[alsa-devel] [PATCH 1/3] ASoC: da7219: Convert driver to use generic device/fwnode functions
Adam Thomson

Fri Jun 10 12:16:06 CEST 2016
This change converts the driver from using the of_* functions to using
the device_* and fwnode_* functions for accssing DT related data.
This is in preparation for updates to support ACPI based initialisation.
