2023-07-24drm/bridge: anx7625: Drop device lock before drm_helper_hpd_irq_event()Chen-Yu Tsai
The device lock is used to serialize the low level power sequencing operations. Since drm_helper_hpd_irq_event() could end up calling .atomic_enable, which also calls power sequencing functions through runtime PM, this results in a real deadlock. This was observed on an MT8192-based Chromebook's external display (with appropriate patches [1] and DT changes applied). Move the drm_helper_hpd_irq_event() call outside of the lock range. The lock only needs to be held so that the device status can be read back. This is the bare minimum change to avoid the deadlock. The lock could be dropped completely and have pm_runtime_get_if_in_use() increase the reference count, but this is not the same as pm_runtime_suspended(). Dropping the lock completely also causes the internal display of the same device to not function correctly if the internal bridge's interrupt line is added in the device tree. Both the internal and external display of said device each use one anx7625 bridge.

Now that fbdev core has been split in FB_CORE and FB, make the DRM symbol to select the FB_CORE option if the DRM fbdev emulation layer is enabled.

2023-07-22fbdev: Split frame buffer support in FB and FB_CORE symbolsJavier Martinez Canillas
Currently the CONFIG_FB option has to be enabled even if no legacy fbdev drivers are needed (e.g: only to have support for framebuffer consoles). The DRM subsystem has a fbdev emulation layer, but depends on CONFIG_FB and so it can only be enabled if that dependency is enabled as well. That means fbdev drivers have to be explicitly disabled if users want to enable CONFIG_FB, only to use fbcon and/or the DRM fbdev emulation layer. This patch introduces a non-visible CONFIG_FB_CORE symbol that could be enabled just to have core support needed for CONFIG_DRM_FBDEV_EMULATION, allowing CONFIG_FB to be disabled (and automatically disabling all the fbdev drivers). Nothing from fb_backlight.o and fbmon.o is used by the DRM fbdev emulation layer so these two objects can be compiled out when CONFIG_FB is disabled.

2023-07-21drm/bridge: tc358767: give VSDELAY some positive valueDavid Jander
The documentation is not clear about how this delay works. Empirical tests have shown that with a VSDELAY of 0, the first scanline is not properly formatted in the output stream when DSI->DP mode is used. The calculation spreadsheets from Toshiba seem to always make this value equal to the HFP + 10 for DSI->DP use-case. For DSI->DPI this value should be > 2 and for DPI->DP it seems to always be 0x64.

2023-07-21drm/arm/komeda: Remove component framework and add a simple encoderFaiz Abbas
The Komeda driver always expects the remote connector node to initialize an encoder. It uses the component aggregator framework which consists of component->bind() calls used to initialize the remote encoder and attach it to the crtc. This makes it incompatible with connector drivers which implement drm_bridge APIs. Remove all component framework calls from the komeda driver and declare and attach an encoder inside komeda_crtc_add(). The remote connector driver has to implement the DRM bridge APIs which can be used to glue the encoder to the remote connector. Since we usually pair this with a component encoder that also implements a drm_bridge, dropping support is not expected to affect users of this driver.

2023-07-21gpu: host1x: Stop open-coding of_device_uevent()Miquel Raynal
There is apparently no reasons to open-code of_device_uevent() besides: - The helper receives a struct device while we want to use the of_node member of the struct device *parent*. - of_device_uevent() could not be called by modules because of a missing EXPORT_SYMBOL*(). In practice, the former point is not very constraining, just calling of_device_uevent(dev->parent, ...) would have made the trick. The latter point is more an observation rather than a real blocking point because nothing prevented of_uevent() (called by the inline function of_device_uevent()) to be exported to modules. In practice, this helper is now exported, so nothing prevent us from using of_device_uevent() anymore. Let's use the core helper directly instead of open-coding it.

2023-07-21of: module: Export of_device_uevent()Miquel Raynal
The content of of_device_uevent() is currently hardcoded in a driver that can be compiled as a module. Nothing prevents of_device_uevent() to be exported to modules, most of the other helpers in of/device.c actually are. The reason why this helper was not exported is because it has been so far only useful in drivers/base, which is built-in anyway. With the idea of getting rid of the hardcoded implementation of of_device_uevent() in other places in the kernel, let's export it to GPL modules (very much like its cousins in the same file).

2023-07-20drm/syncobj: add IOCTL to register an eventfdSimon Ser
Introduce a new DRM_IOCTL_SYNCOBJ_EVENTFD IOCTL which signals an eventfd from a syncobj. This is useful for Wayland compositors to handle wait-before-submit. Wayland clients can send a timeline point to the compositor before the point has materialized yet, then compositors can wait for the point to materialize via this new IOCTL. The existing DRM_IOCTL_SYNCOBJ_TIMELINE_WAIT IOCTL is not suitable because it blocks. Compositors want to integrate the wait with their poll(2)-based event loop.
