Hi, here is a patch-set to rename iommu_param to dev_iommu and establish it as a struct for generic per-device iommu-data. Also move the iommu_fwspec pointer from struct device into dev_iommu to have less iommu-related pointers in struct device. The bigger part of this patch-set moves the iommu_priv pointer from struct iommu_fwspec to dev_iommu, making is usable for iommu-drivers which do not

Hi, This series includes some pieces of fixes to complete the GK20A power on/off sequences and add the suspend/resume support. The patches 1/11 - 4/11 are based on the linux-next-20141219. The patches 5/11 - 11/11 are based on the branch "linux-3.19" of Ben Skeggs's tree (http://cgit.freedesktop.org/~darktama/nouveau). Thanks, Vince Vince Hsu (4): (linux-next-20141219) ARM:
