Universal cape seems always to be loaded
Even changing uboot_base_dtb and uboot_base_dtb_univ to am335x-bonegreen-wireless.dtb does not make any difference.
/sys/class/backlight does not show up
DTBO becomes unloadable when enabling the lcd part
Expected behavior
PWM backlight should be available.
I'm fairly new to the whole device tree business, so probably I made some mistakes in my DTS.
Where can I find information about exclusive-use? Is it BeagleBone specific? Some overlays make use of it, others disable the pinmux nodes (like I did for now).
Is <&ehrpwm1 1 x> the right way to address ehrpwm1B? Where can I find this kind of information?

errors are exactly the same without overlay. System config is unchanged except for additional BR packages.Changes in
