Alexander Shishkin 1192918530 stm class: Add heartbeat stm source device
Heartbeat stm source may have multiple instances (for connecting to
different stm devices). Each instance will send a periodic test message
over its stm device when it is linked. This can be used for testing stm
class framework, stm device drivers or as a heartbeat over the stm link.

help
A System Trace Module (STM) is a device exporting data in System
Trace Protocol (STP) format as defined by MIPI STP standards.
Examples of such devices are Intel(R) Trace Hub and Coresight STM.
Say Y here to enable System Trace Module device support.

config STM_DUMMY
tristate "Dummy STM driver"
help
This is a simple dummy device that pretends to be an stm device
and discards your data. Use for stm class testing.
If you don't know what this is, say N.
config STM_SOURCE_CONSOLE
tristate "Kernel console over STM devices"
help
This is a kernel space trace source that sends kernel log
messages to trace hosts over STM devices.
If you want to send kernel console messages over STM devices,
say Y.
config STM_SOURCE_HEARTBEAT
tristate "Heartbeat over STM devices"
help
This is a kernel space trace source that sends periodic
heartbeat messages to trace hosts over STM devices. It is
also useful for testing stm class drivers and the stm class
framework itself.
If you want to send heartbeat messages over STM devices,
say Y.
