This device tree cooked a while in our repository and is now quite
complete. All is tested on several Colibri T30 modules and
evaluation boards by Marcel and me. The device tree is splitted
into a module part and the carrier board. The former is then
included by the latter (in this case the evaluation board). The
comments "Colibri: " represent the SO-DIMM Pin name as defined
in the Colibri standard, and should be helpful for users
adopting the device tree for other carrier boards.
The second revision has one new patch which adds Toradex default
demo panels to the simple-panel driver. One could argue that those
panels are not actually part of the evaluation board, but when
customer build something with TFT panels they usually are integrated
into one system. Hence I descided to add them to the evaluation board
as well to have such a complete system, including TFT panel.
Note: Patch 1 is already applied!
Changes since v1:
- Extended with two TFT LCD panels from EDT
- Removed version specific compatible string and add modules compatible
string in the carrier board file
- Removed serial alias and dr_mode property from USB controller
- Removed PMC status since this is enabled in tegra30.dtsi
- Lowered voltage of VDD_CPU to 1.15V again (tests were done with 1.15V)
- Added pinmux for lcd_m1 which makes data enable based panels working

Its etm0700g0dh6 vs. et070080dh6, Philipp's panel is with captive multi touch, (hence the M I guess). The panel itself really looks the same. I found this overview of EDT displays: http://www.dmbtechnics.com/scripts/passthru.php?id=7 There seem to be quite a lot variants with the same panel... Regarding timings, I just checked the documentation, Philipp's timing really matches the documented ones, I miscalculated the vertical back porch. How do we resolve that? I would suggest that I split out that patch and remove the et070080dh6 panel and send the other as a single patch to the dri-devel mailing list as well. Philipp, could you add my display type (et070080dh6) to the compatible list of your mode/panel entry? Does this sound reasonable? -- Stefan ^ permalink raw reply [flat|nested] 15+ messages in thread

Okay, so that means that the panel works for you with the same timings that Philipp has in the ETM0700G0DH6 patch? If so then I definitely think we should be sharing the timings in the driver by making the two compatible entries point to the same driver data. > How do we resolve that? > > I would suggest that I split out that patch and remove the et070080dh6 > panel and send the other as a single patch to the dri-devel mailing list > as well. Yes, that would work. > Philipp, could you add my display type (et070080dh6) to the compatible > list of your mode/panel entry? I also noticed that Philipp's patch doesn't actually introduce the device tree bindings, so that will have to be added as well.

The ETM0700G0DH6 Datasheet lists 2 lines as the typical vsync pulse width, 525 lines as the vertical period, and 35 lines as the vsync -de time, which is vsync len + back porch. So vertical timings 480 + 10 + 2 + 33 = 525 should be valid for the ET0700G0DH6 panel: https://www.glynshop.com/erp/owweb/Daten/DSS/EDT/Products/Specifications/Active%20Displays/ET0700G0DH6.pdf et070080dh6 I have not seen the data sheet for ET070080DH6. regards Philipp ^ permalink raw reply [flat|nested] 15+ messages in thread

It seems to me that it should still be safe for that panel. Similarily I'd expect your timings to work on the ET070080DH6. Irrespective of that they both seem to have different capabilities so two compatible values should be fine. However for the purpose of the simple panel driver they could be made to share the same timings if it works for both panels and devices. As for the touch panel on the ETM0700G0DH6, do you happen to know how that's usually connected? I suspect it needs external hardware to capture the YU, XL, YD and XR pins and turn that into raw coordinates and pen down interrupts.

As I understand, the 480 + 10 + 2 + 33 timing should be correct for both panels. > As for the touch panel on the ETM0700G0DH6, do you happen to know how > that's usually connected?

The ETM0700G0DH6 has a capacitive touch screen with an EDT-FT5406 controller connected via I2C, at least on the panels that I have seen. regards Philipp ^ permalink raw reply [flat|nested] 15+ messages in thread

For Colibri Evaluation Board, those pins are routed to the generic 4-wire pins of the Colibri SO-DIMM. On the Colibri T30 module, those pins are connected to a STMPE811. I also added that to the device tree once, however it does not work properly atm, I need to debug this and will send a patch at a later time. -- Stefan ^ permalink raw reply [flat|nested] 15+ messages in thread

The module consists of a Tegra 30 SoC, two PMIC, DDR3L RAM, eMMC, a LM95245 temperature sensor and an AX88772B USB Ethernet Controller. Furthermore, there is a STMPE811 and SGTL5000 audio codec which are not yet supported. Anything that is not self contained on the module is disabled by default. The device tree for the Evaluation Board includes the modules device tree and enables the supported pheripherials of the carrier board (the Evaluation Board supports almost all of them).

I've applied this to Tegra's for-3.16/dt branch. A changelog in each individual patch would be useful. Splitting out patches for the DRM tree and the Tegra tree into different series would be useful. In this case, they don't depend on each-other. ^ permalink raw reply [flat|nested] 15+ messages in thread
