[PATCH v2 0/3] panel-simple: add support for Crystal Clear CMT430B19N00

[Jérémie Dautheribes]

Hello everyone,

This patch series add support for the Crystal Clear Technology
CMT430B19N00 4.3" 480x272 TFT-LCD panel.
It also adds Crystal Clear Technology to vendor-prefixes.yaml.

Please note that unfortunately there is no public datasheet available
for this panel.

Changes in v2:
  - add link to the Crystal Clear Technology website in commit message, as
  suggested by Conor Dooley and Neil Armstrong.


Regards,

Jérémie

[PATCH v2 1/3] dt-bindings: Add Crystal Clear Technology vendor prefix

[Jérémie Dautheribes]

Update Documentation/devicetree/bindings/vendor-prefixes.yaml to
include "cct" as a vendor prefix for "Crystal Clear Technology". CCT is
the vendor of the CMT430B19N00 TFT-LCD panel.

Your pixel clock doesn't really match the rest of the timings:

(480 + 43 + 8 + 4) * (272 + 12 + 8 + 4) * 60 = 9501600

So a ~6% deviation.

What does the datasheet say?

Indeed it does not exactly match but the datasheet indicates that the 
typical clock frequency is 9MHz and when this frequency is used, the 
typical values of the other parameters are those we have defined in the 
drm_display_mode structure. I don't see any information about the 
accepted deviation either.

It seems weird to me that all the typical timings end up in a
non-typical configuration, but I've seen my fair share of weird
datasheet, so.. yeah.

I guess the best thing to do if you have access to the min/typ/max
timings is to actually use the display_timings structure here and define
all of them.

It at least gives us the opportunity to fix it later on.

> I don't see any information about the accepted deviation either.

It's not only about the panel itself. 6% gives your roughly 56fps when
you meant 60. This can then trip up some applications too. Like if
you're playing a 60fps application, it will either play too fast or
you'll get stutter, depending on how the video playback has been
implemented exactly.

Yes, I do have access to these timings, I'm going to implement the 
display_timing structure as you suggested, thank you!

I was wondering why my scripts said this was already reviewed with that 
missing. Turns out b4 will now check prior versions and add the tags as 
long as the patch-id matches. Neat, but the submitter really has to 
grasp how that all works (knowing if the patch-id changed) as well as 
the maintainer has to use b4, so we can't really rely on it.

Here's b4 debug log:

This is the other nice thing that b4 does, pick up "non review"
trailers too.

Oops you are right, I'm sorry. Should I send a v3 containing these acks?

I was going to just provide them here, I just wanted to make sure you
didn't intentionally drop them first. But in the interim you got some

I wouldn't bother adding the forgotten acks or resending, I don't care
about my ack count :)
