Merge series "Add reset-gpios handling for max98927" from Alejandro Tafalla <atafalla@dnyon.com>:
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
