Hello,
I'm currently trying to get the sun4i-ts working for the allwinner f1c200s. I already checked the registers are the same and I have adjusted the offset in the device tree. I added debug output to the driver to see, where it gets stuck.
The result is that "thermal = devm_thermal_zone_of_sensor_register(ts->dev, 0, ts, &sun4i_ts_tz_ops);" is returning "-EPROBE_DEFER"..
It is probably an configuration error on my side, the device tree will be attached at the end. I would be glad if someone could help me.
Thanks,
Thomas
