Hi Mauro.

Will have a look, patches are no named "dt-bindings" so I did not see
them in first round.

Thanks.
Here follows a scattered amount of small comments embeeded in the code
below.

Also a few high level comments:

There is too much unused code present - please delete.
I dod not think I spotted it all.

Some style issues - ask checkpatch --strict for help identifying
these.

Needs to be adapted to new bridge handling - see comments.
Move panel stuff to drm_panel (or maybe I got confsed so this was just
bride stuff).

Lots track a few times - so may have confused myself a few times.

Many small comments - but general impression is good.

Happy hacking!

Sam

Implied by DRM_HISI_KIRIN9XX, so not needed.

This is essential a copy of DRM_HISI_KIRIN9XX - so no need for this
extra Kconfig variable.

Can we drop the license text when we have SPDX?
Same goes for other files if they mix it.

Spaces after "/*" and before "*/". Applies for many comments.

Use of drm_device.dev_private is deprecated.
Use subclassing and upcasting.

See gpu/drm/drm_drv.c for a small example how to do it
(look for a big comment with code).

drmm_mode_config_init() or something like that.

In general look for the drmm_* variants to use in the init functions.
There should be no need to deallocate in errro cases.

This can use one of the helpers - see how other drivers
uses a macro that define all the common helper functions,
so they end up with a very slimm definition here.

Note - could be much worse, you just need to catch up on recent
improvements.

There is better ways to do this. See drm_drv.c for the code example.

Pass 0 and use mode_config.preferred_depth.

Drop this as dev_private should not be referenced anywhere.

This indirections is not needed - or at least almost not needed.
cleanup, suspend, resume are always the same - so call them direct.
Consider a better way to hande the init function the only difference is
the FB_ACCEL_KIRIN970 value.

See what other drivers do - so things can be simplified.

The bridge should be attached with the falg that tell the bridge NOT to

The display driver shall created the connector.

Please see how other drivers do this (but most driver uses the old
pattern so so look for drm_bridge_attach() with the flag argument.
