Modules
	Bit manipulation
	This file contains common (or not) bitwise operations.

	Compiler
	This file contains macros designed to be used with the compiler.

	Constants
	Common known constants.

	Mapping
	These macros allow to map another macro or function onto a list of arguments.

	Mathematical operations
	Collection of macros to perform simple and common math operations.

Macros
#define	container_of(_ptr, _struct, _field) ((_struct )(((void )_ptr) - offsetof(_struct, _field)))
	Cast a member of a structure out to the containing structure. More...

#define	MSB(_x) ((_x) >> 8)
	Retrieve the most significant bytes from 16bit integer.

#define	LSB(_x) ((_x)&0xFF)
	Retrieve the less significant bytes from 16bit integer.

#define	WAIT_FOR(_cond)
	Loop infinitely while the condition `_cond` is not met.

#define	INFINITE_LOOP() while (true)
	Loop infinitely.

#define	BETWEEN(_x, _l, _h) ((_l) < (_x) && (_x) < (_h))
	Check if x is strictly between l and h (l < x < h)

#define	IN_RANGE(_x, _l, _h) ((_l) <= (_x) && (_x) <= (_h))
	Check if x is between l and h (l <= x <= h)

#define	RANGES_OVERLAP(_start1, _end1, _start2, _end2) ((_start1) <= (_end2) && (_end1) >= (_start2))
	Check if two ranges overlap with each other.

#define	UNUSED(_x) (void)(_x);
	Avoid compiler warning when not using a symbol.

#define	ARRAY_SIZE(_arr) (sizeof(_arr) / sizeof(_arr[0]))
	Compute the number of element inside an array at compile time.

#define	RETURN_CMP(_x, _y)
	Retun the result of a comparison, similar to what's returned by strcmp.

#define	stringify(_x) stringify1(_x)
	Preprocess an expression into a raw string.
