+* Broadcom's IPROC Touchscreen Controller
+
+Required properties:
+- compatible: must be "brcm,iproc-touchscreen"
+- reg: physical base address of the controller and length of memory mapped
+  region.
+- clocks:  The clock provided by the SOC to driver the tsc
+- clock-name:  name for the clock
+- interrupts: The touchscreen controller's interrupt
+
+Optional properties:
+- scanning_period: Time between scans. Each step is 1024 us.  Valid 1-256.
+- debounce_timeout: Each step is 512 us.  Valid 0-255
+- settling_timeout: The settling duration (in ms) is the amount of time
+                    the tsc waits to allow the voltage to settle after
+                    turning on the drivers in detection mode.
+                    Valid values: 0-11

+                   11 = 10.24 ms
+- touch_timeout: The continuous number of scan periods in which touch is
+                not detected before the controller returns to idle state.
+                Valid values 0-255.
+- average_data: Number of data samples which are averaged before a final
+                data point is placed into the FIFO
+                Valid values 0-7
+                0 =   1 sample

+                6 =  64 samples
+                7 = 128 samples
+- fifo_threshold: Interrupt is generated whenever the number of fifo
+                entries exceeds this value
+                Valid values 0-31
+- touchscreen-size-x: horizontal resolution of touchscreen (in pixels)
+- touchscreen-size-y: vertical resolution of touchscreen (in pixels)
+- touchscreen-fuzz-x: horizontal noise value of the absolute input
+                      device (in pixels)
