This rename is done so that the driver matches the name of the display controller and in preparation for adding support for more panels to the driver. This is just a basic file rename, with no code changes. 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. Note: DRM_BUS_FLAG_PIXDATA_SAMPLE_POSEDGE = DRM_BUS_FLAG_PIXDATA_NEGEDGE DRM_BUS_FLAG_PIXDATA_SAMPLE_NEGEDGE = DRM_BUS_FLAG_PIXDATA_POSEDGE Signed-off-by:

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:

Only the MEDIA_BUS_FMT_RGB666_1X7X3_SPWG, MEDIA_BUS_FMT_RGB888_1X7X4_SPWG and MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA bus formats are valid for LVDS panels.

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:

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:

The helper uses the MIPI_DCS_SET_TEAR_SCANLINE, although it's currently using the generic write. This does not look right. Perhaps some platforms don't distinguish between the two writers?

A few of the new panels create a local macro wrapping around mipi_dsi_dcs_write. At the same time, they don't really care about the command/payload split. mipi_dsi_dcs_write does a kmalloc/memcpy/kfree for payload > 7 bytes. Avoid that all together by using the _buffer function. Aside: panel-xinpeng-xpp055c272.c calls its wrapper "generic" although it should be "dcs". But that for another day/patch.

Currently the function heap allocates when we have any payload. Where in many case the payload is 1 byte - ouch. >From casual observation, vast majority of the payloads are smaller than 8 bytes - so use a stack array tx[8] to avoid the senseless kmalloc and kfree dance.

ti-sn65dsi86 bridge is enumerated as a runtime device. When suspend is triggered, PM core adds a refcount on all the devices and calls device suspend, since usage count is already incremented, runtime suspend will not be called and it kept the bridge regulators and gpios ON which resulted in platform not entering into XO shutdown. Add changes to force suspend on the runtime device during pm sleep. Signed-off-by:
