Pull char / misc driver updates from Greg KH:
 "Here is the "large" pull request for char and misc and other assorted
  smaller driver subsystems for 5.3-rc1.

  It seems that this tree is becoming the funnel point of lots of
  smaller driver subsystems, which is fine for me, but that's why it is
  getting larger over time and does not just contain stuff under
  drivers/char/ and drivers/misc.

  Lots of small updates all over the place here from different driver
  subsystems:
   - habana driver updates
   - coresight driver updates
   - documentation file movements and updates
   - Android binder fixes and updates
   - extcon driver updates
   - google firmware driver updates
   - fsi driver updates
   - smaller misc and char driver updates
   - soundwire driver updates
   - nvmem driver updates
   - w1 driver fixes

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

* Xilinx SDFEC(16nm) IP *
The Soft Decision Forward Error Correction (SDFEC) Engine is a Hard IP block
which provides high-throughput LDPC and Turbo Code implementations.
The LDPC decode & encode functionality is capable of covering a range of
customer specified Quasi-cyclic (QC) codes. The Turbo decode functionality
principally covers codes used by LTE. The FEC Engine offers significant
power and area savings versus implementations done in the FPGA fabric.
Required properties:
- compatible: Must be "xlnx,sd-fec-1.1"
- clock-names : List of input clock names from the following:
- "core_clk", Main processing clock for processing core (required)
- "s_axi_aclk", AXI4-Lite memory-mapped slave interface clock (required)
- "s_axis_din_aclk", DIN AXI4-Stream Slave interface clock (optional)
- "s_axis_din_words-aclk", DIN_WORDS AXI4-Stream Slave interface clock (optional)
- "s_axis_ctrl_aclk", Control input AXI4-Stream Slave interface clock (optional)

- "m_axis_dout_words_aclk", DOUT_WORDS AXI4-Stream Master interface clock (optional)
- "m_axis_status_aclk", Status output AXI4-Stream Master interface clock (optional)
- clocks : Clock phandles (see clock_bindings.txt for details).
- reg: Should contain Xilinx SDFEC 16nm Hardened IP block registers
location and length.
- xlnx,sdfec-code : Should contain "ldpc" or "turbo" to describe the codes
being used.
- xlnx,sdfec-din-words : A value 0 indicates that the DIN_WORDS interface is
driven with a fixed value and is not present on the device, a value of 1
configures the DIN_WORDS to be block based, while a value of 2 configures the
DIN_WORDS input to be supplied for each AXI transaction.
- xlnx,sdfec-din-width : Configures the DIN AXI stream where a value of 1
configures a width of "1x128b", 2 a width of "2x128b" and 4 configures a width
of "4x128b".
- xlnx,sdfec-dout-words : A value 0 indicates that the DOUT_WORDS interface is

MMIO register bitfield-based multiplexer controller bindings
Define register bitfields to be used to control multiplexers. The parent
device tree node must be a syscon node to provide register access.
Required properties:
- compatible : "mmio-mux"
- #mux-control-cells : <1>
- mux-reg-masks : an array of register offset and pre-shifted bitfield mask
pairs, each describing a single mux control.
* Standard mux-controller bindings as decribed in mux-controller.txt
Optional properties:
- idle-states : if present, the state the muxes will have when idle. The
special state MUX_IDLE_AS_IS is the default.
The multiplexer state of each multiplexer is defined as the value of the
bitfield described by the corresponding register offset and bitfield mask pair
in the mux-reg-masks array, accessed through the parent syscon.
