[PATCH v4 00/12] Add Vangogh ACP ASoC driver
This adds an ASoC driver for the ACP (Audio CoProcessor) block on AMD Vangogh APU.
Changes since v3: - Fixed typo errors - Fixed platform devices unregister logic - Updated acp resources count with macro value - updated ACP5x_I2S_MODE macro value to avoid unregistering platform devices for other ACP audio configurations in driver remove callback - Fixed error handling - Fixed indentation issues in irq handler - Add __maybe_unused for PM functions
Changes since v2: - remove extra stuff from Make file
Changes since v1: - add comment for acp_readl() & acp_writel() API's in common header file. - add amd: tag in commit message - modify condition check in acp5x_power_on() - removed acp_power_gating flag related code - drop acp5x_audio_remove() API - use single flag for handling irq status - fixed indetation issue and used dev_err instead of pr_err - drop acp5x_dai_remove() API - use SND_SOC_DAIFMT_CLOCK_PROVIDER_MASK - use PM related Macros in ACP PCI driver - use PM related Macros in ACP DMA driver - remove extra line in Make file

This option enables ACP v5.x support on AMD platformBy enabling this flag build will trigger for ACP PCI driver,ACP DMA drvier, CPU DAI driver.

This adds an ASoC driver for the ACP (Audio CoProcessor) block on AMD Vangogh APU.
Thanks for the update. I added a couple of minor comments on the v4, this looks mostly good now so feel free to add my tag in the following version
