Hi,I use TPS65070X as Touchscreen Interface,which use Kernel support driver drivers/input/touchscreen/tps6507x-ts.c and drivers/mfd/tps6507x.c ,
when i use AC adapter to povide power to my board,tps65070 touchscreen driver register succefully,but when i use Battery to pvovide,it faild,
tps6507x-ts: probe of tps6507x-ts failed with error -5
s3c-i2c s3c-i2c.0: i2c-0: S3C I2C adapter
my hw staff check tps65070 PMIC power,it is right,so whats the issue? or can give me some advice to ensure hw is OK ?
When use AC adapter to provide Power to board,tps65070 touchscreen driver work find roughly,but some time,my arm11 i2C driver also say -110 error in stop condition.
