[PATCH v2 1/6] drm/exynos: add Exynos5433 decon driver

Hi,
Some feedback comments - most of these are not unique to your 5433
DECON driver but endemic throughout Exynos, so I don't blame you for
them - but they should be fixed anyway.

Do you really not even need to set a control register?

This seems much more likely to be DPMS, no?

As does this.

Have you tested DPMS on/off, without enabling/disabling the CRTC
first? Does it work?

It would be nice to have a #define for the largest-supported window number.

Please remove the 'default' case. If you get here with a format you
don't know how to configure, then it is a bug and should be fixed: the
plane should never advertise a format that it cannot support.

Replace plane->fb_width * bytes_per_pixel by plane->fb_pitch please,
and set plane->fb_pitch from exynos_drm_plane->pitch. See this patch:
https://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg42861.html

You should be able to test this case, either by making a specialised
userspace program which has a larger pitch with garbage values in the
padding (see https://msdn.microsoft.com/en-us/library/windows/desktop/aa473780(v=vs.85).aspx),
or by testing a resolution where width*bytespp is not a multiple of 4,
e.g. 1366x768.

Again, replace fb_width*bytes_per_pixel with fb_pitch.

val_h = plane->fb_pitch - (plane->crtc_width * bytes_per_pixel);

Should failing to register the CRTC also decrement priv->pipe?

As above, it seems like DPMS will not do enough here.

If decon->drm_dev is ever NULL, it sounds like something has gone very
seriously wrong.

Ditto - when would drm_dev be NULL?

Yes, my impression was that DECON supported both internal and
external, i.e. would replace both FIMD/Mixer. This patch only supports
the internal interface: are you planning to add support for the
external/TV/HDMI interface as well? If so, how does this work with the
DT format you have defined? Should there maybe separate decon-int and
decon-tv subnodes, each of which create one CRTC? The Android tree
seems to rely on static configuration, but presumably we would need a
much more nuanced approach.

If so, it seems like the first start would be to add a basic DECON
binding which covered the entire controller, and then as a next step
add support for decon-int as a subdevice of this.

Cheers,
Daniel
