No supplies? Still need to list power-supply here if so, so it is clear 
that this display has a single supply (or you need to list multiple ones 
if not).

I took the same approach as several other simple panels having
description in Documentation/devicetree/bindings/display/panel/*
directory (e.g. innolux,g121i1-l01.txt) .

In the description it is stated that this binding is compatible with
one documented in the simple-panel.txt, which defines following
properties:

Required properties:
- power-supply: regulator to provide the supply voltage

Optional properties:
- ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
- enable-gpios: GPIO pin to enable or disable the panel
- backlight: phandle of the backlight device attached to the panel


Do I need to do something more?

Yes. How do I know this panel has a single power supply vs. it has
multiple supplies and you haven't thought about supplies yet or they
aren't s/w controlled on some boards. The latter is frequently the
case when I go read the datasheets.

And yes there are examples that don't do this, but we're stricter now.

Is there a chance that this patch will find its way to v4.15-rc1 ?

No, that's very unlikely. We're in the middle of the merge window, no
new patches are accepted at that point.

If you want to make sure a patch goes into the next release, make sure
it is posted and reviewed at least a few days before -rc6 of the prior
release. -rc6 is a common cut-off point for subsystems (though not all)
in the kernel.

Ok. I see. I should have sent the ping earlier.

Looking at the timeline of this patch even that wouldn't have been
enough. You sent the original patch on October 21, which is one day
after the final drm-misc feature pull request was tagged. So this
wouldn't have made it into v4.15-rc1 no matter how early you would
have pinged. =)

Looking at the timeline of this patch even that wouldn't have been
enough. You sent the original patch on October 21, which is one day
after the final drm-misc feature pull request was tagged. So this
wouldn't have made it into v4.15-rc1 no matter how early you would
have pinged. =)

I've applied this, though I had to make a few modifications. First, I
added a commit message. Commits should always have one.

Also, please send DT bindings and driver changes as separate patches in
the future.

Device tree bindings should have a subject prefixed with any of these:

	dt-bindings:
	dt-bindings: display:
	dt-bindings: display: panel:

Though the latter two are fairly long by themselves, so you don't have a
lot of room for the important bits.

Please also prefix the subject of panel driver patches with a:

	drm/panel:

Which makes it easier to identify relevant patches among loads and loads
of other email.

Looks like these are actually sorted correctly in your patch. However,
when applying these got added after the Toshiba panel that was recently
added, so I resorted again.
