fsl-mc: msi: Added FSL-MC-specific member to the msi_desc's union

FSL-MC is a bus type different from PCI and platform, so it needs
its own member in the msi_desc's union.

irqdomain: Added domain bus token DOMAIN_BUS_FSL_MC_MSI

Since an FSL-MC bus is a new bus type that is neither PCI nor
PLATFORM, we need a new domain bus token to disambiguate the
IRQ domain for FSL-MC MSIs.

staging: drop kbuild workaround dummy module from top dir

This is essentially a revert of 86f69fe9c069dd8608d238581eea259caa1dfc99
("Staging: workaround build system bug"), but to call it a revert would
imply it was wrong -- rather it seems more like it is just no longer
required anymore.

It doesn't list the full details of the failing use case, but the most
obvious would appear to be a "make allnoconfig" that subsequently had set
just CONFIG_STAGING=y in the .config file, to give:

  paul@builder:~/git/linux-head$ grep STAGING ../staging-allno/.config
  CONFIG_STAGING=y
  # CONFIG_STAGING_MEDIA is not set
  # CONFIG_STAGING_BOARD is not set
  paul@builder:~/git/linux-head$

After building this .config (on ARM, just to be different), we see that
built-in.o is created, and the final vmlinux links OK:

  paul@builder:~/git/linux-head$ ls -l ../staging-allno/drivers/staging/built-in.o
  -rw-rw-r-- 1 paul paul 257 Nov 16 18:06 ../staging-allno/drivers/staging/built-in.o
  paul@builder:~/git/linux-head$ file ../staging-allno/drivers/staging/built-in.o
  ../staging-allno/drivers/staging/built-in.o: ELF 32-bit LSB relocatable, ARM, version 1, not stripped
  paul@builder:~/git/linux-head$ nm ../staging-allno/drivers/staging/built-in.o
  nm: ../staging-allno/drivers/staging/built-in.o: no symbols
  paul@builder:~/git/linux-head$ ls -l ../staging-allno/vmlinux
  -rwxrwxr-x 1 paul paul 1236326 Nov 16 18:07 ../staging-allno/vmlinux
  paul@builder:~/git/linux-head$

I also tested an "allmodconfig" and did not see any problems there
either.  Switching back to x86-64 and testing several things there didn't
show any issues either.  So it appears we do not need to carry the
workaround in tree any longer.

staging: comedi: ni_mio_common: add finite regeneration to dio output

This patch continues the implementation of reinterpreting stop_arg when
stop_src == TRIG_NONE for national instruments cdio output on e/m-series
devices.  This is part of a series of patches that allow a user to have a
specific buffer repeated as-is indefinitely.  The contents of the DMA
buffer can be left static or changed by the user via mmap access to the DMA
buffer.  If the contents are changed by the user, additional munging is not
performed by the driver and only a single call to
comedi_mark_buffer_written should be done.  The original behavior is
preserved when stop_arg == 0, as would be the prior use case.

As opposed to analog output, this patch is relatively simple.  First, the
digital output capabilities are much more limited/simple as compared to the
analog output device on NI e/m-series hardware, and second, this patch
relies on changes made with the earlier patch to accomplish limiting the
DMA buffer transfer.

staging: comedi: ni_mio_common: Cleans up/clarifies ni_ao_cmd

This patch implements ni_ao_cmd much more closely organized like NI MHDDK
examples and DAQ-STC pseudo-code.  Adds comments with some more specific
references to the DAQ-STC.

For stop_src==TRIG_NONE (continuous output mode of entire buffer), the
count for the UC counter was corrected to represent the maximum count
possible (0xffffff).  Prior behavior for stop_src=TRIG_NONE did not
actually follow the DAQ-STC.  Furthermore, stop_src==TRIG_NONE now
correctly uses code specialized for either m-series or e-series devices.

It should be noted that stop_src==TRIG_NONE does _not_ with this patch
(or with prior behavior in ni_mio_common) actually implement true
continuous output.  Rather, the output is simply configured to operate as a
single buffer output, but where the buffer is as large as is possible with
NI-STC hardware.

staging/ion: Add support to get ion handle from dma buf

Currently we can only import dma buf fd's to get ion_handle.
Adding support to import dma buf handles to support kernel
specific use cases.

An example use case is in linux platforms such as Tizen, in which
DRM-GEM is used for buffer management for graphics. It has gem_handle
corresponding to a buffer and uses gem_name for sharing the buffer
with other processes. However,it also uses dma_buf fd for 3d operations.
For wayland, there are multiple calls for gem_handle to dma_buf fd
conversion. So, we store dma_buf associated with buffer. But, there is
no api for getting ion_handle from dma_buf. This patch exposes api to
retrieve the ion handle from dma_buf for similar use cases. With this
patch, we can integrate ION within DRM-GEM for buffer management and
dma_buf sharing.
