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.

Graph bindings for Coresight
|
||||
-------------------------------
|
||||
|
||||
Coresight components are interconnected to create a data path for the flow of
|
||||
trace data generated from the "sources" to their collection points "sink".
|
||||
Each coresight component must describe the "input" and "output" connections.
|
||||
The connections must be described via generic DT graph bindings as described
|
||||
by the "bindings/graph.txt", where each "port" along with an "endpoint"
|
||||
component represents a hardware port and the connection.
|
||||
|
||||
* All output ports must be listed inside a child node named "out-ports"
|
||||
* All input ports must be listed inside a child node named "in-ports".
|
||||
* Port address must match the hardware port number.
