Use the RTIO work queue to fake the i2c submit calls for drivers which haven't yet implemented the API. Applications can change the size of the work queue pool depending on how much traffic they have on the buses. Signed-off-by: Yuval Peress <peress@google.com>

/*

|
* We need to override fff's function signature away from a standard function pointer.
|
|
* By using std::function<> we're able to leverage capture variables since additional storage must
|
|
* be allocated for them. In the tests, we will include asserts in the lambda functions. This
|
|
* provides the ability to assert inside the lambda and get errors that map to a line within the
|
|
* test function. If we use plain function pointers, we have to move the expected value outside
|
|
* of the test function and make it a static global of the compilational unit.
|
|
*
|
|
* Example:
|
|
* @code
|
|
* const uint8_t expected_value = 40;
|
|
* my_function_fake.custom_fake = [&expected_value](uint8_t value) {
|
|
* zassert_equal(expected_value, value);
|
|
* };
|
|
* my_function(expected_value);
|
|
* @endcode
