Lcd touch sensitivity issue| goodix

[adarsh1997]

Hi
I am using  lcd with imx6dl custom board .I want to change the sensitivity level of lcd.
Lcd is connected to i2c. I am using gt911 lcd driver.

I have tried by changing 0x8053 reg(screen touch level)  values from driver(goodix.c) . 
By reading the value of 0x8053 reg from driver, i got 0x64 by default .now i am trying to change this value but after changing the values touch is not working.

Can anyone help me on this .which registers values i can configure to change the sensitivity of lcd. 
or what should be the range of  this 0x8053 reg(screen touch level).

Hi
Issue solved.
GT911 supports Register Value Modification. When modifying any register in the configuration area (0x8047
-0x80FE) based on the timing sequence as specified in section 2, it is required to update Config_Chksum (0x80FF)
and eventually set Config_Fresh (0x8100) to 1. Otherwise, the modification is invalid; when modifying any
registers outside configuration area, it is unnecessary to modify Config_Chksum and Config_Fresh.
