Pull drm updates from Dave Airlie: "This is the main pull request for the drm subsystems for 6.10. In drivers the main thing is a new driver for ARM Mali firmware based GPUs, otherwise there are a lot of changes to amdgpu/xe/i915/msm and scattered changes to everything else. In the core a bunch of headers and Kconfig was refactored, along with the addition of a new panic handler which is meant to provide a user friendly message when a panic happens and graphical display is enabled.

2024-05-02Revert "drm: Switch DRM_DISPLAY_HELPER to depends on"Geert Uytterhoeven1-10/+10
This reverts commit e075e496f516bf92bc0cbaf94d64e8d4a6b58321, as helper code should always be selected by the driver that needs it, for the convenience of the final user configuring a kernel. The user who configures a kernel should not need to know which helpers are needed for the driver he is interested in. Making a driver depend on helper code means that the user needs to know which helpers to enable first, which is very user-unfriendly.

G121XCE-L01 is a Color Active Matrix Liquid Crystal Display composed of a TFT LCD panel, a driver circuit, and LED backlight system.

All input signals are LVDS interface compatible.

2024-04-07drm-panel: If drm_panel_dp_aux_backlight() fails, don't fail panel probeDouglas Anderson2-3/+14
If we're using the AUX channel for eDP backlight and it fails to probe for some reason, let's _not_ fail the panel probe. At least one case where we could fail to init the backlight is because of a dead or physically missing panel. As talked about in detail in the earlier patch in this series, ("drm/panel-edp: If we fail to powerup/get EDID, use conservative timings"), this can cause the entire system's display pipeline to fail to come up and that's non-ideal. If we fail to init the backlight for some transitory reason, we should dig in and see if there's a way to fix this (perhaps retries?). Even in that case, though, having a panel whose backlight is stuck at 100% (the default, at least in the panel Samsung ATNA33XC20 I tested) is better than having no panel at all.

2024-04-07drm/panel-edp: If we fail to powerup/get EDID, use conservative timingsDouglas Anderson1-5/+7
If at boot we fail to power up the eDP panel (most often happens if the eDP panel never asserts HPD to us) or if we are unable to read the EDID at bootup to figure out the panel's ID then let's use the conservative eDP panel powerup/powerdown timings but _not_ fail the probe. It might seem strange to _not_ fail the probe in this case since we were unable to powerup the panel and confirm it's there. However, there is a reason to do this. Specifically, if we fail to probe the panel then it really throws the whole display pipeline for loop. Most DRM subsystems are written so that they wait until all components (including the panel) have probed before they set everything up. When the panel doesn't come up then this never happens. As a side effect of not setting everything up then other display adapters don't get initialized. As a practical example, I can see that if I open up a sc7180-trogdor based Chromebook that's using the generic "edp-panel" and unplug the eDP panel that it causes the _external_ DP monitor not to function. This is obviously bad because it means that a device with a dead eDP panel becomes e-waste when it could instead still be given useful life with an external display. NOTES: - When we fail to probe like this, boot is a bit slow because we try several times to power the panel up. This doesn't feel horrible because it'll eventually work and the retries are known to help bring some panels up. - In the case where we hit the condition of failing to power up, the display will likely _never_ have a chance to work again until reboot. Once the panel-edp pm_runtime resume function fails it doesn't ever seem to retry. This is probably for the best given that we don't have any real timing/modes. eDP isn't expected to be "hotplugged" so this makes some sense. - It turns out that this makes panel-edp behave more similarly for users of the generic "edp-panel" compatible string and the old fixed panel compatible string. With the old fixed panel compatible string we don't talk to the panel during probe so we'd actually behave much the same way that we'll now behave for the generic "edp-panel".

If we're using the generic "edp-panel" compatible string and we fail to detect an eDP panel then we fall back to conservative timings for powering up and powering down the panel. Abstract out the function for setting these timings so it can be used in future patches. No functional change expected--just code movement.
