This patchset provides the Freescale PAMU (Peripheral Access =
Management Unit) driver
and the corresponding IOMMU API implementation. PAMU is the IOMMU =
present on Freescale
QorIQ platforms. PAMU can authorize memory access, remap the memory =
address, and remap=20
the I/O transaction type.

This set consists of the following patches:
1. Addition of new field in the device (powerpc) archdata structure =
for storing iommu domain information
pointer. This pointer is stored when the device is attached to a =
particular iommu domain.
2. Addition of domain attributes required by the PAMU driver IOMMU =
API.
3. PAMU driver and IOMMU API implementation.

Varun Sethi (3):
Store iommu domain information pointer in archdata.
Add iommu domain attributes required by fsl PAMU driver.
FSL PAMU driver and IOMMU API implementation.

I assume that another patch series will add device tree binding spec and =
update device trees for SoCs with PAMU?
