[Ltib] EA3250: Touchscreen not functional with 2.6.34 kernel

[Burghardt Arne]

Hi Kevin,

i have attached a scope to the SPI signals of the TSC2046 touchscreen controller and got some interesting results:

1) CS, CLK & MOSI signals are ok
2) MISO has a low level of ~2.0 V ! High level is ~3.1V

That smells, if there are some output drivers connected...
Could you please check, if the signal SPI1_DATIN (GPI_25) is configured as an input ? I have already searched for the init procedure, where all GPIOs or SPI related registers are initialized, but without success.

Thanks for your help !

Best regards

  Arne
