Hi all. I have some problems when I try to use the touchscreen driver
edt-ft5x06 with a device tree overlay on my beaglebone black.
I work with the 3.8.13 kernel and a Debian distribution. This is the device
tree overlay I am using:
/dts-v1/;
/plugin/;
/ {
compatible = "ti,beaglebone", "ti,beaglebone-black";
part-number = "BB-BONE-TOUCH";
version = "00A0";
exclusive-use =
/* the pin header uses */
"P9.17", /* i2c1_scl */
"P9.18", /* i2c1_sda */
"P9.21", /*wake up from host am33 to slave ft5x"
"P9.25", /*interrupt, def state mcasp0_ahclkx ,
change to input pin gpio3_21*/
/* the hardware ip uses */
"i2c1";
fragment@0 {
target = <&am33xx_pinmux>;
__overlay__
{
bb_i2c1_pins: pinmux_bb_i2c1_pins
{
pinctrl-single,pins = <
0x15c 0x74 /* i2c1_scl */
0x158 0x74 /* i2c1_sda*/
>;
} ;
edt_ft5x06_pins: pinmux_edt_ft5x06_pins
{
pinctrl-single,pins = <
0x08C 0x37 /* pin interrupt P8.18 (GPIO2_1) mode7 as
gpio, enable input, enable input pullup*/
0x044 0x17 /* wake up pin control to slave from
host: pullup,mode7 p9.23,gpio1_17 */
>;
};
};
};
fragment@1 {
target = <&i2c1>; /* i2c1 is numbered correctly */
__overlay__
{
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&bb_i2c1_pins>;
clock-frequency = <400000>;
#address-cells = <1>;
#size-cells = <0>;
edt-ft5x06@38
{
status = "okay";
compatible = "edt,edt-ft5x06","edt,edt-ft5206";
pinctrl-names="default";
pinctrl-0=<&edt_ft5x06_pins>;
reg = <0x38>;
interrupt-parent = <&gpio2>;
interrupts = <1 1>;
wake-gpios = <&gpio1 17 0>; //3rd para:0 - active
hig, 1-active low
reset-gpios = <&gpio1 17 1>;
touchscreen-size-x = <800>;
touchscreen-size-y = <480>;
};
};
};
};
When I load it into the capemanager I get the following error:
[ 11.024611] edt_ft5x06 1-0038: no platform data?
I'm quite lost here. Can anyone help?
Thank you
