Just a nit regarding the commit explanation.

From http://www.uefi.org/sites/default/files/resources/ACPI_6.0.pdf,
section 6.2.17 _CCA states that ARM platforms require ACPI _CCA
object to be specified for DMA-cabpable devices. This patch introduces
ACPI_MUST_HAVE_CCA in arm64 Kconfig to specify such requirement.

s/ACPI_MUST_HAVE_CCA/ACPI_CCA_REQUIRED/.

Ie, update the commit explanation to match the change introduced in V2.

In case _CCA is missing, arm64 would assign dummy_dma_ops
to disable DMA capability of the device.

Thanks,
