Merge tag 'char-misc-4.20-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 set of char/misc patches for 4.20-rc1. Loads of things here, we have new code in all of these driver subsystems: - fpga - stm - extcon - nvmem - eeprom - hyper-v - gsmi - coresight - thunderbolt - vmw_balloon - goldfish - soundwire along with lots of fixes and minor changes to other small drivers. All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (245 commits) Documentation/security-bugs: Clarify treatment of embargoed information lib: Fix ia64 bootloader linkage MAINTAINERS: Clarify UIO vs UIOVEC maintainer docs/uio: fix a grammar nitpick docs: fpga: document programming fpgas using regions fpga: add devm_fpga_region_create fpga: bridge: add devm_fpga_bridge_create fpga: mgr: add devm_fpga_mgr_create hv_balloon: Replace spin_is_locked() with lockdep sgi-xp: Replace spin_is_locked() with lockdep eeprom: New ee1004 driver for DDR4 memory eeprom: at25: remove unneeded 'at25_remove' w1: IAD Register is yet readable trough iad sys file.

+What: /config/stp-policy/<device>:p_sys-t.<policy>/<node>/uuid
+Date: June 2018
+KernelVersion: 4.19
+Description:
+ UUID source identifier string, RW.
+ Default value is randomly generated at the mkdir <node> time.
+ Data coming from trace sources that use this <node> will be
+ tagged with this UUID in the MIPI SyS-T packet stream, to
+ allow the decoder to discern between different sources
+ within the same master/channel range, and identify the
+ higher level decoders that may be needed for each source.
+
+What: /config/stp-policy/<device>:p_sys-t.<policy>/<node>/do_len
+Date: June 2018
+KernelVersion: 4.19
+Description:
+ Include payload length in the MIPI SyS-T header, boolean.
+ If enabled, the SyS-T protocol encoder will include payload
+ length in each packet's metadata. This is normally redundant
+ if the underlying transport protocol supports marking message
+ boundaries (which STP does), so this is off by default.
+
+What: /config/stp-policy/<device>:p_sys-t.<policy>/<node>/ts_interval
+Date: June 2018
+KernelVersion: 4.19
+Description:
+ Time interval in milliseconds. Include a timestamp in the
+ MIPI SyS-T packet metadata, if this many milliseconds have
+ passed since the previous packet from this source. Zero is
+ the default and stands for "never send the timestamp".
+
+What: /config/stp-policy/<device>:p_sys-t.<policy>/<node>/clocksync_interval
+Date: June 2018
+KernelVersion: 4.19
+Description:
+ Time interval in milliseconds. Send a CLOCKSYNC packet if
+ this many milliseconds have passed since the previous
+ CLOCKSYNC packet from this source. Zero is the default and
+ stands for "never send the CLOCKSYNC". It makes sense to
+ use this option with sources that generate constant and/or
+ periodic data, like stm_heartbeat.

+What: /sys/bus/vmbus/devices/.../driver_override
+Date: August 2019
+Contact: Stephen Hemminger <sthemmin@microsoft.com>
+Description:
+ This file allows the driver for a device to be specified which
+ will override standard static and dynamic ID matching. When
+ specified, only a driver with a name matching the value written
+ to driver_override will have an opportunity to bind to the
+ device. The override is specified by writing a string to the
+ driver_override file (echo uio_hv_generic > driver_override) and
+ may be cleared with an empty string (echo > driver_override).
+ This returns the device to standard matching rules binding.
+ Writing to driver_override does not automatically unbind the
+ device from its current driver or make any attempt to
+ automatically load the specified driver. If no driver with a
+ matching name is currently loaded in the kernel, the device
+ will not bind to any driver. This also allows devices to
+ opt-out of driver binding using a driver_override name such as
+ "none". Only a single driver may be specified in the override,
+ there is no support for parsing delimiters.
