d54a3fc6 - firmware: cs_dsp: Add mock regmap for KUnit testing

Thu, 12 Dec 2024 14:37:14 +0000

firmware: cs_dsp: Add mock regmap for KUnit testingAdd a mock regmap implementation to act as a simulated DSP for KUnittesting. This is built as a utility module so that it could be used byclients of cs_dsp to create a mock "DSP" for their own testing.cs_dsp interacts with the DSP only through registers. Most of theregister space of the DSP is RAM. ADSP cores have a small set of controlregisters. HALO Core DSPs have a much larger set of control registers butonly a small subset are used.Most writes are "blind" in the sense that cs_dsp does not expect toreceive any sort of response from the DSP. So there isn't any need toemulate a "DSP", only a set of registers that can be written and readback.The idea of the mock regmap is to use the cache to accumulate writeswhich can then be tested against the values that are expected to be inthe registers.Stray writes can be detected by dropping the cache entries for alladdresses that should have been written and then issuing a regcache_sync().If this causes bus writes it means there were writes to unexpectedregisters.Signed-off-by: Richard Fitzgerald Link: https://patch.msgid.link/20241212143725.1381013-2-rf@opensource.cirrus.comSigned-off-by: Mark Brown List of files: /linux-6.15/drivers/firmware/cirrus/Makefile

d7cfdf17 - firmware: cs_dsp: Rename KConfig symbol CS_DSP -> FW_CS_DSP

Thu, 24 Nov 2022 13:45:55 +0000

firmware: cs_dsp: Rename KConfig symbol CS_DSP -> FW_CS_DSPQualify the KConfig symbol for cs_dsp by adding a FW_ prefix so thatit is more explicit what is being referred to. This is preparation forusing the symbol to namespace the exports.Signed-off-by: Richard Fitzgerald Link: https://lore.kernel.org/r/20221124134556.3343784-2-rf@opensource.cirrus.comSigned-off-by: Mark Brown List of files: /linux-6.15/drivers/firmware/cirrus/Makefile

f6bc909e - firmware: cs_dsp: add driver to support firmware loading on Cirrus Logic DSPs

Mon, 13 Sep 2021 16:00:57 +0000

firmware: cs_dsp: add driver to support firmware loading on Cirrus Logic DSPswm_adsp originally provided firmware loading on some audio DSP and wasimplemented as an ASoC codec driver. However, the firmware loading nowcovers a wider range of DSP cores and peripherals containing them,beyond just audio. So it needs to be available to non-audio drivers. Allthe core firmware loading support has been moved into a new drivercs_dsp, leaving only the ASoC-specific parts in wm_adsp.Signed-off-by: Simon Trimmer Signed-off-by: Charles Keepax Link: https://lore.kernel.org/r/20210913160057.103842-17-simont@opensource.cirrus.comSigned-off-by: Mark Brown List of files: /linux-6.15/drivers/firmware/cirrus/Makefile
