121  * @_arraytype: C type of the array elements
122  *
123  * Define device properties for a variable-length array _name.  A
124  * static property "len-arrayname" is defined. When the device creator
125  * sets this property to the desired length of array, further dynamic
126  * properties "arrayname[0]", "arrayname[1]", ...  are defined so the
127  * device creator can set the array element values. Setting the
128  * "len-arrayname" property more than once is an error.
129  *
130  * When the array length is set, the @_field member of the device
131  * struct is set to the array length, and @_arrayfield is set to point
132  * to (zero-initialised) memory allocated for the array.  For a zero
133  * length array, @_field will be set to 0 and @_arrayfield to NULL.
134  * It is the responsibility of the device deinit code to free the
135  * @_arrayfield memory.
