- * 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.

The MAX111X ADC device was used only by the XScale-based Zaurus machine types. Now they have all been removed, we can drop this device model too.
