[Testers wanted: sunxi Device Tree overlays]

- device tree compiler (dtc) should be recent enough - either compile from here or use one from kernel headers

- you need to tell dtc that you are compiling an overlay (add -@ command line parameter)

The missing '-@' wasn't the issue, as I tried with and without. With the dtc from my linux-git clone it worked.

Didn't expect my Debian (testing) version of dtc being the issue here - thanks for pointing me there!

For reference, that's the version which caused me above stated trouble:

Hey,

 

I don't even manage to compile the DTS files.

For example: https://github.com/armbian/sunxi-DT-overlays/blob/master/examples/spi-ads7846.dts

 

$ dtc -I dts -O dtb -o foo.dtbo foo.dts
foo.dtbo: Warning (unit_address_vs_reg): Node /fragment@0 has a unit name, but no reg property
foo.dtbo: Warning (unit_address_vs_reg): Node /fragment@1 has a unit name, but no reg property
foo.dtbo: Warning (gpios_property): Property 'pendown-gpio', cell 2 is not a phandle reference in /fragment@1/__overlay__/ads7846@0
foo.dtbo: Warning (gpios_property): Could not get phandle node for /fragment@1/__overlay__/ads7846@0:pendown-gpio(cell 2)
dtc: livetree.c:521: get_node_by_phandle: Assertion `(phandle != 0) && (phandle != -1)' failed.
Aborted

The warnings don't even seem to be the issue - suppressing (-q) them and forcing compilation even with errors (-f) still results in the assert. Any hint?
