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

2025-11-18T18:54:12Z

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: of: Convert to EXPORT_DEV_PM_OPS()

2025-03-17T10:14:57Z

Use the newer EXPORT_DEV_PM_OPS() macro together with pm_ptr(). This optimizes slightly when CONFIG_PM is disabled, too.

ASoC: SOF: imx: add driver for the imx95 chip

2025-02-07T16:47:00Z

Add SOF support for the imx95 chip. Although the support is just for the imx95 chip, the driver is intended for all chips in the imx9 family. Note that the imx95 support could have just as easily been added to the imx8 platform driver but a new platform driver was created because the intention is to keep the families in separate drivers.
