Char/Misc driver patches for 4.19-rc1

Browse source 
Here is the bit set of char/misc drivers for 4.19-rc1
 
 There is a lot here, much more than normal, seems like everyone is
 writing new driver subsystems these days...  Anyway, major things here
 are:
 	- new FSI driver subsystem, yet-another-powerpc low-level
 	  hardware bus
 	- gnss, finally an in-kernel GPS subsystem to try to tame all of
 	  the crazy out-of-tree drivers that have been floating around
 	  for years, combined with some really hacky userspace
 	  implementations.  This is only for GNSS receivers, but you
 	  have to start somewhere, and this is great to see.
 Other than that, there are new slimbus drivers, new coresight drivers,
 new fpga drivers, and loads of DT bindings for all of these and existing
 drivers.
 
 Full details of everything is in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.

Description: Read fpga manager status as a string.
If FPGA programming operation fails, it could be caused by crc
error or incompatible bitstream image. The intent of this
interface is to provide more detailed information for FPGA
programming errors to userspace. This is a list of strings for
the supported status.
* reconfig operation error - invalid operations detected by
reconfiguration hardware.
e.g. start reconfiguration
with errors not cleared
* reconfig CRC error - CRC error detected by
reconfiguration hardware.
* reconfig incompatible image - reconfiguration image is
incompatible with hardware
* reconfig IP protocol error - protocol errors detected by
reconfiguration hardware
* reconfig fifo overflow error - FIFO overflow detected by
reconfiguration hardware
