Subject: [PATCH 0/4] iommu/fsl: Freescale PAMU driver and IOMMU API implementation.
Newsgroups: gmane.linux.kernel
Date: Friday 14th December 2012 13:51:51 UTC (over 4 years ago)
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 
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. Add PAMU bypass enable register to the ccsr_guts structure.
3. Addition of domain attributes required by the PAMU driver IOMMU API.
4. PAMU driver and IOMMU API implementation.

This patch set is based on the next branch of the iommu git tree maintained
by Joerg.

Varun Sethi (4):
  store iommu domain info in device arch data.
  add pamu bypass enable register to guts.
  Add iommu attributes for PAMU
  FSL PAMU driver.
