| H A D | fsl-mx25-tcq.txt | 1 Freescale mx25 TS conversion queue module
3 mx25 touchscreen conversion queue module which controls the ADC unit of the
7 - compatible: Should be "fsl,imx25-tcq".
8 - reg: Memory range of the device.
9 - interrupts: Should be the interrupt number associated with this module within
11 - fsl,wires: Should be '<4>' or '<5>'
14 - fsl,pen-debounce-ns: Pen debounce time in nanoseconds.
15 - fsl,pen-threshold: Pen-down threshold for the touchscreen. This is a value
20 - fsl,settling-time-ns: Settling time in nanoseconds. The settling time is before
25 The first queue is for the touchscreen, the second for general purpose ADC.
