[PATCH v7 4/7] media: venus: hfi_plat_v4: Add capabilities for the 4XX lite core
Posted by Jorge Ramirez-Ortiz 2 months, 3 weeks ago 
Populate the HFI v4 lite capability set used by the AR50_LITE video
core.

These capabilities define the supported codec formats and operational
limits specific to this streamlined VPU variant.

Ok, now the WARN_ON() makes more sense, its a progressive.

I don't much like setting hard-coded values in functions.

It must be possible to pass these as parameters. We have all of these 
enumeration structures - it seems a shame to move some specific 
enumerations to hard-coding.

Please consider if there is a way to bury this into one of the 
enumeration params.

I'm not a big fan anymore of ternary nor of declaring multiple things on 
one line.

And I'll preempt Konrad, reverse Christmas tree in the declaration where 
possible for preference.

I suppose the hard-coded *val = 5 || *val = 8; isn't important but it 
would be _nice_ to not hard-code, up to you how much you want to 
implement for the next version.

This code all looks reasonably correct/consistent with antecedents.
