2024-02-28drm/dp: Don't attempt AUX transfers when eDP panels are not poweredDouglas Anderson
If an eDP panel is not powered on then any attempts to talk to it over the DP AUX channel will timeout. Unfortunately these attempts may be quite slow. Userspace can initiate these attempts either via a /dev/drm_dp_auxN device or via the created i2c device. Making the DP AUX drivers timeout faster is a difficult proposition. In theory we could just poll the panel's HPD line in the AUX transfer function and immediately return an error there. However, this is easier said than done. For one thing, there's no hard requirement to hook the HPD line up for eDP panels and it's OK to just delay a fixed amount. For another thing, the HPD line may not be fast to probe. On parade-ps8640 we need to wait for the bridge chip's firmware to boot before we can get the HPD line and this is a slow process. The fact that the transfers are taking so long to timeout is causing real problems. The open source fwupd daemon sometimes scans DP busses looking for devices whose firmware need updating. If it happens to scan while a panel is turned off this scan can take a long time. The fwupd daemon could try to be smarter and only scan when eDP panels are turned on, but we can also improve the behavior in the kernel. Let's let eDP panels drivers specify that a panel is turned off and then modify the common AUX transfer code not to attempt a transfer in this case.

2024-01-08drm/panel-edp: use put_sync in unprepareHsin-Yi Wang
Some edp panel requires T10 (Delay from end of valid video data transmitted by the Source device to power-off) less than 500ms. Using autosuspend with delay set as 1000 violates this requirement. Use put_sync_suspend in unprepare to meet the spec. For other cases (such as getting EDID), it still uses autosuspend.

2023-12-18drm/panel-edp: Add some panels with conservative timingsPin-yen Lin
These panels are used by Mediatek MT8173 Chromebooks, and they used to work with the downstream v4.19 kernel without any specified delay. Back in the v4.19 kernel, they used the "little white lie" approach, which is making the devicetree claim a specific panel's compatible string for many different panels. That was a common solution before the generic edp-panel driver. After we uprevved the device to a newer kernel and used the edp-panel driver, we saw multiple devices reporting warnings of using an unknown panel and falling back to the conservative timings, which means that they turn on/off much more slowly than they should. We tried to fill in the timings for those panels, but we failed to find all the data sheets for them. Therefore, instead of having them use the default conservative timings, update them with less-conservative timings from other panels of the same vendor. The panels should still work under those timings, and we can save some delays and suppress the warnings.

2023-10-12drm/panel: Move AUX B116XW03 out of panel-edp back to panel-simpleDouglas Anderson
In commit 5f04e7ce392d ("drm/panel-edp: Split eDP panels out of panel-simple") I moved a pile of panels out of panel-simple driver into the newly created panel-edp driver. One of those panels, however, shouldn't have been moved. As is clear from commit e35e305eff0f ("drm/panel: simple: Add AUO B116XW03 panel support"), AUX B116XW03 is an LVDS panel. It's used in exynos5250-snow and exynos5420-peach-pit where it's clear that the panel is hooked up with LVDS. Furthermore, searching for datasheets I found one that makes it clear that this panel is LVDS. As far as I can tell, I got confused because in commit 88d3457ceb82 ("drm/panel: auo,b116xw03: fix flash backlight when power on") Jitao Shi added "DRM_MODE_CONNECTOR_eDP". That seems wrong. Looking at the downstream ChromeOS trees, it seems like some Mediatek boards are using a panel that they call "auo,b116xw03" that's an eDP panel. The best I can guess is that they actually have a different panel that has similar timing. If so then the proper panel should be used or they should switch to the generic "edp-panel" compatible. When moving this back to panel-edp, I wasn't sure what to use for .bus_flags and .bus_format and whether to add the extra "enable" delay from commit 88d3457ceb82 ("drm/panel: auo,b116xw03: fix flash backlight when power on"). I've added formats/flags/delays based on my (inexpert) analysis of the datasheet. These are untested. NOTE: if/when this is backported to stable, we might run into some trouble. Specifically, before 474c162878ba ("arm64: dts: mt8183: jacuzzi: Move panel under aux-bus") this panel was used by "mt8183-kukui-jacuzzi", which assumed it was an eDP panel. I don't know what to suggest for that other than someone making up a bogus panel for jacuzzi that's just for the stable channel.

2023-05-30drm/panel-edp: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. panel_edp_remove() always returned zero, so convert it to return void without any loss and then just drop the return from panel_edp_platform_remove().

2022-11-29drm/panel-edp: Use ktime_get_boottime for delaysDrew Davenport
ktime_get is based on CLOCK_MONOTONIC which stops on suspend. On suspend, the time that the panel was powerd off is recorded with ktime_get, and on resume this time is compared to the current ktime_get time to determine if the driver should wait for the panel to power down completely before re-enabling it. Because we're using ktime_get, this delay doesn't account for the time that the device is suspended, during which the power down delay may have already elapsed. Change to use ktime_get_boottime throughout, which uses CLOCK_BOOTTIME which does not stop when suspended. This ensures that the resume path will not be delayed if the power off delay has already been met while the device is suspended.

2022-09-29drm/panel: panel-edp: Use dev_err_probe() to simplify codeYuan Can
In the probe path, dev_err() can be replaced with dev_err_probe() which will check if error code is -EPROBE_DEFER and prints the error name. It also sets the defer probe reason which can be checked later through debugfs.

2022-09-08drm/panel-edp: Fix delays for Innolux N116BCA-EA1Chen-Yu Tsai
Commit 52824ca4502d ("drm/panel-edp: Better describe eDP panel delays") clarified the various delays used for eDP panels, tying them to the eDP panel timing diagram. For Innolux N116BCA-EA1, .prepare_to_enable would be: t4_min + t5_min + t6_min + max(t7_max, t8_min) Since t4_min and t5_min are both 0, the panel can use either .enable or .prepare_to_enable. As .enable is better defined, switch to using .enable for this panel. Also add .disable = 50, based on the datasheet's t9_min value. This effectively makes the delays the same as delay_200_500_e80_d50.
