[PATCH v2 0/6] Support for Exynos7870's display stack (DECON, MIPIPHY, DSIM, etc.)

[PATCH v2 0/6] Support for Exynos7870's display stack (DECON, MIPIPHY, DSIM, etc.)

[Kaustabh Chakraborty]

Exynos7870 has a IP subsystem in its architecture dedicated to display
management. Notably, this block includes the Display Enhancement
Controller (DECON), and the DSI Master (DSIM).

The following series and its sub-series implement all components for a
functioning display pipeline. All vital information which helped shaping
up the patches have been retrieved from Exynos7870 vendor kernel sources
as provided by Samsung.

Testing has been done on all three devices available upstream, i.e.
Samsung Galaxy J7 Prime (samsung-on7xelte), Samsung Galaxy A2 Core
(samsung-a2corelte), and Samsung Galaxy J6 (samsung-j6lte). Regrettably,
I've only been able to test the functionality on video mode, as none of
the devices have panels working in command mode.

This series implements changes in the SoC subsystem, which includes
devicetree additions. It depends on all sub-series listed below:

Changes in v2:
- modified compatible hierarchy to use non-deprecated syntax (krzk)
- fixed subject prefixes of [v1 2/5], [v1 3/5], [v1 4/5], [v1 5/5] (krzk)
- removed simplefb nodes instead of disabling it (krzk)
- added dt-bindings patch to allow mipi-phy node under PMU
- changed clock names of dsim node
- Link to v1: https://lore.kernel.org/r/20250612-exynos7870-drm-dts-v1-0-88c0779af6cb@disroot.org

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: using specified base-commit 1b152eeca84a02bdb648f16b82ef3394007a9dcf

If this is not the correct base, please add 'base-commit' tag

Don't you need to add this to 'compatible' and under 'select'?

compatible: [1]

samsung,exynos7-pmu is under select. 7870 has a fallback on 7.
Do you think samsung,exynos7-pmu should've been added in this patch
instead?

If this uses exynos7-pmu as fallback then it is fine. This should be in
commit msg - that's the point of commit msg - explain the hardware and
things not easily visible, instead of repeating what is visible in the diff.

What is the status of the bindings from dependencies? I think they were
not accepted.

I also replied with few nits for one of DTS patches. Everything else
looks fine.

BTW, really great job you did here, I am impressed!

x-names followed by x approach is followed by the entire dts.
I will apply your suggestion in the next rev, and will also send a
separate patch for the same in all other places.

Except panel-synaptics-tddi, all have been accepted. A lot of them
haven't hit next though. I'm waiting for that to send the next revision.
This rev is pretty old, so the links are old revs too.

There's also another related patch, on the IOMMU driver, which has also
been accepted. I will also add it to the list.

Thank you! This was quite a ride to work on it and upstream these
patches. Thanks again to you and other kernel maintainers for all the
reviews.

What does it mean - accepted but not hit next? If it is accepted, it
must be visible in next. Which maintainer's tree are not in the next?

drm-exynos [1] branches haven't been rebased to v6.17-rc1. This should
include all some DECON and all DSIM patches.

Although [2] has been accepted, I don't see the commit in [3] anymore.
But, there's [4] which mentions my panel patches, but then I don't see
them in next (there should be a panel-samsung-s6e8aa5x01-ams561ra01.c
in [5]).

I don't understand this. How can you find a commit via web interface?
You should be having linux-next and there you can go through the history
to check if commit is there or not.

so that's the problem to solve.

I'll drop the patchset from my queue. I think you got here some other
comments as well, so I will be expecting v3 anyway.
