|
|
* Description:
|
|
* Initialize a quadrature encoder interface. This function must be called

|
* from board-specific logic..
|
|
*
|
|
* Input Parameters:
|
|
* devpath - The full path to the driver to register. E.g., "/dev/qe0"
|
|
* tc - The timer counter number to used. 'tc' must be an element of
|
|
* {0,1,2,3}
|
|
*
|
|
* Returned Value:
|
|
* Zero on success; A negated errno value is returned on failure.
