Subject: [PATCH v4 0/2] Add reset-gpios handling for max98927

The max98927 codec on some devices (i.e. Xiaomi Mi A2 Lite phone) requires
hardware-resetting the codec by driving a reset-gpio. This series adds
support for it through an optional reset-gpios property.

v4:
* Correctly assert/deassert the GPIO states
* Wait for the i2c port to be ready after reset
* Reset device when removed

v3:
* Fix indentation on the dev_err_probe line

v2:
* Use dev_err_probe instead of dev_err

Alejandro Tafalla (2):
  ASoC: max98927: Handle reset gpio when probing i2c
  dt-bindings: sound: max98927: Add reset-gpios optional property
