[PATCH v1 00/21] coresight: allow to build coresight as modules

[Tingwei Zhang]

Allow to build coresight as modules. This gives developers the feasibility to
test their code without reboot.

This series is based on below two series.

 - "coresight: allow to build components as modules"
   https://lkml.org/lkml/2018/6/5/989
 - "coresight: make drivers modular"
   https://lkml.org/lkml/2020/1/17/468

This series adds the support to dynamically remove module when the device in
that module is enabled and used by some trace path. It disables all trace
paths with that device and release the trace path.

Kim Phillips (7):
  coresight: use IS_ENABLED for CONFIGs that may be modules
  coresight: allow etm3x to be built as a module
  coresight: allow etm4x to be built as a module
  coresight: allow etb to be built as a module
  coresight: allow tpiu to be built as a module
  coresight: allow tmc to be built as a module
  coresight: allow funnel and replicator drivers to be built as modules

Mian Yousaf Kaukab (4):
  coresight: export global symbols
  coresight: remove multiple init calls from funnel driver
  coresight: remove multiple init calls from replicator driver
  coresight: tmc-etr: add function to register catu ops

Tingwei Zhang (10):
  coresight: cpu_debug: add module name in Kconfig
  coresight: cpu_debug: define MODULE_DEVICE_TABLE
  coresight: add coresight prefix to barrier_pkt
  Allow to build coresight-stm as a module, for ease of development.
  coresight: cti: add function to register cti associate ops
  coresight: allow cti to be built as a module
  coresight: allow catu drivers to be built as modules
  coresight: disable trace path with device being removed
  coresight: allow the coresight core driver to be built as a module
  coresight: perf: clean up perf event on device unregister path
