    cs_dsp_wseq_multi_write()
  firmware: cs_dsp: Add ability to load multiple coefficient files
  dt-bindings: mfd: cirrus,cs40l26: Support for CS40L26
  mfd: cs40l26: Add support for CS40L26 core driver
  ASoC: cs40l26: Support I2S streaming to CS40L26
  Input: cs40l26 - Add support for CS40L26 haptic driver
