Pull request overview
This PR updates the LED driver subsystem with bug fixes and adds two new LED driver implementations (PWM and Syscon). The changes address a critical string comparison bug and introduce a heartbeat blink pattern, while also improving memory allocation practices.
Key Changes:
- Fixed critical bug: corrected
rt_strncpytort_strncmpfor LED state matching - Added heartbeat-style LED blink pattern with configurable timing
- Introduced PWM-based LED driver with brightness control support
- Introduced Syscon (system controller) LED driver for register-bit controlled LEDs
- Improved memory allocation in GPIO LED driver using
rt_callocfor zero-initialization
