2019-12-29Add virtual sllin support and LIN bridging to CAN for demosScott Murray1-0/+7
To enable seeing the steering wheel LIN messages on the cluster board for the planned CES demo, a systemd unit that wraps the use of candump in bridging mode is added when the agl-cluster-support feature is enabled. To make sure that the sllin0 interface is always available for testing without the specific demo LIN hardware, a vcan interface is set up as sllin0 when the ttyUSB0 device representing the serial adapter for the LIN transceiver is not present. Since this virtual sllin0 interface is very useful for general testing of the steering wheel event support up through the low-can and signal-composer stack, it has not been hidden behind agl-cluster-demo-support.

2019-11-06Update LIN demo to use lin-configScott Murray1-1/+6
Changes include: - Add patch to fix lin-config recipe build QA error. - Tweak lin-config recipe to install lin_config as executable. - Rework sllin-demo systemd unit and start_lin_demo.sh script to use lin_config with an appropriate configuration file that enables polling of the steering wheel adapter instead of just using ldattach.
