Merge tag 'char-misc-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull char/misc driver updates from Greg KH:
 "Here is the big pull request for char/misc drivers for 4.16-rc1.

  There's a lot of stuff in here. Three new driver subsystems were added
  for various types of hardware busses:

   - siox
   - slimbus
   - soundwire

  as well as a new vboxguest subsystem for the VirtualBox hypervisor
  drivers.

  There's also big updates from the FPGA subsystem, lots of Android
  binder fixes, the usual handful of hyper-v updates, and lots of other
  smaller driver updates.

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

What:		/sys/bus/siox/devices/siox-X/active

KernelVersion:	4.16

Contact:	Gavin Schenk <g.schenk@eckelmann.de>, Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

Description:

		On reading represents the current state of the bus. If it

		contains a "0" the bus is stopped and connected devices are

		expected to not do anything because their watchdog triggered.

		When the file contains a "1" the bus is operated and periodically

		does a push-pull cycle to write and read data from the

		connected devices.

		When writing a "0" or "1" the bus moves to the described state.

KernelVersion:	4.16

Contact:	Gavin Schenk <g.schenk@eckelmann.de>, Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

Description:

		Write-only file. Write



			<type> <inbytes> <outbytes> <statustype>



		to add a new device dynamically. <type> is the name that is used to match

		to a driver (similar to the platform bus). <inbytes> and <outbytes> define

		the length of the input and output shift register in bytes respectively.

		<statustype> defines the 4 bit device type that is check to identify connection

		problems.

		The new device is added to the end of the existing chain.

KernelVersion:	4.16

Description:

		Write-only file. A single write removes the last device in the siox chain.

Contact:	Gavin Schenk <g.schenk@eckelmann.de>, Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

Description:

		Defines the interval between two poll cycles in nano seconds.

		Note this is rounded to jiffies on writing. On reading the current value

		is returned.

Description:

		Read-only value. "0" means the Yth device on siox bus X isn't "connected" i.e.

		communication with it is not ensured. "1" signals a working connection.
