Subject: [PATCH v4 0/2] ASoC: Add codec driver for Cirrus Logic CS48L32 DSP

formance low-power audio DSP with analog and
PDM digital inputs and support for low-power always-on voice-trigger
functionality.

This series adds the devicetree bindings and the ASoC codec driver.

Changes in V4:
- Removed bogus updates to MAINTAINERS that were leftover from an
  older version of this code that had other files that are now deleted.

Changes in V3:
- Remove reference in yaml to obsolete gpio.txt.

Changes in V2:
- Remove bogus use of 'i' local variable in dev_dbg() statement in
  cs48l32_init_inputs()
