This patch adds PCI driver to bind to this device and get
PCI resources for Pink Sardine Platform.

Can't you just define offsets in header, without ACP62_PHY_BASE_ADDRESS?
Then you won't need to subtract the value here?
I mean like:
#define ACP_DMA_CNTL_0 0x0000
#define ACP_DMA_CNTL_1 0x0004
...
instead of
#define ACP_DMA_CNTL_0 0x1240000
#define ACP_DMA_CNTL_1 0x1240004
...
Seems a bit weird to me, to just define values with offset if it is not
needed...

Wrong indentation in assignment above?

This one is optional, but you could also use:
PCI_VDEVICE(AMD, ACP_DEVICE_ID)
which is bit shorter and at least to me seems a bit more readable.

It would be better if you passed the device in so messages like this
could be dev_err() rather than just pr_err().

In function before you just write decimal 1 and 0, and here and later in
patch you use hex values? Should probably be consistent.

Unnecessary comment? Called function name is already self explanatory,

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.

Add ACP6.2 irq handler for handling irq events for ACP IP.
Add pdm irq events handling.
Whenever audio data equal to the PDM watermark level are consumed,
interrupt is generated. Acknowledge the interrupt.

Fix indentation.
Also you can remove struct name, and access fields directly, so instead
of accessing somevariable.bcount.low, you would use somevariable.low, it
would probably be more readable.

Should probably kfree(runtime->private_data) in acp62_pdm_dma_close(),
otherwise won't there be a memory leak?

Could this be
depends on X86 || COMPILE_TEST
depends on PCI
to improve build coverage?
