Analog (ADC/DAC) Drivers

The NuttX analog drivers are split into two parts:

1. An "upper half", generic driver that provides the common analog interface to application level code, and
2. A "lower half", platform-specific driver that implements the low-level controls to implement the analog functionality.

• General header files for the NuttX analog drivers reside in include/nuttx/analog/. These header files includes both the application level interface to the analog driver as well as the interface between the "upper half" and "lower half" drivers.
• Common analog logic and share-able analog drivers reside in the drivers/analog/.
• Platform-specific drivers reside in arch/<architecture>/src/<hardware> directory for the specific processor <architecture> and for the specific <chip> analog peripheral devices.
