* @index: Index of next pin groups
|
|
* @groups: pin groups
|
|
*
|
|
* This function is used by master to get pin groups specified
|
|
* by given pin Id. This API will return 6 pin groups with
|
|
* a single response. To get other pin groups, master should call
|
|
* same API in loop with new pin groups index till error is returned.
|
|
*
|
|
* E.g First call should have index 0 which will return pin groups
|
|
* 0, 1, 2, 3, 4 and 5. Next call, index should be 6 which will return
|
|
* pin groups 6, 7, 8, 9, 10 and 11 and so on.
|
|
*
|
|
* Return: Returns status, either success or error+reason.
