2023-09-15ASoC: amd: ps: Fix -Wformat-truncation warningTakashi Iwai1-1/+1
The compile warning with -Wformat-truncation at sdw_amd_scan_controller() is false-positive; the max loop size is AMD_SDW_MAX_MANAGERS (= 2), hence it fits with the given size. For suppressing the warning, replace snprintf() with scnprintf(). As stated in the above, truncation doesn't matter.

There's several things here that will really help my CI.
2023-07-10ASoC: amd: ps-sdw-dma: Convert to platform remove callback returning voidUwe Kleine-König1-3/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-07-10ASoC: amd: ps: Fix extraneous error messagesMario Limonciello1-2/+2
On Pink Sardine machines that don't have SdW controllers in use, the property `mipi-sdw-manager-list` won't exist. There is no point in showing an error to a user when this situation is encountered. Furthermore if the machine doesn't have a DMIC connected to the ACP, there may be no platform devices created either. Downgrade the associated message to debug.

2022-08-30ASoC: amd: add platform devices for acp6.2 pdm driver and dmic driverSyed Saba Kareem2-2/+102
ACP6.2 IP has PDM decoder block. Create a platform device for it, so that the PDM platform driver can be bound to this device. Pass PCI resources like MMIO to this platform device. Create a platform device for generic dmic codec driver.
