During the initial MST probing an MST port's I2C device will be registered using the kdev of the DRM device as a parent. Later after MST Connection Status Notifications this I2C device will be re-registered with the kdev of the port's connector. This will also move inconsistently the I2C device's sysfs entry from the DRM device's sysfs dir to the connector's dir. Fix the above by keeping the DRM kdev as the parent of the I2C device. Ideally the connector's kdev would be used as a parent, similarly to non-MST connectors, however that needs some more refactoring to ensure the connector's kdev is already available early enough. So keep the existing (initial) behavior for now. Cc: <stable@vger.kernel.org> Signed-off-by:

The WARN below triggers during the removal of an MST port. The problem is that the parent device's (the connector's kdev) sysfs directory is removed recursively when the connector is unregistered (even though the I2C device holds a reference on the parent device). To fix this set first the Peer Device Type to none which will remove the I2C device. Note that atm, inconsistently, the parent of the I2C device is initially set to the DRM kdev and after a Connection Status Notification the parent may be reset to be the connector's kdev. This problem is addressed by the next patch.

Some TypeC -> native DP adapters, at least the Club 3D CAC-1557 adapter, incorrectly filter out HPD short pulses with a duration less than ~540 usec, leading to MST probe failures. According to the DP Standard 2.0 section 5.1.4: - DP sinks should generate short pulses in the 500 usec -> 1 msec range - DP sources should detect short pulses in the 250 usec -> 2 msec range According to the DP Alt Mode on TypeC Standard section 3.9.2, adapters should detect and forward short pulses according to how sources should detect them as specified in the DP Standard (250 usec -> 2 msec). Based on the above filtering out short pulses with a duration less than 540 usec is incorrect. To make such adapters work add support for a driver polling on MST inerrupt flags, and wire this up in the i915 driver. The sink can clear an interrupt it raised after 110 msec if the source doesn't respond, so use a 50 msec poll period to avoid missing an interrupt. Polling of the MST interrupt flags is explicitly allowed by the DP Standard. This fixes MST probe failures I saw using this adapter and a DELL U2515H monitor. v2: - Fix the wait event timeout for the no-poll case. v3 (Ville): - Fix the short pulse duration limits in the commit log prescribed by the DP Standard. - Add code comment explaining why/how polling is used. - Factor out a helper to schedule the port's hpd irq handler and move it to the rest of hotplug handlers. - Document the new MST callback. - s/update_hpd_irq_state/poll_hpd_irq/ Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

So far the plane creation was done when each CRTC was bound, and those planes were only tied to the CRTC that was registering them. This causes two main issues: - The planes in the vc4 hardware are actually not tied to any CRTC, but can be used with every combination - More importantly, so far, we allocate 10 planes per CRTC, with 3 CRTCs. However, the next generation of hardware will have 5 CRTCs, putting us well above the maximum of 32 planes currently allowed by DRM. This patch is the first one in a series of patches that will take down both of these issues so that we can support the next generation of hardware while keeping a good amount of planes. We start by changing the way the planes are registered to first registering the primary planes for each CRTC in the CRTC bind function as we used to, but moving the overlay and cursor creation to the main driver bind function, after all the CRTCs have been bound, and make the planes associated to all CRTCs. This will slightly change the ID order of the planes, since the primary planes of all CRTCs will be first, and then a pattern of 8 overlays, 1 cursor plane for each CRTC. This shouldn't cause any trouble since the ordering between the planes is preserved though. Reviewed-by:

The planes so far were created as part of the CRTC binding code with each planes created associated only to one CRTC. However, the hardware in the vc4 doesn't really have such constraint and can be used with any CRTC. In order to rework this, let's first move the overlay and cursor planes creation to a function of its own. Reviewed-by:

vc4_drv.h doesn't have any include guards which prevents it from being included twice. Let's add them. Reviewed-by:

While the device tree and the driver expected a clock-names property, it wasn't explicitly documented in the previous binding. The documented order was wrong too, so make sure clock-names is there and in the proper order. Cc: devicetree@vger.kernel.org Reviewed-by:

The BCM283x SoCs have a display pipeline composed of several controllers with device tree bindings that are supported by Linux. Now that we have the DT validation in place, let's split into separate files and convert the device tree bindings for those controllers to schemas. This is just a 1:1 conversion though, and some bindings were incomplete so it results in example validation warnings that are going to be addressed in the following patches. Acked-by:

The udl driver contains an implementation of GEM vmap and mmap operations that is identical to the common SHMEM helper; except that udl's code uses cached pages by default. Convert udl to regular SHMEM helper functions. There's no reason to have udl behave differently from all other SHMEM drivers. The udl driver uses the SHMEM helper to enable caching. v3: * rebased onto Daniel's shmem untangle series v2: * implement .gem_create_object with SHMEM helper Signed-off-by:
