This reverts commit 5de376bb. This change breaks synchronization of a timeline. dma_fence_chain_find_seqno() might be a bit of a confusing name but this function is not trying to find a particular seqno, is supposed to give a fence to wait on for a particular point in the timeline. In a timeline, a particular value is reached when all the points up to and including that value have signaled. Signed-off-by:

The reset pin is inverted, so if we don't assert reset, the actual gpio will be high and may keep driving the IO port of the panel. Signed-off-by:

Replace all uses of the legacy drm_bus_flags with their relevant _SAMPLE_ variant. This is a 1:1 replacement, no effort was made to validate the actual bus flags for the panels.

When graph isn't defined in a device-tree, the of_graph_get_remote_node() prints a noisy error message, telling that port node is not found. This is undesirable behaviour in our case because absence of a panel/bridge graph is a valid case. Let's check the graph's presence in a device-tree before proceeding with parsing of the graph.

In some cases it's very useful to silently check whether port node exists at all in a device-tree before proceeding with parsing the graph. The DRM bridges code is one example of such case where absence of a graph in a device-tree is a legit condition. This patch adds of_graph_is_present() which returns true if given device-tree node contains OF graph port. Reviewed-by:

The DRM bus flags reporting on which clock edge the pixel data and sync signals are sampled or driven don't make sense for LVDS panels, as the bus then uses sub-clock timings to send data. Drop those flags and add a warning in the probe function to make sure the mistake won't be repeated. Signed-off-by:

The Satoz SAT050AT40H12R2 panel is an LVDS panel, the MEDIA_BUS_FMT_RGB888_1X24 bus format is thus incorrect. Set it to the correct value MEDIA_BUS_FMT_RGB888_1X7X4_SPWG. Signed-off-by:

Added epoch counter checking to intel_encoder_hotplug in order to be able process all the connector changes, besides connection status. Also now any change in connector would result in epoch counter change, so no multiple checks are needed. v2: Renamed change counter to epoch counter. Fixed type name. v3: Fixed rebase conflict v4: Remove duplicate drm_edid_equal checks from hdmi and dp, lets use only once edid property is getting updated and increment epoch counter from there. Also lets now call drm_connector_update_edid_property right after we get edid always to make sure there is a unified way to handle edid change, without having to change tons of source code as currently drm_connector_update_edid_property is called only in certain cases like reprobing and not right after edid is actually updated. v5: Fixed const modifiers, removed blank line v6: Removed drm specific part from this patch, leaving only i915 specific changes here.

This counter will be used by drm_helper_probe_detect caller to determine if anything had changed(including edid, connection status and etc). Hardware specific driver detect hooks are responsible for updating this counter when some change is detected to notify the drm part, which can trigger for example hotplug event. Also now call drm_connector_update_edid_property right after we get edid always to make sure there is a unified way to handle edid change, without having to change tons of source code as currently drm_connector_update_edid_property is called only in certain cases like reprobing and not right after edid is actually updated. v2: Added documentation for the new counter.

The example used in the DPI binding before the conversion to YAML had a simple-panel example that got carried over to the YAML binding. However, that example doesn't match the simple-panel binding and results in validation errors. Since it's only marginally helpful, let's remove that part of the example entirely.

All the functionality in this driver has been reimplemented in the new DRM driver in drivers/gpu/drm/pl111/* and all the boards using it have been migrated to use the DRM driver with all configuration coming from the device tree. I started the work to migrate the CLCD driver to DRM in april 2017 and it took a little more than 3 years to do this properly without leaving any platforms behind. Reviewed-by:
