[PATCH 04/12] ASoC: amd: create acp5x platform devices

[Vijendar Mukunda]

ACP5.x IP has multiple I2S controllers and DMA controller.
Create platform devices for I2S HS controller instance, I2S SP controller
instance and DMA contrller.
Pass PCI resources like MMIO, irq to these platform devices.

[PATCH V2 12/12] ASoC: amd: enable vangogh acp5x driver build

[Vijendar Mukunda]

Vangogh ACP5x drivers can be built by selecting necessary
kernel config option.
The patch enables build support of the same.

Looks like CONFIG_SND_SOC_AMD_VANGOGH_MACH is not selected by another
symbol and also not configurable in kconfig.

Is it missing a kconfig entry?

Actually, acp5x-nu8821-cs35l41.o can't be generated by my tree.  Which
tree is this series based on?  Is there another series that's a
