This binding is not much validating the old DSI v2.

Currently we don't differentiate old v2 from new versions,
so we need to figure out how to validate them.

I propose specific compatible depending on mdss version, but I would be
glad, if someone with deeper knowledge proposed the names.

I'm willing to implement it then and back from autodetection.

I'd suggest to use hardware-specific compatible for apq8064 (and maybe
other v2 hosts if somebody adds support). For example
"qcom,apq8064-dsi-ctrl" or "qcom,dsi-ctrl-apq8064" (no strong
preference here).

The former.

For 6G hosts it will probably make sense to use IP versions instead
("qcom-dsi-ctrl-6g-v2.4.1").

Humm, we went down the path of version numbers for QCom blocks, but the 
result was not much reuse of same version on more than 2-3 parts if 
that. So stick with SoCs for naming unless there's a strong case that 
version numbers to SoC parts is 1 to many.
