Merge tag 'char-misc-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc and other driver subsystem updates from Greg KH:
 "Here is the large set of driver changes for char/misc drivers and
  other smaller driver subsystems that flow through this git tree.

  Included in here are:

   - New IIO drivers and features and improvments in that subsystem

   - New hwtracing drivers and additions to that subsystem

   - lots of interconnect changes and new drivers as that subsystem
     seems under very active development recently. This required also
     merging in the icc subsystem changes through this tree.

   - FPGA driver updates

   - counter subsystem and driver updates

   - MHI driver updates

   - nvmem driver updates

   - documentation updates

   - Other smaller driver updates and fixes, full details in the
     shortlog

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

+description: |
+  TPDAs are responsible for packetization and timestamping of data sets
+  utilizing the MIPI STPv2 packet protocol. Pulling data sets from one or
+  more attached TPDM and pushing the resultant (packetized) data out a
+  master ATB interface. Performing an arbitrated ATB interleaving (funneling)
+  task for free-flowing data from TPDM (i.e. CMB and DSB data set flows).
+
+  There is no strict binding between TPDM and TPDA. TPDA can have multiple
+  TPDMs connect to it. But There must be only one TPDA in the path from the
+  TPDM source to TMC sink. TPDM can directly connect to TPDA's inport or
+  connect to funnel which will connect to TPDA's inport.
+
+  We can use the commands are similar to the below to validate TPDMs.
+  Enable coresight sink first.
+
+  echo 1 > /sys/bus/coresight/devices/tmc_etf0/enable_sink
+  echo 1 > /sys/bus/coresight/devices/tpdm0/enable_source
+  echo 1 > /sys/bus/coresight/devices/tpdm0/integration_test
+  echo 2 > /sys/bus/coresight/devices/tpdm0/integration_test
+
+  The test data will be collected in the coresight sink which is enabled.
+  If rwp register of the sink is keeping updating when do integration_test
+  (by cat tmc_etf0/mgmt/rwp), it means there is data generated from TPDM
+  to sink.

+description: |
+  The TPDM or Monitor serves as data collection component for various dataset
+  types specified in the QPMDA spec. It covers Implementation defined ((ImplDef),
+  Basic Counts (BC), Tenure Counts (TC), Continuous Multi-Bit (CMB), and Discrete
+  Single Bit (DSB). It performs data collection in the data producing clock
+  domain and transfers it to the data collection time domain, generally ATB
+  clock domain.
+
+  The primary use case of the TPDM is to collect data from different data
+  sources and send it to a TPDA for packetization, timestamping, and funneling.
