这个驱动文件还要打点补丁才行:

goodix_configure_dev(ts);可是我的芯片是 GT9147, 这可怎么办呢?
不管了, 先照葫芦画瓢吧.

终于找到一个固件: goodix_9147_cfg.zip
拷贝到 /lib/firmware/goodix_9147_cfg.bin
可以注册成功:
# modprobe goodix
[ 39.985469] Goodix-TS 0-005d: ID 9147, version: 1040
[ 40.058363] input: Goodix Capacitive TouchScreen as /devices/platform/soc/1c27000.i2c/i2c-0/0-005d/input/input1但是evtest 纹丝不动.
dts这样设置:
gt9115d: touchscreen@5d {
compatible = "goodix,gt911";
reg = <0x5d>;
interrupt-parent = <&pio>;
interrupts = <4 3 IRQ_TYPE_EDGE_FALLING>; /* (PE3) */
pinctrl-names = "default";
/*pinctrl-0 = <&ts_reset_pin>;*/
irq-gpios = <&pio 4 3 GPIO_ACTIVE_HIGH>; /* (PE3) */
reset-gpios = <&pio 4 4 GPIO_ACTIVE_HIGH>; /* RST (PE4) */
touchscreen-swapped-x-y;
};https://github.com/torvalds/linux/blob/master/drivers/input/touchscreen/goodix.c
GOODIX_CONFIG_911_LENGTH 取值是 186, 我那个 goodix_9147_cfg.bin 也刚好186字节。
按理来说应该可以用才对。
