Hi Sean,

I do not think there is a more current driver available for that device, so you might need to port the code over yourself. We are checking with our software team to confirm and will get back to you within 48 hours.

Hi Sean

Kindly share the link where the driver for Linux 2.6 is? I'll check this code.

And which kernel version your project will use? Looking forward to your reply. Thanks.

Hi Shenghao

Thank you very much for your help.

I find two TSC2046 Linux driver in e2e.

1.

2. 

tsc2046 driver.docx

I see e2e said TSC2046 can use same Linux driver with ADS7846.

I also find a ADS7846 driver from e2e and let customer try to use.

3. 

https://github.com/torvalds/linux/blob/master/drivers/input/touchscreen/ads7846.c

So I totally have 3 Linux driver as up.

Customer's kernel version is 5.4.70. They said Linux 3.0(4.0 is better) or above is OK.

And do you have device-tree for TSC2046? Below is device-tree I found for customer for another device tlv320, please refer to it.

git.kernel.org/.../tlv320aic31xx.h

Thanks very much.

Hi Shenghao,

Many thanks to you.

With your help my customer have no problem with driver.

They want to know do you have device tree for TSC2046 or ADS7846(I don't know can TSC2046 use ADS7846's device tree)?

I try to find it in the whole e2e, and I failed to find.

Could you please help on it?

Thanks very much.

Best Regards,

Sean Song
