2020-07-26drm: panel: simple: Delay HPD checking on boe_nv133fhm_n61 for 15 msDouglas Anderson
On boe_nv133fhm_n62 (and presumably on boe_nv133fhm_n61) a scope shows a small spike on the HPD line right when you power the panel on. The picture looks something like this: +-------------------------------------- | | | Power ---+ +--- | ++ | +----+| | HPD -----+ +---------------------------+ So right when power is applied there's a little bump in HPD and then there's small spike right before it goes low. The total time of the little bump plus the spike was measured on one panel as being 8 ms long. The total time for the HPD to go high on the same panel was 51.2 ms, though the datasheet only promises it is < 200 ms. When asked about this glitch, BOE indicated that it was expected and persisted until the TCON has been initialized. If this was a real hotpluggable DP panel then this wouldn't matter a whole lot. We'd debounce the HPD signal for a really long time and so the little blip wouldn't hurt. However, this is not a hotpluggable DP panel and the the debouncing logic isn't needed and just shows down the time needed to get the display working. This is why the code in panel_simple_prepare() doesn't do debouncing and just waits for HPD to go high once. Unfortunately if we get unlucky and happen to poll the HPD line right at the spike we can try talking to the panel before it's ready. Let's handle this situation by putting in a 15 ms prepare delay and decreasing the "hpd absent delay" by 15 ms. That means: * If you don't have HPD hooked up at all you've still got the hardcoded 200 ms delay. * If you've got HPD hooked up you will always wait at least 15 ms before checking HPD. The only case where this could be bad is if the panel is sharing a voltage rail with something else in the system and was already turned on long before the panel came up. In such a case we'll be delaying 15 ms for no reason, but it's not a huge delay and I don't see any other good solution to handle that case. Even though the delay was measured as 8 ms, 15 ms was chosen to give a bit of margin.

2020-05-09drm/panel-simple: Support hpd-gpios for delaying prepare()Douglas Anderson
People use panel-simple when they have panels that are builtin to their device. In these cases the HPD (Hot Plug Detect) signal isn't really used for hotplugging devices but instead is used for power sequencing. Panel timing diagrams (especially for eDP panels) usually have the HPD signal in them and it acts as an indicator that the panel is ready for us to talk to it. Sometimes the HPD signal is hooked up to a normal GPIO on a system. In this case we need to poll it in the correct place to know that the panel is ready for us. In some system designs the right place for this is panel-simple. When adding this support, we'll account for the case that there might be a circular dependency between panel-simple and the provider of the GPIO. The case this was designed for was for the "ti-sn65dsi86" bridge chip. If HPD is hooked up to one of the GPIOs provided by the bridge chip then in our probe function we'll always get back -EPROBE_DEFER. Let's handle this by allowing this GPIO to show up late if we saw -EPROBE_DEFER during probe. NOTE: since the gpio_get_optional() is used, if the "hpd-gpios" isn't there our variable will just be NULL and we won't do anything in prepare().

The BOE NV133FHM-N61 is documented in the original commit to be a 13.3" panel, but the size listed in our struct doesn't match. Specifically: math.sqrt(30.0 * 30.0 + 18.7 * 18.7) / 2.54 ==> 13.92 Searching around on the Internet shows that the size that was in the structure was the "Outline Size", not the "Display Area". Let's fix it. Also the Internet says that this panel supports 262K colors.

2020-03-07Revert "drm/panel: simple: Add support for Sharp LQ150X1LG11 panels"Peter Rosin
This reverts commit 0f9cdd743f7f8d470fff51b11250f02fc554cf1b. The interface of the panel is LVDS, not parallel. The color depth is RGB888, not RGB565. The panel has additional features, making it not so simple. The only user (upstream) of this panel is appropriately using panel-lvds.

2020-02-29drm/panel: simple: add panel-dpi supportSam Ravnborg
The panel-dpi compatible is a fallback that allows the DT to specify the timing. When matching panel-dpi expect the device tree to include the timing information for the display-panel. Background for this change: There are a lot of panels and new models hits the market very often. It is a lost cause trying to chase them all and users of new panels will often find them in situations that the panel they ues are not supported by the kernel. On top of this a lot of panels are customized based on customer specifications. Including the panel timing in the device tree allows for a simple way to describe the actual HW and use this description in a generic way in the kernel. This allows uses of proprietary panels, or panels which are not included in the kernel, to specify the timing in the device tree together with all the other HW descriptions. And thus, using the device tree it is then easy to add support for an otherwise unknown panel. The current support expect panels that do not require any delays for prepare/enable/disable/unprepare. Oleksandr Suvorov replied: I've just tested this patch on Apalis iMX6Q and Colibri iMX7D using panel settings from the following patch: https://lore.kernel.org/linux-arm-kernel/20200115123401.2264293-4-oleksandr.suvorov@toradex.com/ It works for me, thanks!

2020-02-29drm/panel: Add driver for Novatek NT35510-based panelsLinus Walleij
This adds a driver for panels based on the Novatek NT35510 display driver IC, such as the Hydis HVA40WV1 panel found in the Samsung GT-S7710. The NT35510 can be used with both internal and external backlight (such as GPIO backlight) so we support both: if no external backlight is found, we register a subdriver for the internal backlight.

The panel datasheet says that the panel samples at falling edge, but does not say anything about h/v sync signals. Testing shows that if the sync signals are driven on falling edge, the picture on the panel will be slightly shifted right. Setting sync drive edge to the same as data drive edge fixes this issue.
