I am working on porting BSP for IMX7 solo based custom board. When I looked in the DTS files, I can only see files related to IMX7 dual. For instance, all the name of dts files available for IMX7 starts with "imx7d_*.dts". Can you please say, where can I get the dts files for IMX7 solo? What are all the changes (in terms of building the source code and booting ) needed for IMX7 Solo?
