documentation.

-sun4i resistive touchscreen controller
---------------------------------------
-
-Required properties:
- - compatible: "allwinner,sun4i-a10-ts", "allwinner,sun5i-a13-ts" or
-   "allwinner,sun6i-a31-ts"
- - reg: mmio address range of the chip
- - interrupts: interrupt to which the chip is connected
- - #thermal-sensor-cells: shall be 0
-
-Optional properties:
- - allwinner,ts-attached        : boolean indicating that an actual touchscreen
-                                  is attached to the controller
- - allwinner,tp-sensitive-adjust : integer (4 bits)
-                                  adjust sensitivity of pen down detection
-                                  between 0 (least sensitive) and 15
-                                  (defaults to 15)
- - allwinner,filter-type        : integer (2 bits)
-                                  select median and averaging filter
-                                  samples used for median / averaging filter
-                                  0: 4/2
-                                  1: 5/3
-                                  2: 8/4
-                                  3: 16/8
-                                  (defaults to 1)
-
-Example:
-
-       rtp: rtp@01c25000 {
-               compatible = "allwinner,sun4i-a10-ts";
-               reg = <0x01c25000 0x100>;
-               interrupts = <29>;
-               allwinner,ts-attached;
-               #thermal-sensor-cells = <0>;
-               /* sensitive/noisy touch panel */
-               allwinner,tp-sensitive-adjust = <0>;
-               allwinner,filter-type = <3>;
-       };
