74  *               will point to the array
75  * @_arrayprop: PropertyInfo defining what property the array elements have
76  * @_arraytype: C type of the array elements
77  *
78  * Define device properties for a variable-length array _name.  A
79  * static property "len-arrayname" is defined. When the device creator
80  * sets this property to the desired length of array, further dynamic
81  * properties "arrayname[0]", "arrayname[1]", ...  are defined so the
82  * device creator can set the array element values. Setting the
83  * "len-arrayname" property more than once is an error.
84  *
85  * When the array length is set, the @_field member of the device
86  * struct is set to the array length, and @_arrayfield is set to point
87  * to (zero-initialised) memory allocated for the array.  For a zero
88  * length array, @_field will be set to 0 and @_arrayfield to NULL.
89  * It is the responsibility of the device deinit code to free the
90  * @_arrayfield memory.
