This patch set adds support for m4u(Multimedia Memory Management Unit),
Currently it only support the m4u with 2 levels of pagetable on mt8173.
It's based on Robin Murphy's latest ARM64 DMA-v6[1]. The dsti is based
on MTK clock patch[2].

If the device itself reports ATS in its PCIe capabilities, but the BIOS
neglects to provide an ATSR structure to indicate that the root port can
also cope, then assume the latter is lying.

This provides basic PASID support for endpoint devices, tested with a
version of the i915 driver.
A given process can bind to only one device per IOMMU for now. Making
that more generic isn't particularly difficult but isn't needed yet, and
can come later once the basic functionality is stable.

As long as we use an identity mapping to work around the worst of the
hardware bugs which caused us to defeature it and change the definition
of the capability bit, we *can* use PASID support on the devices which
advertised it in bit 28 of the Extended Capability Register.
Allow people to do so wi
This patch set enables PASID support for the Intel IOMMU, along with
page request support.
Like its AMD counterpart, it exposes an IOMMU-specific API. I believe
we'll have a session at the Kernel Summit later this month in which we
can work out a generic API which will cover the two (now) existing
Current is using !flags, and we are going to use
IORESOURCE_DISABLED instead of clearing resource flags.
Let's convert all !flags to helper function resource_disabled().
resource_disabled will check !flags and IORESOURCE_DISABLED both.

Despite being a platform device, the SMMUv3 is capable of signaling

enjoy faults being reported in a new and exciting way.
