Merge tag 'staging-4.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging/IIO fixes from Greg KH:
 "Here are a small number of staging and iio driver fixes for 4.16-rc2.

  The IIO fixes are all for reported things, and the android driver
  fixes also resolve some reported problems. The remaining fsl-mc
  Kconfig change resolves a build testing error that Arnd reported.

  All of these have been in linux-next with no reported issues"

staging: fsl-mc: fix build testing on x86

2018-02-16T16:50:09+00:00

Selecting GENERIC_MSI_IRQ_DOMAIN on x86 causes a compile-time error in
some configurations:

drivers/base/platform-msi.c:37:19: error: field 'arg' has incomplete type

On the other architectures, we are fine, but here we should have an additional
dependency on X86_LOCAL_APIC so we can get the PCI_MSI_IRQ_DOMAIN symbol.

irqchip/gic-v3: Ignore disabled ITS nodes

2018-02-16T13:47:58+00:00

On some platforms there's an ITS available but it's not enabled
because reading or writing the registers is denied by the
firmware. In fact, reading or writing them will cause the system
to reset. We could remove the node from DT in such a case, but
it's better to skip nodes that are marked as "disabled" in DT so
that we can describe the hardware that exists and use the status
property to indicate how the firmware has configured things.

staging: fsl-mc: Add SPDX license identifiers

2018-01-22T10:45:21+00:00

The fsl-mc bus and dpio driver files use a combination of GPL-2.0 and
GPL-2.0+ OR BSD-3-Clause licenses. Add SPDX tags and delete the full
license text, keeping the existing license for each file. Add GPL-2.0
for Kconfig / Makefile, where not present.

staging: fsl-mc: make function its_fsl_mc_msi_init static

2018-01-17T14:05:46+00:00

The function its_fsl_mc_msi_init is local to the source and does
not need to be in global scope, so make it static.

Cleans up sparse warning:
symbol 'its_fsl_mc_msi_init' was not declared. Should it be static?

staging: fsl-mc: Convert documentation to rst format

2018-01-17T14:05:02+00:00

Update the doc file to comply with the rst format.

It's not integrated into the documentation build structure yet,
since it's still located in drivers/staging.

staging: fsl-mc: Update include header

2018-01-16T15:14:40+00:00

With the declarations of its_fsl_mc_msi_init/cleanup() now removed
from fsl-mc-private.h, irq-gic-v3-its-fsl-mc-msi.c only needs a
couple of definitions from mc.h, so include that header directly.

staging: fsl-mc: Remove unnecessary dependency

2018-01-16T15:14:39+00:00

The function that enables fsl-mc msi interrupts doesn't need
to be explicitly called from the fsl-mc bus driver initialization
routine.

Mark it to be independently called at system init; this is in line
with how things are handled by other GICv3 irqchip users.

Due to this change we now have an unused cleanup function, so
remove it.
