Subject: [PATCH 6/6] dt-bindings: drm/panel: simple: Innolux TV123WAM is actually P120ZDG-BF1
Date: Mon, 22 Oct 2018 13:46:39 -0700 [thread overview]
Message-ID: <20181022204639.8558-6-dianders@chromium.org> (raw)
In-Reply-To: <20181022204639.8558-1-dianders@chromium.org>
As far as I can tell the bindings that were added in commit
9c04400f7ea6 ("dt-bindings: drm/panel: Document Innolux TV123WAM panel
bindings") weren't actually for Innolux TV123WAM but were actually for
Innolux P120ZDG-BF1.
As far as I can tell the Innolux TV123WAM isn't a real panel and but
it's a mosh between the TI TV123WAM and the Innolux P120ZDG-BF1.
Let's unmosh.
Here's my evidence:
* Searching for TV123WAM on the Internet turns up a TI panel. While
it's possible that an Innolux panel has the same model number as the
TI Panel, it seems a little doubtful. Looking up the datasheet from
the TI Panel shows that it's 1920 x 1280 and 259.2 mm x 172.8 mm.
* As far as I know, the patch adding the Innolux Panel was supposed to
be for the board that's sitting in front of me as I type this
(support for that board is not yet upstream). On the back of that
panel I see Innolux P120ZDZ-EZ1 rev B1.
* Someone pointed me at a datasheet that's supposed to be for the
panel in front of me (sorry, I can't share the datasheet). That
datasheet has the string "p120zdg-bf1"
* If I search for "P120ZDG-BF1" on the Internet I get hits for panels
that are 2160x1440. They don't have datasheets, but the fact that
the resolution matches is a good sign.
While we doing the rename, also mention that no-hpd can be used with
this panel. See the previous patch in this series ("drm/panel:
simple: Add "no-hpd" delay for Innolux TV123WAM").

This binding is compatible with the simple-panel binding, which is specified
in simple-panel.txt in this directory.
Required properties:
-- compatible: should be "innolux,tv123wam"
+- compatible: should be "innolux,p120zdg-bf1"
- power-supply: regulator to provide the supply voltage
Optional properties:
- enable-gpios: GPIO pin to enable or disable the panel
- backlight: phandle of the backlight device attached to the panel
+- no-hpd: If HPD isn't hooked up; add this property.
Example:
panel_edp: panel-edp {
- compatible = "innolux,tv123wam";
+ compatible = "innolux,p120zdg-bf1";
enable-gpios = <&msmgpio 31 GPIO_ACTIVE_LOW>;
power-supply = <&pm8916_l2>;
backlight = <&backlight>;
+ no-hpd;
};
