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