I used graph-card and could get few things working with it. Based on the 
feedback so far, I am planning to split the series as suggested and send 
two series as below.
[1] Tegra AHUB series and related DT bindings as V5.
[2] Audio graph card enhancements and related DT bindings for Tegra 
platforms as V1.

Thanks,
Sameer.
