Hello!

I have a Ployer Momo 12 tablet with the touchscreen from U30GTH (101028-01A-V1). With the stock ployer kernel (http://crewrktablets.arctablet.com/?wpfb_dl=1198) I have working only left half of touchscreen rotated counterclockwise. With this stock U30GTH kernel or HB U30GT kernel touch works pretty fine, but no sound and autorotate. Is it possible to port ft5x0x_ts module to original ployer kernel?

dmesg with stock ployer kernel:

Hello, All!

Is there a way to swap touchscreen axis without  driver  recompiling, e.g. as on Allwinner's tablets through script.bin changing.

This is not a problem of the driver. The strange kernel flashed its touch controller firmware into your chip. The Momo stock kernel does this obviously not. So this is a dead end.

Hello!

This is not a trouble with wrong TS firmware - my touchscreen works fine with strange kernel and with stock kernel, but with stock kernel axis are swaped (incorrect viewport rotation).
