[PATCH 13/16] ASoC: wm_adsp: move firmware loading to client
Simon Trimmer
simont at opensource.cirrus.com
Mon Sep 13 18:00:54 CEST 2021
This is preparation for moving the generic DSP support out of ASoC.
Passing the firmware as parameters into the power_up functions
simplifies the generic code that will be moved out of wm_adsp.
