Great Piotr, can you share a patch with the needed modifications? Thanks.

No, Piotr, haven't found a dual core tablet with out of the box support for the touchscreen. Regards.

Re: [linux-sunxi] Re: Kurio 7S and boot linux (Debian...) sdcard... how??
Hello Piotr, I see this tablet has a Focaltech touchscreen IC, and it's supported in the kernel 3.4, have you successfully loaded the driver for it? Thanks.

Re: [linux-sunxi] Tablets with supported touchscreen IC
Thanks John, it's a good start, I think it would also be useful to have first hand reports from current users of devices not listed there, or IC related info, any help will be appreciated. Thanks again.

[linux-sunxi] Tablets with supported touchscreen IC
Hello All, I've working in a project using allwinner based tablets, but the problematic point has been to get the touchscreen drivers loading and working, and the lack of documentation about which touchscreen IC they include. I'd like to know if you have any recomendation of a tablet brand and model with a dual core or greater allwinner soc, and a touchscreen driver not requiring any firmware extraction from the android kernel, or any additional device specific steps, compiling the kernel driver and some simple configuration is ok. Many thanks in advance. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.

Re: [linux-sunxi] Re: gslx680 driver ported to sunxi
Thanks Joe, I've set that ctp_firmware parameter with relative and complete path, but the kernel doesn't seem to be able to find it. I was told to use /lib/firmware, and it fails with the same error, and the kernel I'm using (3.4.79+), hasn't a very detailed debugging of where it is searching. Is there a more bullet proof good way to load the firmware?, or, how can I debug where the kernel is trying to load the firmware from? Many thanks in advance!

[linux-sunxi] Re: gslx680 driver ported to sunxi
I have compiled the gslx680 driver, but there is a problem finding the firmware file (Error -2). Is there an standard location where the module will search for it?
