I have a working version now, but... Due to the scale of the needed changes we would need different compatib= le string for the single hwmod version. The Linux driver itself works fine if I don't change the compatible (ti,edma3). Boots fine with the old and new DTS file, but the edma sect= ions are not compatible anymore IMO. I don't want to rush in a new binding for it since I want to make sure = that the new binding will be usable when I got the chance to rewrite the edm= a stack (get rid of the code from arch/arm/common/edma.c) We have the xbar support embedded in the current edma driver - not the = same crossbar as we have in dra7, it is a bit more problematic (very problem= atic). Currently we do not have support for more than one TPCC via DT, legacy = boot on SoC with more than one TPCC is also going to be interesting. Since we will need new bindings for the edma when we fix the multiple h= wmods I think we should allow us some time to think about it a bit and come up = with something which will work in the future and it is nice to look at it at= the same time ;) And I will be away for one week... If you want I can send an RFC/DO NOT MERGE series with the code I have tomorrow in case you want to see it, but I think it will look quite a b= it different at the end. --=20 P=E9ter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
