This patch refactors of_pci_dma_configure() into a more generic pci_dma_configure(), which can be reused by non-OF code. Then, it adds support for setting up PCI device DMA coherency from ACPI _CCA object that should normally be specified in the DSDT node of its PCI host bridge..

From the changelog, it sounds like you might be able to split this into two patches:

1. Refactor of_pci_dma_configure(), with no functional change
2. Add support for using _CCA

If that's possible, please do so to make this easier to review.

Yes, I can separate the patch out. This would mainly affect ACPI+PCI support for ARM64 (which is in progress).

Thanks,
