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>;
};
