hi:
we use tsc2013-q1 on the mcu amlogic m805 to use the touchscreen.
In the driver probe,i configure follow
CFG[62] = 0xa58c
CFG[6a] = 0x0
CFG[72] = 0xb81c
and when touch ,i set the control byte this mode
regmap_raw_write(tsc2013->regmap,0x84,&err,0);
when the os boot,i touch the touchscreen,i read the x1,x2,y1,y2,z1,z2,ix,iy by this function
regmap_read(tsc2013->regmap,0x01,&x1);
regmap_read(tsc2013->regmap,0x09,&x2);
regmap_read(tsc2013->regmap,0x11,&y1);
regmap_read(tsc2013->regmap,0x19,&y2);
regmap_read(tsc2013->regmap,0x21,&ix);
regmap_read(tsc2013->regmap,0x29,&iy);
regmap_read(tsc2013->regmap,0x31,&z1);
regmap_read(tsc2013->regmap,0x39,&z2);
i touch the five point,and debug the value
central point

the x,y value is wrong,not get the true value.
How can I modify to work correctly?
PS:the touch screen work good when it work with am335x.
