Use the common MIPI_DCS_GET_ERROR_COUNT_ON_DSI define instead of driver's own. Signed-off-by:

dss_mgr_ops was needed with the multi-module architecture, but is no longer needed. We can thus remove it and use direct calls. Signed-off-by:
-
Tomi Valkeinen authored
dispc_ops was created to help with the multi-module architecture and giving us the possibility of multiple dispc implementations. Neither of these is valid anymore, and we can remove dispc_ops and use direct calls to dispc. Signed-off-by:

dssdev->owner is set, but never used. We can drop the field. Signed-off-by:

The functions in display.c are not used, so drop the file. Signed-off-by:

At the moment we have three different modules: omapdss-base, omapdss, omapdrm. This setup is finally obsolete, as the last omapdrm specific panel has been converted to DRM panel. We can thus remove omapdss-base and omapdss, and just compile everything into omapdrm.ko. Signed-off-by:

The DSI command mode panel is no longer specific to OMAP and thus the config option has been renamed slightly. Signed-off-by:

Simplify DSI pin config, which always originates from DT nowadays. With the code being fully contained in the DSI encoder, we can drop the public structure. Since the function is no longer exposed, it now directly takes the private DSI data pointer. This drops a pointless conversion and means the pins can be configured earlier. Signed-off-by:
-
Sebastian Reichel authored
Move dsi_ops into the main structure, since all other ops are gone. Instead of checking the device type we can simply check if dsi_ops are set. Signed-off-by:
-
Sebastian Reichel authored
All displays are now using a drm_panel or a drm_bridge that models the connector instead of dssdev, so this field is always 0 and can be dropped. Signed-off-by:
-
Sebastian Reichel authored
The omapdss device's ops_flags field is no longer used and can be dropped. Signed-off-by:
-
Sebastian Reichel authored
Since all encoders and panels are using the bridge API now, we next pointer is no longer useful and can be dropped. Signed-off-by:
-
Sebastian Reichel authored
We no longer need to check for the DSS API, since all encoders, panels and connectors have been converted to the bridge API. Signed-off-by:
-
Sebastian Reichel authored
Remove unused code. Connectors are now created via drm_bridge_connector_init() and no longer OMAP specific. Signed-off-by:
-
Sebastian Reichel authored
All DSS devices have been converted to bridge API, so the device operations are always NULL. This removes the device ops function pointers and all code using it. Signed-off-by:
-
Sebastian Reichel authored
In order to integrate with a chain of drm_bridge, the internal DSI output has to expose its operations through the drm_bridge API. Register a bridge at initialisation time to do so and remove the omap_dss_device operations that are now unused. Signed-off-by:
-
Sebastian Reichel authored
The panel driver is no longer using any OMAP specific APIs, so let's move it into the generic panel directory. Signed-off-by:
-
Sebastian Reichel authored
We can simply provide the device to the omapdrm driver via pdata. omapdss_is_initialized() is no longer required (even before this patch), since omapdrm device is only registered after the pointer is initialized. Signed-off-by:
-
Sebastian Reichel authored
Do not try to reset the panel after DSI has been detached, since the DSI clocks may have been disabled at this point. The panel will be disabled and unprepared before being removed and a reset will be done when being probed again. Signed-off-by:

Sebastian Reichel authored
Now, that the driver implements the common DRM panel API the unbind no longer needs to be suppressed. Signed-off-by:
-
Sebastian Reichel authored
Use DEVICE_ATTR_RO helper instead of plain DEVICE_ATTR, which makes the code a bit shorter and easier to read. Signed-off-by:
-
Sebastian Reichel authored
Implement check timings, which will check if it's possible to configure the clocks for the provided mode using the same code as the set_config() hook. Signed-off-by:
-
Sebastian Reichel authored
The table of compatible values needed to be prefixed with "omapdss," is empty, so all of this code is doing nothing now. Let's drop it. Signed-off-by:
-
Sebastian Reichel authored
This converts the DSI module to expect common drm_panel display drivers instead of dssdev based ones. Signed-off-by:
-
Sebastian Reichel authored
Due to previous changes the DSI encoder gets the capabilities via DSI client's mode_flags and no longer needs the omapdss specific caps. The core code now checks if the DSI encoder is actually configured into command mode instead of just checking the panel capabilities. Signed-off-by:

Complete the direction reversal of the DSS device enable/disable operations started by commit 19b4200d ("drm/omap: Reverse direction of the DSS device enable/disable operations"). This effectively drops the requirement of calling DSS specific code from the DSI panel driver moving it a bit further to a standard drm_panel driver. Signed-off-by:
-
Sebastian Reichel authored
This moves the panel refresh/update function from the panel driver into the DSI host driver to prepare for common drm_panel support. Signed-off-by:
-
Sebastian Reichel authored
Move ULPS handling into the DSI host controller, so that we no longer need a custom API for the DSI client. Note that for now ULPS is always disabled. Signed-off-by:
-
Sebastian Reichel authored
Create a custom function pointer for ULPS and use it instead of reusing disable/enable functions for ULPS mode switch. This allows us to use the common disable/enable functions pointers for DSI. Signed-off-by:
-
Sebastian Reichel authored
This moves the bus locking into the host driver and unexports the custom API in preparation for drm_panel support. Signed-off-by:
-
Sebastian Reichel authored
Instead of using the custom enable_te() API, this automatically enables/disables TE core support when a matching packet is sent to the panel. Signed-off-by:
-
Sebastian Reichel authored
In preparation for removing custom DSS calls from the DSI panel driver, this moves support for external tearing event GPIOs into the DSI host driver. This way tearing events are always handled in the core resulting in simplification of the panel drivers. The TE GPIO acquisition follows works in the same way as the exynos DSI implementation.

Integrate low-power / high-speed bus switching into transfer function and drop the omapdrm specific enable_hs() callback. Signed-off-by:

Sebastian Reichel authored
Use bulk regulator API to simplify the code. This also switches from _optional variant to normal variant, which will provide a dummy regulator (i.e. if some always-enabled regulator is not described in DT). Signed-off-by:

In order to reduce the amount of custom functionality, this moves handling of pixel format and DSI mode from set_config() to dsi attach. Signed-off-by:

Sebastian Reichel authored
The DSI sync() function only locks the bus and then releases it again. Currently the only invocation is directly before update(), which locks the bus anyways. Signed-off-by:
