[PATCH 00/49] DRM driver for Hikey 970

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).

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.

This are all no longer used and can all be dropped.
See what other drivers do - so things can be simplified.

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