From 14055b5a3a23204c4702ae5d3f2a819ee081ce33 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Wed, 17 Nov 2021 13:22:54 +0000 Subject: firmware: cs_dsp: Add pre_run callback The code already has a post_run callback, add a matching pre_run callback to the client_ops that is called before execution is started. This callback provides a convenient place for the client code to set DSP controls or hardware that requires configuration before the DSP core actually starts execution. Note that placing this callback before cs_dsp_coeff_sync_controls is important to ensure that any control values are then correctly synced out to the chip.
