* drm/panel-simple: Add Vivax TPC-9150 panel v6Nikola Pavlica2021-10-141-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The model and make of the LCD panel of the Vivax TPC-9150 is unknown, hence the panel settings that were retrieved with a FEX dump are named after the device NOT the actual panel. The LCD in question is a 50 pin MISO TFT LCD panel of the resolution 1024x600 used by the aforementioned device. Version 2, as Thierry kindly suggested that I fix the order in which the panel was ordered compared to others. Version 3, filling in the required info suggested by Sam. Plus some factual issues that I've corrected myself (tested working) Version 4, rearranged the display parameters and fix invalid bit format issue. (Thanks Sam) Version 5, referred to FEX file instead of manual debugging for information. Version 6, same as above. This time, it'll be documented. A bit of context first: I experimented with this a long time ago whilst I was first learning how to get Linux running on Allwinner boards, I didn't have many resources at hand so this was quite slow. Anyways, I stumbled upon this guide (https://linux-sunxi.org/LCD) and was reading about how to setup the LCD for my tablet. Since I was able to make a proper FEX dump, I was also able to read the correct parameters for myself without relying on leaked documents or part numbers and whatnot. In the FEX dump the value lcd_frm IS SET to 1, which means, at least according to the document, that this display is INDEED an 18 bit per pixel panel. Compiling U-Boot and seeing the tux in proper colors confirmed this. As per Sam Ravnborg's suggestion, I've changed the panel to his format "MEDIA_BUS_FMT_RGB666_1X7X3_SPWG", however this does not lead to any actual change in regards to the functionality since the sunxi panel driver just ignores this value. However, hopefully this clears up any errors down the road as either the driver becomes advanced enough to not ignore this value or that some other piece of software relies on this value being known. PS: Apologies to the maintainers that have to endure my misjudgement about how these things work. As for the concerns about a single patch series, I wasn't sure where to send the patches as they clearly aren't dt-bindings related and my previous patches have ended up in drm-misc-fixes anyway. So I'm guessing I'll be fine if I just post them in the list from last time???

| | | | | | | | | | | | All of the "HPD" handling added to panel-simple recently was for eDP panels. Remove it from panel-simple now that panel-edp handles eDP panels.

* drm/panel-edp: Move some wayward panels to the eDP driverDouglas Anderson2021-09-201-365/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not all panels in panel-simple were marked what type of panel they were. I searched through ARM/ARM64 Chromebooks or Chromebook-related reference boards that I was aware of and found some panels that needed to be moved. I also skimmed for panels that had no mode and were "big" since it's quite rare to see a small eDP panel. Here's what I found: * auo,b101ean01 - rk3288-veyron-minnie * auo,b133htn01 - exynos5800-peach-pi * auo,b133xtn01 - tegra124-nyan-big * boe,nv101wxmn51 - rk3399-gru-bob * innolux,p120zdg-bf1 - sdm845-cheza * lg,lp079qx1-sp0v - rk3399-evb and similar * lg,lp097qx1-spa1 - According to commit 0355dde26e52 ("drm/panel: simple: Add support for LG LP097QX1-SPA1 panel") this is an eDP panel. * lg,lp129qe - tegra124-venice2 * samsung,lsn122dl01-c01 - According to commit 0330eaf39082 ("drm/panel: simple: Add support for Samsung LSN122DL01-C01 panel") this is an eDP panel. * samsung,ltn140at29-301 - tegra124-nyan-blaze * sharp,ld-d5116z01b - According to commit cd5e1cbe1f0a ("drm/panel: simple: Add support for Sharp LD-D5116Z01B panel") this is an eDP panel. * sharp,lq123p1jx31 - rk3399-gru-kevin * starry,kr122ea0sra - rk3399-gru-gru (reference board, not upstream) I won't promise that I didn't miss a single panel, but that's fairly complete I think. I'm not sure the full impact of the fact that they didn't have the connector type specified, but at least as of commit 9f069c6fbc72 ("drm/panel: panel-simple: add default connector_type") we may have been accidentally thinking of them as DPI panels. We also would certainly have had a warning. In any case since we don't want to support anything eDP in the old simple-panel driver, we should move these.

* drm/panel-edp: Split eDP panels out of panel-simpleDouglas Anderson2021-09-201-564/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The panel-simple driver handles way too much. Let's start trying to get a handle on it by splitting out the eDP panels. This patch does this: 1. Start by copying simple-panel verbatim over to a new driver, simple-panel-edp. 2. Rename "panel_simple" to "panel_edp" in the new driver. 3. Keep only panels marked with `DRM_MODE_CONNECTOR_eDP` in the new driver. Remove those panels from the old driver. 4. Remove all recent "DP AUX bus" stuff from the old driver. The DP AUX bus is only possible on DP panels. 5. Remove all DSI / MIPI related functions from the new driver. 6. Remove bus_format / bus_flags from eDP driver. These things don't seem to make any sense for eDP panels so let's stop filling in made up stuff. In the end we end up with a bunch of duplicated code for now. Future patches will try to address _some_ of this duplicated code though some of it will be unavoidable. NOTE: This may not actually move all eDP panels over to the new driver since not all panels were properly marked with `DRM_MODE_CONNECTOR_eDP`. A future patch will attempt to move wayward panels I could identify but even so there may be some missed.

Those delays were added to support the Samsung ATNA33XC20 panel. However, we've moving that to its own panel driver and out of panel-simple. That means we don't need the ability to specify this delay. NOTE: it's unlikely we want to keep this delay "just in case" some other panel needs it. The enable-gpio and the power supply are really supposed to be different ways to specify the same thing: the main enable of the panel. Supporting a delay between them doesn't really make sense.

This panel's power sequencing really can't be handled properly by panel-simple because of the special sequencing needed for the EL_ON3 GPIO. The only way it was sorta working in the past was by trying to jam that signal into the "enable-gpio", but that really wasn't a good fit. We'll add a custom panel driver for this panel to do it right.

* drm/panel: panel-simple: Power the panel when reading the EDIDDouglas Anderson2021-05-031-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | I don't believe that it ever makes sense to read the EDID when a panel is not powered and the powering on of the panel is the job of prepare(). Let's make sure that this happens before we try to read the EDID. We use the pm_runtime functions directly rather than directly calling the normal prepare() function because the pm_runtime functions are definitely refcounted whereas it's less clear if the prepare() one is. NOTE: I'm not 100% sure how EDID reading was working for folks in the past, but I can only assume that it was failing on the initial attempt and then working only later. This patch, presumably, will fix that. If some panel out there really can read the EDID without powering up and it's a big advantage to preserve the old behavior we can add a per-panel flag. It appears that providing the DDC bus to the panel in the past was somewhat uncommon in any case.

| | | | | | | | | | | | | | | | | | | | | When I added support for the hpd-gpio to simple-panel in commit 48834e6084f1 ("drm/panel-simple: Support hpd-gpios for delaying prepare()"), I added a special case to handle a circular dependency I was running into on the ti-sn65dsi86 bridge chip. On my board the hpd-gpio is actually provided by the bridge chip. That was causing some circular dependency problems that I had to work around by getting the hpd-gpio late. I've now reorganized the ti-sn65dsi86 bridge chip driver to be a collection of sub-drivers. Now the GPIO part can probe separately and that breaks the chain. Let's get rid of the old code to clean things up.

* drm/panel: panel-simple: Add missing pm_runtime_disable() callsDouglas Anderson2021-04-301-1/+4
| | | | | | | | | | | | | | In commit 3235b0f20a0a ("drm/panel: panel-simple: Use runtime pm to avoid excessive unprepare / prepare") we started using pm_runtime, but my patch neglected to add the proper pm_runtime_disable(). Doh! Add them now.
