can be expected. If simultaneous access is not possible the GPIOs will be
accessed sequentially.
The functions take three arguments:
The functions take four arguments:
* array_size - the number of array elements
* desc_array - an array of GPIO descriptors
* array_info - optional information obtained from gpiod_get_array()
* value_bitmap - a bitmap to store the GPIOs' values (get) or
a bitmap of values to assign to the GPIOs (set)
a bitmap of values to assign to the GPIOs (set)
The descriptor array can be obtained using the gpiod_get_array() function
or one of its variants. If the group of descriptors returned by that function
