+ * This is a model of the Maxim MAX1110/1111 ADC chip, which for QEMU
+ * is an SSI slave device. It has either 4 (max1110) or 8 (max1111)
+ * 8-bit ADC channels.
+ *
+ * QEMU interface:
+ * + GPIO inputs 0..3 (for max1110) or 0..7 (for max1111): set the value
+ * of each ADC input, as an unsigned 8-bit value
+ * + GPIO output 0: interrupt line
+ * + Properties "input0" to "input3" (max1110) or "input0" to "input7"
+ * (max1111): initial reset values for ADC inputs.
+ *
+ * Known bugs:
+ * + the interrupt line is not correctly implemented, and will never
+ * be lowered once it has been asserted.
