I am using gt928 touch conroller on TI am625 based custom board.

Touch was not responding and at boot up we are getting goodix_928_cfg.bin failed with error -2

dmesg | grep -i good

[ 1.343111] Goodix-TS 2-005d: supply
AVDD28 not found, using dummy regulator

[ 1.343303] Goodix-TS 2-005d: supply VDDIO
not found, using dummy regulator

[ 1.465252] Goodix-TS 2-005d: ID 928,
version: 1040

[ 1.466312] Goodix-TS 2-005d: Direct firmware load for goodix_928_cfg.bin failed with error -2

[ 1.470893] input: Goodix Capacitive
TouchScreen as /devices/platform/bus@f0000/20010000.i2c/i2c-2/2-005d/input/input0

[ 1.471105] evbug: Connected device:
input0 (Goodix Capacitive TouchScreen at input/ts)

Is this driver config need to be enabled in dts? How to generate goodix_928_cfg.bin for gt928 driver
in linux?
