This was meant to illustrate that even though core layouts often look similar we should not try to connect different product board files unnecessarily, as the small differences will make everything more complicated. The "reload" definitly is a completely different product that only shares the manufacturer (firefly) and the soc (rk3288) with the other product and as I wrote should get its own independent dts file. If anything you could do a split into a reload-core dtsi for the system-on- module part and a baseboard dts that includes that (something like what is done for rk3288-rock2). > > Also, when adding a new board, please also add an entry to > > Documentation/devicetree/bindingd/arm/rockchip.txt > > I would send a patch set in a few days. > > > Thanks > > Heiko > > Thank you for you review and you patient again no problem, always nice to have more people play with Rockchip stuff on a mainline kernel :-) Heiko -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
