Artemis: cb: Support switch heartbeat for DVT (#1376)
Summary:
Description
- Support to get switch heartbeat to judge whether the switch is ready.
- Enable PWM/TACH to get Switch heartbeat RPM.
- Add patch to avoid utilizeing the busy-wait method in tach_aspeed_sample_fetch function.
Motivation
- Support to get switch heartbeat to judge whether the switch is ready.
Pull Request resolved: https://github.com/facebook/OpenBIC/pull/1376
Test Plan:
- Build code: Pass
- Get Switch heartbeat rpm: Pass
- Get Switch temperature sensor reading: Pass
- Check switch heartbeat work on Pre-DVT/EVT2 board: Pass
