Follow the example of the recently added apq8016-sbc-usb-host.dtso and convert apq8016-sbc-d3-camera-mezzanine.dts to a DT overlay that can be applied on top of the apq8016-sbc.dtb. This makes it more clear that this is not a special type of DB410c but just an addon board that can be added on top. Functionally there should not be any difference since apq8016-sbc-d3-camera-mezzanine.dtb is still generated as before (but now by applying the overlay on top of apq8016-sbc.dtb). Since dtc does not know that there are default #address/size-cells in msm8916.dtsi, repeat those in the overlay to avoid dtc warnings because it expects the wrong amount of address/size-cells. It would be nice to have a generic overlay for the D3 camera mezzanine (that can be applied to all 96Boards) but that's much more complicated than providing a board-specific DT overlay as intermediate step. Cc: Bryan O'Donoghue <bryan.odonoghue@linaro.org> Signed-off-by: Stephan Gerhold <stephan@gerhold.net> --- NOTE: I haven't tried booting this (since I don't have the camera mezzanine) but I compared the resulting apq8016-sbc-d3-camera-mezzanine.dtb which seems to be equivalent to the old one (aside from phandle numbering and ordering). It wouldn't hurt if someone could try booting this to be sure. :-) --- arch/arm64/boot/dts/qcom/Makefile | 5 +++-- ...ra-mezzanine.dts => apq8016-sbc-d3-camera-mezzanine.dtso} | 12 ++++++++++-- 2 files changed, 13 insertions(+), 4 deletions(-)
