Add complete driver support for the QST QMI8658 6-axis IMU sensor featuring 3-axis accelerometer and 3-axis gyroscope with I2C interface and uORB integration. Key features implemented: * Full I2C communication with configurable frequency (default 400kHz) * Multiple accelerometer ranges (±2g, ±4g, ±8g, ±16g) and ODR settings * Multiple gyroscope ranges (±16 to ±1024 dps) with high ODR support * Low-pass filter configuration for both sensors * Temperature sensing with 16-bit resolution * Self-test capability for both accelerometer and gyroscope * Calibration-on-demand support with offset registers * FIFO buffer management (framework ready) * Interrupt-driven and polling mode support * Complete uORB integration with sensor_accel and sensor_gyro topics Driver components added: * Core driver implementation (qmi8658_uorb.c) with register operations * Header file with register definitions and scale factors (qmi8658.h) * Kconfig options for driver configuration and polling mode * Build system integration (CMakeLists.txt, Make.defs) * Comprehensive documentation with API reference and usage examples The driver follows NuttX sensor framework conventions and provides robust error handling, mutex protection, and comprehensive debugging support through CONFIG_DEBUG_SENSORS.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
Contributing
If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
