Hi, Gregor.
Just wrote some my test module-stub, mix of acpi and just direct i2cdev
creation on i2c-4 0x48, anyway it is even possible just used echo icn8528
0x48 > /sys/bus/i2c/devices/i2c-4/newdevice
instead it.
The main question is - wakeup chip, and gpios pins.
Actually, the procedure of h
Hi Gregor,
Thank you for reply!
As I mentioned in linux-input@How to use ACPI for touchscreen - the acpi
provided info looks like total false.
For the begining I am trying to achieve mimimal - detect chip and just wake
up it.
Actually have tried - modified your driver for gsl1680 and also icn83

Sorry, I was mistaken. chipone_icn8318 tries to fetch the information from
DeviceTree. No sysfs inter

I think many TS controllers use the same or a similar sequence to this:
- Set wakeup pin low
- Wait for a few ms
- Set wakup pin high
How long is probably chip dependant.

Hi All :) that still keep silence!
I would like to mention the following :
In linux-sunxi there is
http://dl.linux-sunxi.org/SDK/A80/A80_SDK_20140728_stripped/lichee/linux-3.4/drivers/input/touchscreen/icn83xx/
it is strange that the author is from Chipone, as minimum should be someone
who adop
Coud someone be so kind to describe how to initialize this chip?
I guess it has INT/WAKE gpio pin? Am I right?
How to find out having working touch in Android and Windows it ? There is
no at the moment driver in Linux for this touch, so I have not "right point
of start" for finding out gpio pin.
