Merge tag 'char-misc-5.15-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 driver changes for 5.15-rc1.

  Lots of different driver subsystems are being updated in here,
  notably:

   - mhi subsystem update

   - fpga subsystem update

   - coresight/hwtracing subsystem update

   - interconnect subsystem update

   - nvmem subsystem update

   - parport drivers update

   - phy subsystem update

   - soundwire subsystem update

  and there are some other char/misc drivers being updated as well:

   - binder driver additions

   - new misc drivers

   - lkdtm driver updates

   - mei driver updates

   - sram driver updates

   - other minor driver updates.

  Note, there are no habanalabs driver updates in this pull request,
  that will probably come later before -rc1 is out in a different
  request.

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

-TI AM654 SERDES
-
-Required properties:
- - compatible: Should be "ti,phy-am654-serdes"
- - reg : Address and length of the register set for the device.
- - #phy-cells: determine the number of cells that should be given in the
-	phandle while referencing this phy. Should be "2". The 1st cell
-	corresponds to the phy type (should be one of the types specified in
-	include/dt-bindings/phy/phy.h) and the 2nd cell should be the serdes
-	lane function.
-	If SERDES0 is referenced 2nd cell should be:
-		0 - USB3
-		1 - PCIe0 Lane0
-		2 - ICSS2 SGMII Lane0
-	If SERDES1 is referenced 2nd cell should be:
-		0 - PCIe1 Lane0
-		1 - PCIe0 Lane1
-		2 - ICSS2 SGMII Lane1
- - power-domains: As documented by the generic PM domain bindings in
-	Documentation/devicetree/bindings/power/power_domain.txt.
- - clocks: List of clock-specifiers representing the input to the SERDES.
-	Should have 3 items representing the left input clock, external
-	reference clock and right input clock in that order.
- - clock-output-names: List of clock names for each of the clock outputs of
-	SERDES. Should have 3 items for CMU reference clock,
-	left output clock and right output clock in that order.
- - assigned-clocks: As defined in
-	Documentation/devicetree/bindings/clock/clock-bindings.txt
- - assigned-clock-parents: As defined in
-	Documentation/devicetree/bindings/clock/clock-bindings.txt
- - #clock-cells: Should be <1> to choose between the 3 output clocks.
-	Defined in Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-   The following macros are defined in dt-bindings/phy/phy-am654-serdes.h
-   for selecting the correct reference clock. This can be used while
-   specifying the clocks created by SERDES.
-	=> AM654_SERDES_CMU_REFCLK
-	=> AM654_SERDES_LO_REFCLK
-	=> AM654_SERDES_RO_REFCLK
-
- - mux-controls: Phandle to the multiplexer that is used to select the lane
-	function. See #phy-cells above to see the multiplex values.
-
-Example:
-
-Example for SERDES0 is given below. It has 3 clock inputs;
-left input reference clock as indicated by <&k3_clks 153 4>, external
-reference clock as indicated by <&k3_clks 153 1> and right input
-reference clock as indicated by <&serdes1 AM654_SERDES_LO_REFCLK>. (The
-right input of SERDES0 is connected to the left output of SERDES1).
-
-SERDES0 registers 3 clock outputs as indicated in clock-output-names. The
-first refers to the CMU reference clock, second refers to the left output
-reference clock and the third refers to the right output reference clock.
-
-The assigned-clocks and assigned-clock-parents is used here to set the
-parent of left input reference clock to MAINHSDIV_CLKOUT4 and parent of
-CMU reference clock to left input reference clock.

+CoreSight System Configuration Manager
+======================================
+
+    :Author:   Mike Leach <mike.leach@linaro.org>
+    :Date:     October 2020
+
+Introduction
+============
+
+The CoreSight System Configuration manager is an API that allows the
+programming of the CoreSight system with pre-defined configurations that
+can then be easily enabled from sysfs or perf.
+
+Many CoreSight components can be programmed in complex ways - especially ETMs.
+In addition, components can interact across the CoreSight system, often via
+the cross trigger components such as CTI and CTM. These system settings can
+be defined and enabled as named configurations.
+
+
+Basic Concepts
+==============
+
+This section introduces the basic concepts of a CoreSight system configuration.
+
+
+Features
+--------
+
+A feature is a named set of programming for a CoreSight device. The programming
+is device dependent, and can be defined in terms of absolute register values,
+resource usage and parameter values.
+
+The feature is defined using a descriptor. This descriptor is used to load onto
+a matching device, either when the feature is loaded into the system, or when the
+CoreSight device is registered with the configuration manager.
+
+The load process involves interpreting the descriptor into a set of register
+accesses in the driver - the resource usage and parameter descriptions
+translated into appropriate register accesses. This interpretation makes it easy
+and efficient for the feature to be programmed onto the device when required.
+
+The feature will not be active on the device until the feature is enabled, and
+the device itself is enabled. When the device is enabled then enabled features
+will be programmed into the device hardware.
+
+A feature is enabled as part of a configuration being enabled on the system.
+
+
+Parameter Value
+~~~~~~~~~~~~~~~
+
+A parameter value is a named value that may be set by the user prior to the
+feature being enabled that can adjust the behaviour of the operation programmed
+by the feature.
+
+For example, this could be a count value in a programmed operation that repeats
+at a given rate. When the feature is enabled then the current value of the
+parameter is used in programming the device.
+
+The feature descriptor defines a default value for a parameter, which is used
+if the user does not supply a new value.
+
+Users can update parameter values using the configfs API for the CoreSight
+system - which is described below.
+
+The current value of the parameter is loaded into the device when the feature
+is enabled on that device.
+
+
+Configurations
+--------------
+
+A configuration defines a set of features that are to be used in a trace
+session where the configuration is selected. For any trace session only one
+configuration may be selected.
+
+The features defined may be on any type of device that is registered
+to support system configuration. A configuration may select features to be
+enabled on a class of devices - i.e. any ETMv4, or specific devices, e.g. a
+specific CTI on the system.
+
+As with the feature, a descriptor is used to define the configuration.
+This will define the features that must be enabled as part of the configuration
+as well as any preset values that can be used to override default parameter
+values.
+
+
+Preset Values
+~~~~~~~~~~~~~
+
+Preset values are easily selectable sets of parameter values for the features
+that the configuration uses. The number of values in a single preset set, equals
+the sum of parameter values in the features used by the configuration.
+
+e.g. a configuration consists of 3 features, one has 2 parameters, one has
+a single parameter, and another has no parameters. A single preset set will
+therefore have 3 values.
+
+Presets are optionally defined by the configuration, up to 15 can be defined.
+If no preset is selected, then the parameter values defined in the feature
+are used as normal.
+
+
+Operation
+~~~~~~~~~
+
+The following steps take place in the operation of a configuration.
+
+1) In this example, the configuration is 'autofdo', which has an
+   associated feature 'strobing' that works on ETMv4 CoreSight Devices.
+
+2) The configuration is enabled. For example 'perf' may select the
+   configuration as part of its command line::
+
+    perf record -e cs_etm/autofdo/ myapp
+
+   which will enable the 'autofdo' configuration.
+
+3) perf starts tracing on the system. As each ETMv4 that perf uses for
+   trace is enabled,  the configuration manager will check if the ETMv4
+   has a feature that relates to the currently active configuration.
+   In this case 'strobing' is enabled & programmed into the ETMv4.
+
+4) When the ETMv4 is disabled, any registers marked as needing to be
+   saved will be read back.
+
+5) At the end of the perf session, the configuration will be disabled.
+
+
+Viewing Configurations and Features
+===================================
+
+The set of configurations and features that are currently loaded into the
+system can be viewed using the configfs API.
+
+Mount configfs as normal and the 'cs-syscfg' subsystem will appear::
+
+    $ ls /config
+    cs-syscfg  stp-policy
+
+This has two sub-directories::
+
+    $ cd cs-syscfg/
+    $ ls
+    configurations  features
+
+The system has the configuration 'autofdo' built in. It may be examined as
+follows::
+
+    $ cd configurations/
+    $ ls
+    autofdo
+    $ cd autofdo/
+    $ ls
+    description   preset1  preset3  preset5  preset7  preset9
+    feature_refs  preset2  preset4  preset6  preset8
+    $ cat description
+    Setup ETMs with strobing for autofdo
+    $ cat feature_refs
+    strobing
+
+Each preset declared has a preset<n> subdirectory declared. The values for
+the preset can be examined::
+
+    $ cat preset1/values
+    strobing.window = 0x1388 strobing.period = 0x2
+    $ cat preset2/values
+    strobing.window = 0x1388 strobing.period = 0x4
+
+The features referenced by the configuration can be examined in the features
+directory::
+
+    $ cd ../../features/strobing/
+    $ ls
+    description  matches  nr_params  params
+    $ cat description
+    Generate periodic trace capture windows.
+    parameter 'window': a number of CPU cycles (W)
+    parameter 'period': trace enabled for W cycles every period x W cycles
+    $ cat matches
+    SRC_ETMV4
+    $ cat nr_params
+    2
+
+Move to the params directory to examine and adjust parameters::
+
+    cd params
+    $ ls
+    period  window
+    $ cd period
+    $ ls
+    value
+    $ cat value
+    0x2710
+    # echo 15000 > value
+    # cat value
+    0x3a98
+
+Parameters adjusted in this way are reflected in all device instances that have
+loaded the feature.
+
+
+Using Configurations in perf
+============================
+
+The configurations loaded into the CoreSight configuration management are
+also declared in the perf 'cs_etm' event infrastructure so that they can
+be selected when running trace under perf::
+
+    $ ls /sys/devices/cs_etm
+    configurations  format  perf_event_mux_interval_ms  sinks  type
+    events  nr_addr_filters  power
+
+Key directories here are 'configurations' - which lists the loaded
+configurations, and 'events' - a generic perf directory which allows
+selection on the perf command line.::
+
+    $ ls configurations/
+    autofdo
+    $ cat configurations/autofdo
+    0xa7c3dddd
+
+As with the sinks entries, this provides a hash of the configuration name.
+The entry in the 'events' directory uses perfs built in syntax generator
+to substitute the syntax for the name when evaluating the command::
+
+    $ ls events/
+    autofdo
+    $ cat events/autofdo
+    configid=0xa7c3dddd
+
+The 'autofdo' configuration may be selected on the perf command line::
+
+    $ perf record -e cs_etm/autofdo/u --per-thread <application>
+
+A preset to override the current parameter values can also be selected::
+
+    $ perf record -e cs_etm/autofdo,preset=1/u --per-thread <application>
+
+When configurations are selected in this way, then the trace sink used is
+automatically selected.

+	  This option is only intended to be used for tests on a device

+	  topologies that differ from the actual hardware layout.
+	  This mockup device could be totally virtual but could also be a
+	  real physical one with one key restriction: it is not allowed by the
+	  SoundWire specification to be configured via a sideband mechanism and
+	  generate audio data for capture. However, nothing prevents such a
