Re: [PATCH v4 5/7] drm/etnaviv: add HWDB entry for VIPNano-QI.7120.0055

[Lucas Stach]

Hi Tomeu,

the changes itself look good to me now, I was just very confused about
the ordering of the patches.

I would have expected them to be in this order:
1. Add NN cores to chip identities struct (set to 0 for all existing
entries in HWDB)
2. Add UAPI warning
3. Add HWDB entry for VIPNano-QI.7120.0055 (having NN cores set to
correct value, so you don't touch the entry twice in the same series)

Regards,
Lucas
