CCing Jingoo,
Is that ok to remove eDP driver from video/exynos? Isn't this driver really
used by Linux framebuffer driver, s3c-fb.c?

Yes, it is used by s3c-fb.c.
Of course, now s3c-fb driver is dead code because this driver doesn't
support device tree yet but we would need more reviews and discussions about
moving this driver into drm side. Let's watch new rules for device tree
bindings of DRM world. So I'd not like to merge this driver yet.
's3c-fb' driver is still used for other mass products projects.
Just, device tree support patch is not yet submitted.
Sean Paul,
When moving the driver, notify related Maintainers of that driver.
Please use 'scripts/get_maintainer.pl' next time.
Best regards,

Current in-tree users of s3c-fb drivers are s3c2443, non-DT s3c64xx and
all s5p* SoCs. It is not used on Exynos SoCs anymore.
As for Exynos DP driver, what SoCs does it support? If only Exynos (as the
name suggests) then there is no point in keeping it at video/exynos and
making it a part of Exynos DRM driver seems reasonable to me.
Best regards,
Tomasz

Hi Tomasz Figa,
Some mass product projects using Exynos5250 and etc, use s3c-fb driver
and dp driver. Also, these projects are still using Framebuffer, not DRM.
As for Exynos DP driver, what SoCs does it support? If only Exynos (as the
name suggests) then there is no point in keeping it at video/exynos and
making it a part of Exynos DRM driver seems reasonable to me.
However, when considering only mainline kernel, I have no strong objection.
As you know, many Linux kernel based OS projects using Exynos, are using
DRM, not Framebuffer.
Also, if moving DP driver to DRM, MAINTAINERS entry for Exynos DP driver
should be updated, too.
Best regards,
Jingoo Han

Well, those are based on vendor trees anyway, so do not really affect
mainline kernel.

Generally, fbdev is strongly discouraged in any new systems and DRM is the

back to Exynos platforms.
Also, if moving DP driver to DRM, MAINTAINERS entry for Exynos DP driver
should be updated, too.

Yes, you're right.
Personally, I think that all Exynos platforms should go into DRM, not FB.
One more thing, then how about moving Exynos MIPI to DRM side?
Is there any plan on Exynos MIPI?

Well, it will eventually have to be moved somewhere else than it is, but I
believe this will have to wait for Common Display Framework.
This is because the case of MIPI DSI is slightly different from
DisplayPort, since it is not an enumerable/auto-configurable interface and
requires dedicated panel drivers and static data provided by board
designers (in DT for example). Handling of such things in a generic way
will be done by CDF.
