[RFC PATCH v2 09/15] drivers: iommu: arm-smmu-v3: split probe functions into DT/generic portions

On Tue, Jun 07, 2016 at 02:31:04PM +0100, Lorenzo Pieralisi wrote:

Current ARM SMMUv3 probe functions intermingle HW and DT probing in the
initialization functions to detect and programme the ARM SMMU v3 driver
features. In order to allow probing the ARM SMMUv3 with other firmwares
than DT, this patch splits the ARM SMMUv3 init functions into DT and HW
specific portions so that other FW interfaces (ie ACPI) can reuse the HW
probing functions and skip the DT portion accordingly.

This patch implements no functional change, only code reshuffling.
