[PATCH 16/16] firmware: cs_dsp: add driver to support firmware loading on Cirrus Logic DSPs

From: Simon Trimmer
Date: Mon Sep 13 2021 - 12:02:39 EST

Next message: David Laight: "RE: how many memset(,0,) calls in kernel ?"
Previous message: Simon Trimmer: "[PATCH 14/16] ASoC: wm_adsp: Split out struct cs_dsp from struct wm_adsp"
In reply to: Simon Trimmer: "[PATCH 14/16] ASoC: wm_adsp: Split out struct cs_dsp from struct wm_adsp"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

wm_adsp originally provided firmware loading on some audio DSP and was
implemented as an ASoC codec driver. However, the firmware loading now
covers a wider range of DSP cores and peripherals containing them,
beyond just audio. So it needs to be available to non-audio drivers. All
the core firmware loading support has been moved into a new driver
cs_dsp, leaving only the ASoC-specific parts in wm_adsp.
