Pull char/misc update part 2 from Greg KH:
 "Here is the "real" big set of char/misc driver patches for 5.2-rc1

  Loads of different driver subsystem stuff in here, all over the places:
   - thunderbolt driver updates
   - habanalabs driver updates
   - nvmem driver updates
   - extcon driver updates
   - intel_th driver updates
   - mei driver updates
   - coresight driver updates
   - soundwire driver cleanups and updates
   - fastrpc driver updates
   - other minor driver updates
   - chardev minor fixups

  Feels like this tree is getting to be a dumping ground of "small
  driver subsystems" these days. Which is fine with me, if it makes
  things easier for those subsystem maintainers.

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

4c5bb6eb40 intel_th: Only report useful IRQs to subdevices 
The only type of IRQ triggering event that is useful to us at the moment
is the "last block" interrupt of the MSU. This interrupt can only be
enabled via "MINTCTL" register that doesn't exist in earlier version of
the Intel TH.

Enumerate the presence of MINTCTL via per-device driver data structure
and only instantiate the IRQ resource for subdevices if this capability
is present.

7b7036d47c intel_th: pci: Use MSI interrupt signalling 
Since Intel TH is capable of MSI interrupt signalling, make use of it.
The way it works is, each of the 7 interrupt triggering events has its
own vector in this mode, as opposed to interrupt line delivery, where
all events are signalled via the same line. Failing to enable MSI, the
driver falls back to using an interrupt line.

62a593022c intel_th: Communicate IRQ via resource 
Currently, the IRQ is passed between the glue layers and the core as a
separate argument, while the MMIO resources are passed as resources.
This also limits the number of IRQs thus used to one, while the current
versions of Intel TH use a different MSI vector for each interrupt
triggering event, of which there are 7.

Change this to pass IRQ in the resources array.

db73a059de intel_th: Rework resource passing between glue layers and core 
Currently, MMIO resource numbers in the TH driver core correspond to
PCI BAR numbers, because in the beginning there was only the PCI glue
layer. This created some confusion when the ACPI glue layer was added.

To avoid confusion and remove glue-specific code from the driver core,
split the resource indices between core and glue layers and change the
API so that the driver core receives the MMIO resources in the same
fixed order. At the same time, make the IRQ always be a parameter to
intel_th_alloc() instead of sometimes passing it as a resource.

a0e7df335a intel_th: Perform time resync on capture start 
On some devices (TH 2.x devices at the moment), the internal time counter
is initially not synchronized to the global crystal clock, so the time
stamps it produces will not be useful. In this case, the driver needs
to force the time counter resync.

This applies the workaround to relevant devices.
