Okay, I will update the device compatibles to something like this..
DRA742
compatible = "ti,dra742", "ti,dra74", "ti,dra7"
DRA722
compatible = "ti,dra722", "ti,dra72", "ti,dra7"
And the evm compatibles as
DRA742 EVM: Software Developement Board for DRA742
compatible = "ti,dra7-evm", "ti,dra742", "ti,dra74", "ti,dra7"
DRA722 EVM: Software Development Board for DRA722
compatible = "ti,dra72-evm", "ti,dra722", "ti,dra72", "ti,dra7"
I was also calling the .dtsi files as dra72x.dtsi and dra74x.dtsi, do you suggest I call
them dra742.dtsi and dra722.dtsi instead? Just that if we end up with a dra745 which is
fully compatible with dra742, as you mentioned above, we would be using a dra742.dtsi for a dra745
device which could be a little confusing.
