2020-02-26drm/omap: Switch the HDMI and VENC outputs to drm_bridgeLaurent Pinchart1-217/+0
The TPD12S015, OPA362 and analog and HDMI connectors are now supported by DRM bridge drivers, and the omapdrm HDMI and VENC outputs can be handled through the drm_bridge API. Switch the outputs to drm_bridge by making the next bridge mandatory and removing the related omapdrm-specific display drivers.

2020-02-26drm/omap: dss: Fix output next device lookup in DTLaurent Pinchart1-1/+1
The DSS core looks up the next device connected to an output by traversing the OF graph. It currently hardcodes the local port number to 0, which breaks any output with a different port number (SDI on OMAP3 and any DPI output but the first one). Fix this by repurposing the currently unused of_ports bitmask in omap_dss_device with an of_port output port number, and use it to traverse the OF graph.

2019-03-18drm/omap: Merge omap_dss_device type and output_type fieldsLaurent Pinchart1-1/+0
The omap_dss_device type and output_type fields differ mostly for historical reasons. The output_type field is required for all devices but the display at the end of the pipeline, and must be set to OMAP_DISPLAY_TYPE_NONE for the latter. The type field is required for all devices but the internal encoder, for which it is ignored. The only reason why the output_type field must be set to OMAP_DISPLAY_TYPE_NONE for the display at the end of the pipeline is to identify omap_dss_device instances corresponding to displays. This is not documented and confusing. Clean the code by adding a new display field to the omap_dss_device structure to identify displays, and merge the type and output_type fields.

2019-03-18drm/omap: Reverse direction of the DSS device enable/disable operationsLaurent Pinchart1-35/+0
The omapdrm and omapdss drivers are architectured based on display pipelines made of multiple components handled from sink (display) to source (DSS output). This is incompatible with the DRM bridge and panel APIs that handle components from source to sink. Reconcile the omapdrm and omapdss drivers with the DRM bridge and panel model by reversing the direction of the DSS device .enable() and .disable() operations. This completes the move to the DRM bridge model, with the notable exception of the DSI pipelines that will require more work. We also adapt the omapdss shutdown handler dss_shutdown() to shut down all active pipelines starting from the pipeline output device instead of the display device. As a consequence the for_each_dss_display() macro isn't used and can be removed, and the omapdss_device_get_next() function underlying the macro can be simplified to search for output devices only.

2019-03-18drm/omap: Remove connection checks from display .enable() and .remove()Laurent Pinchart1-4/+0
The displays (connectors, panels and encoders) return an error from their .enable() handler when the dss device is not connected. They also disconnect the dss device explicitly from their .remove() handler if it is still connected. Those safety checks are not needed: - The .enable() handler is called from code paths that access the dss devices chain from the display device, which is set to NULL when the device isn't connected. - The .remove() handler can only be called when unloading the module as the driver has the suppress_bind_attrs attribute set, and a reference to the module is taken when constructing the dss devices chain, so the module can only be unloaded when the dss device is disconnected. Remove the safety checks.

On HDMI outputs, CEC support requires notification of HPD signal deassertion. The HPD signal can be handled by various omap_dss_device instances in the pipeline, and all of them forward HPD events to the OMAP4 internal HDMI encoder.

2018-09-03drm/omap: Merge HPD enable operation with HPD callback registrationLaurent Pinchart1-22/+1
The omap_dss_device .enable_hpd() and .disable_hpd() are used to enable and disable hot-plug detection at omapdrm probe and remove time. This is required to avoid reporting hot-plug detection events before the DRM infrastructure is ready to accept them, as that could result in crashes or other malfunction. Hot-plug event reporting is conditioned by both HPD being enabled through the .enable_hpd() operation and by the HPD callback being registered though the .register_hpd_cb() operation. We thus don't need a separate enable operation if we can guarantee that callbacks won't be registered too early. HPD callbacks are registered at connector initialization time, which is too early to start reporting HPD events. There's however nothing blocking a move of callback registration to a later time when the omapdrm driver calls the HPD enable operations. Do so, and remove the HPD enable operation completely from omap_dss_device drivers.

2018-09-03drm/omap: Move most omap_dss_driver operations to omap_dss_device_opsLaurent Pinchart1-7/+7
omap_dss_device instances have two ops structures, omap_dss_driver and omap_dss_device_ops. The former is used for devices at the end of the pipeline (a.k.a. display devices), and the latter for intermediate devices. Having two sets of operations isn't convenient as code that iterates over omap_dss_device instances need to take them both into account. There's currently a reasonably small amount of such code, but more will be introduced to move the driver away from recursive operations. To simplify current and future code, move all operations that are not specific to the display device to the omap_dss_device_ops.

The omapdss_of_find_source_for_first_ep() function locates the source corresponding to the first endpoint of the first port of a device node. We can easily extend it to locate sinks as well by passing the port number as a parameter. This will be useful to find sinks in encoders drivers. Extend the function and rename it to omapdss_of_find_connected_device() to reflect its new extended purpose. Additionally, it is useful to differentiate between failures to return the connected device because no link exists in the device tree for the requested port, or because the connected device as described in the device tree is invalid or not probed yet. Return NULL in the first case and an error code in the second case, and update the callers accordingly.

The omap_dss_device port_num field stores the DT port number associated with the device. The field is used in different ways depending on the device type: - For DPI outputs, the port number is used as an identifier of the DPI instance - For sources, the port number is used to look up the omap_dss_device by DT port node As omap_dss_device instances are only looked up as sources by sinks, setting the field to the number of the source port works for both use cases. However, to enable looking up sinks, we need to record all the ports associated with an omap_dss_device. Do so by turning the port_num field into an of_ports bitmask. For DPI outputs the port number is additionally stored in the dpi_data structure as the output ID.

Some panel/encoder/connector driver includes omap-panel-data.h but they do not need it. Remove the inclusion of video/omap-panel-data.h from these drivers. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com>
2016-03-03drm/omap: tpd12s015: CT_CP_HPD as optional gpioManisha Agrawal1-1/+1
tpd12s015 HW has LS_OE, CT_CP_HPD and HPD gpios. Out of these gpios, driver only handled LS_OE as optional. The CT_CP_HPD gpio should also be treated as optional gpio as it is just a power saving feature. Some boards hardwire this gpio to be always enable. In this patch, all access to CT_CP_HPD gpio is made optional.

All devices using tpd12s015 driver are doing DT boot. No need of further supporting the platform data. This patch removes support for platform data.

2015-12-29drm/omap: move omapdss & displays under omapdrmTomi Valkeinen1-0/+379
Now that omapfb has its own copy of omapdss and display drivers, we can move omapdss and display drivers which omapdrm uses to omapdrm's directory. We also need to change the main drm Makefile so that omapdrm directory is always entered, because omapdss has a file that can't be built as a module.
