2022-11-10drm/panel: simple: set bpc field for logic technologies displaysAishwarya Kothari
In case bpc is not set for a panel it then throws a WARN(). Add bpc to the panels logictechno_lt170410_2whc and logictechno_lt161010_2nh.

Pull drm updates from Dave Airlie: "Lots of stuff all over, some new AMD IP support and gang submit support. i915 has further DG2 and Meteorlake pieces, and a bunch of i915 display refactoring. msm has a shrinker rework. There are also a bunch of conversions to use kunit. This has two external pieces, some MEI changes needed for future Intel discrete GPUs. These should be acked by Greg. There is also a cross maintainer shared tree with some backlight rework from Hans in here. Core: - convert selftests to kunit - managed init for more objects - move to idr_init_base - rename fb and gem cma helpers to dma - hide unregistered connectors from getconnector ioctl - DSC passthrough aux support -

2022-07-09drm/mipi-dsi: Make remove callback return voidUwe Kleine-König
All implementations return 0 and the return value of mipi_dsi_drv_remove() is ignored anyhow. So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour.

If function panel_dpi_probe() is called panel->desc will be updated, but further on only desc will be evaluated.

2021-10-14drm/panel-simple: Add Vivax TPC-9150 panel v6Nikola Pavlica
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???

2021-09-20drm/panel-edp: Move some wayward panels to the eDP driverDouglas Anderson
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.

2021-09-20drm/panel-edp: Split eDP panels out of panel-simpleDouglas Anderson
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.

This reverts commit 18a1488bf1e13fc3fc96d7948466b2166067c6c8. 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.
