[PATCH 0/3] DC pull request cleanup

[PATCH 0/3] DC pull request cleanup

[Harry Wentland]

Patches to make DC use kzalloc/krealloc/kfree directly.

Also updating the TODO list after a closer look at I2C in DC.

Harry Wentland (3):
  drm/amd/display: Use kernel alloc/free
  drm/amd/display: Remove alloc/free macros
  drm/amd/display: DC I2C review

[PATCH 2/3] drm/amd/display: Remove alloc/free macros

[Harry Wentland]

Now that we don't abstract kernel alloc interfaces we don't need
those anymore.

[PATCH 3/3] drm/amd/display: DC I2C review

[Harry Wentland]

While reviewing I2C in DC identified a few places. Added a couple to the
TODO list.

1) Connector info read

See get_ext_display_connection_info

On some boards the connector information has to be read through a
special I2C channel. This line is only used for this purpose and only on
driver init.

2) SCDC stuff

This should all be reworked to go through DRM's SCDC code. When this is
done some unnecessary I2C code can be retired as well.

3) Max TMDS clock read

See dal_ddc_service_i2c_query_dp_dual_mode_adaptor

This should happen in DRM as well. I haven't checked if there's
currently functionality in DRM. If not we can propose something.

4) HDMI retimer programming

Some boards have an HDMI retimer that we need to program to pass PHY
compliance.

1 & 3 might be a good exercise if someone is looking for things to do.

Best case I think would be if you directly implement the i2c_adapter
in there. It's a tiny abstraction/api, so should be trivial to
reimplement for the windows side. Or at least align really closely.
Even more so for the gpio bit-banging case, that should use the linux
implementation I think. Might be good to clarify.

Anyway, ack on this.

We already have dual_mode helpers. It's one of the todo's I've added,
merged this with point 15?

I thought it eventually goes through the i2c stuff, after a few layers
at least. Maybe I got derailed. Anyway, makes sense.

With 20 merged into 15, ack on the patch from me.
