2016-04-08stm class: stm_heartbeat: Make nr_devs parameter read-onlyAlexander Shishkin1-9/+5

2016-02-20stm class: Add heartbeat stm source deviceAlexander Shishkin1-0/+130
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.
