Sorry, that was my fault, I used all caps in the commit message. In the tree
the boards are lowercase, grepping on next-20260825:

Through this series we add support for these on Texas Instruments 
j784s4-evm, j722s-evm,
j721e-evm, j721s2-evm and etc.(All these are supported upstream). For 
simplicity I just
used the two latest upstreamed platforms i.e j784s4-evm and j722s-evm in 
the commit message.

I will also include the target company details in the commit message, 
something like below:

"Texas Instruments DS90UB960 deserializer and DS90UB953 serializer 
facilite capturing
through multiple camera sensors on various Texas Instruments platforms. 
Some of the
supported platforms in upstream where these deserializer and serializer 
can be used
are Texas instruments j784s4-evm, j722s-evm, etc.

Hence enable building Texas Instruments DS90UB960 deserializer and
DS90UB953 serializer drivers as modules."

Thanks and Regards,
