The perforce version of the MODS kernel driver
does not pull in any of the Tegra specific driver
functions. This prevents the perforce driver
from being compiled on any Tegra system or non
Tegra system with CONFIG_ARCH_TEGRA=y.
To allow the perforce driver to be compiled
replace CONFIG_ARCH_TEGRA with MODS_HAS_TEGRA
which is set based on CONFIG_ARCH_TEGRA in git
but left unset in perforce.

To allocate larger buffer, MODS code is allocating noncontiguous pages
and then calls dma buffer api to do smmu mapping to get a continuous
iova address. This change will fix the error when the scatterlist's
dma address is 0xffffffffffffffff, skip checking the sg since it's
already merged to the head node.

Summary: Previously mods stored handles for both
clocks and resets in the same list. This meant
reset signals that didn't have a corresponding
clock signal could not be toggled. This change
adds a separate list of structures to handle
resets and decouple it from the clock handling.

In git, we have moved this header to uapi directory, so that it can be
installed with the headers_install target. It now has to follow
guidelines of well-formed headers usable in userspace programs.
* Update SPDX license header.

This change will add smmu mapping/unmapping support for MODS
allocated memory buffer by using kernel smmu api dma_map_sg_attrs()
and dma_unmap_sg_attrs()
1. new IOCTL MODS_ESC_IOMMU_DMA_MAP_MEMORY and
MODS_ESC_IOMMU_DMA_UNMAP_MEMORY is added to do smmu mapping/unmapping
and get smmu mapped address for MODS allocated buffers;
2. a platform device and driver is added to match mods smmu sid in dtb,
the device is used to do smmu mapping/unampping; and mods smmu devices
are added in dtb to match with the driver with smmu config

* Add new cl_* macros for printing client-specific messages.
This adds client index to messages in code which is called from
user space. This makes it easier to diagnose errors when multiple
clients (processes) open the driver.
* Use kernel print levels appropriate to messages being printed.
* Print process pid when opening the driver.
* Print information about access token being set or released.
* Print information about PCI devices being enabled or disabled.
PCI device enablement is tied to the driver getting ownership
of the device. It also prevents multiple MODS instances from
owning the same PCI device.
* Print info about device DMA mask, print device DMA mask when DMA
mapping fails.
* Print more info about SRIOV actions.
* Disable SRIOV when the driver is being closed by the process
which enables SRIOV. Leaving SRIOV enabled when disabling PCI
device is an error and leads to stale functions, unusable on
subsequent MODS runs.
* Clean up log messages in a few places.

Summary: Support to hook mods interrupts
for tegra mods devices was broken due to
gpu-mods changes that went uncaught in sanity.
This change modifies the kernel to allow the tegra
code paths to work again. This change also adds
support to map irq numbers to gpio input pins
to expand functionality in the irq framework.

will overflow the local segment_size when accumulating
sg->length to it at line "segment_size += sg->length".
Since segment_size of MODS_DMABUF_GET_PHYSICAL_ADDRESS
structure is defined in u64 type, this patch fixes the
bug by changing the local varible to u64 as well.
