  1. Yeh that looks like the right flag which seems to be missing from the defconfig file for the neo. I will build the kernel tomorrow and if successful will open a 1 line PR. Thanks
  2. Legacy is missing the spi display driver which I need.
  3. Need uinput module to use with tslib but "nanopineo 4.11.0-sun8i" doesn't seem to have it, neither static linked to the kernel or as a dynamic module. What am I missing? Thank you
  4. Well this is strange and doesn't seem like the intended behavior. With the compatible property set to "ti,ads7843" I have to modprobe the module since it doesn't load automagicaly like when using "ti,ads7846". Strange thing is that at the time I modprobe it picks up the DT model setting: [ 8.209860] ads7846 spi0.1: ads7843 spi0.1 2000kHz 8 bits mode=0x00 Well at least it is working now
  5. Thank you, Yeh I saw that doc file, and been playing with a few properties. I tried changing the compatible property before and if set to ads7843 which according to the DT doc is a valid one I get no /dev/input/eventX created although dmesg shows the ads7846 driver grabing spi0.1.
  6. Hi all, I have been playing with a NanoPi Neo and the 2.8" screen with toutchscreen also from friendly Arm on Linux nanopineo 4.11.0-sun8i. Making it work was not very easy since it was the first time I messed with device trees, also add to rewire the screen to use a different pin for the touchscreen chip select since the connector is a column bigger that the neo's. I can provide more information or the dts file if it is of interest to someone. TL:DR: The problem is that the toutchscreen accuracy is not so great especially on the top part of the screen. I see that the ads7846 driver which I'm using has a "model" option which by being set to "ads7843" handles stuff a bit different. But how the I pass the model to the driver? "model" has no device tree binding, should I use modprobe? Can someone explain the interaction between device trees and modprobe? Thanks
