ASoC: SOF: imx9: use SCMI API for LM management

2025-11-18T18:54:12+00:00

Linux supports NXP's LMM SCMI protocol so switch to using the appropriate API. The SIPs were intended to act as placeholders until the support for said protocol was upstreamed. The underlying CPU protocol command from IMX_SIP_SRC_M_RESET_ADDR_SET is replaced by a LMM protocol command with the same effect (i.e. setting the boot address) since using the CPU protocol would require additional permissions (which TF-A already had). Apart from this, the SIPs are replaced by their equivalent Linux LMM commands.

ASoC: SOF: imx: Fix devm_ioremap_resource check

2025-09-02T11:51:32+00:00

devm_ioremap_resource does not return NULL on error but an error pointer so we need to use IS_ERR to check the return code. While at it also pass the error code to dev_err_probe to improve logging.

ASoC: SOF: imx: Remove the use of dev_err_probe()

The dev_err_probe() doesn't do anything when error is '-ENOMEM'. Therefore, remove the useless call to dev_err_probe(), and just return the value instead. Signed-off-by: Xichao Zhao Reviewed-by: Laurentiu Mihalcea Message-ID: <20250819112654.588527-1-zhao.xichao@vivo.com> Signed-off-by: Mark Brown

ASoC: SOF: imx: Remove error print for devm_add_action_or_reset()

2025-08-10T20:09:14+00:00

When `devm_add_action_or_reset()` fails, it is due to a failed memory allocation and will thus return `-ENOMEM`. `dev_err_probe()` doesn't do anything when error is `-ENOMEM`. Therefore, remove the useless call to `dev_err_probe()` when `devm_add_action_or_reset()` fails, and just return the value instead.

ASoC: SOF: imx8: add core shutdown operation for imx8/imx8x

2025-06-16T12:26:13+00:00

Currently, the DSP core from i.MX8QM/i.MX8QXP is able to operate while the firmware image is being loaded. Because of this, the DSP may change the content of the firmware data just after it was loaded, thus leading to the data having unexpected values when the DSP is reset (via run()). Fix this by implementing the core_shutdown() operation that will put the DSP in stall during suspend(). The stall will be removed during the run() opertion, thus guaranteeing that the DSP core will not be able to run while the firmware image is being loaded.

ASoC: SOF: imx8m: Use reset controller API to control the DSP

2025-05-05T23:48:15+00:00

DSP on i.MX8MP doesn't have a direct reset line so according to hardware design team in order to handle assert/deassert/reset functionality we need to use a combination of control bits from two modules. Audio block control module for Run/Stall control of the DSP and DAP module in order to do software reset. In a first step, for i.MX8MP we are switching on using the reset controller API to handle the DSP Run/Stall bits i.MX8MP. This comes with the advantage of offering a better probe ordering and a more natural way of abstracting the Audio block control bits.
