Hi TI:
We ported our TSC2007 driver referring to https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/input/touchscreen/tsc2007_core.c#n391.
When we tried to test device under certain temperature(-15C), we got returned failure at line 391 as below message shown and the device lost touch function:
<3>[ 1.270065] tsc2007 4-0049: i2c io error: -110
<3>[ 1.270072] tsc2007 4-0049: Failed to setup chip: -110
<4>[ 1.270157] tsc2007: probe of 4-0049 failed with error -110
The returned value is not always -110. Sometimes it is -107 or -2. We saw these error message when trying test devices in other different termperature(like -30C).
May I ask what it mean to TSC2007 when we got each of these returned numbers?
And any suggestion to improve this probe issue?
Thank you in advance.
