8aad6c65fc MODS: add mods_tegra_dma platform driver 
For upstream dma engine slave_id in <struct dma_slave_config> is obsolete.
The Correct way to specify slave_id is
to call dma_request_chan API along with device name defined in dts node.

mods_tegra_dma: mods_tegra_dma {
    compatible = "nvidia,mods_tegra_dma";
    dmas = <&gpcdma 15>, <&gpcdma 16>;
    dma-names = "spi1_rx", "spi2_tx";
    status = "okay";
};

To keep kernel ABI compatibility,
add a new ioctl cmd MODS_ESC_DMA_REQUEST_HANDLE_2.
A new struct MODS_DMA_HANDLE_2 is used together with it.
A new function esc_mods_dma_request_channel_2 is implemented accordingly.

2ce330f11a misc: mods: Replace CONFIG_ARCH_TEGRA 
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.

62a67b00a8 Fix Smmu IOVA contiguous checking error 
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.

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.

b5b2def304 misc: mods: improve logging and fix SRIOV 
* 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.
