5 CEC Pin Framework Error Injection
8 The CEC Pin Framework is a core CEC framework for CEC hardware that only
9 has low-level support for the CEC bus. Most hardware today will have
10 high-level CEC support where the hardware deals with driving the CEC bus,
12 allows you to connect the CEC pin to a GPIO on e.g. a Raspberry Pi and
13 you have now made a CEC adapter.
17 test how well CEC adapters can handle error conditions.
19 Currently only the cec-gpio driver (when the CEC line is directly
