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:

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:

The panel driver is no longer using any OMAP specific APIs, so let's move it into the generic panel directory. Signed-off-by:

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:

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:

Now, that the driver implements the common DRM panel API the unbind no longer needs to be suppressed. Signed-off-by:

Use DEVICE_ATTR_RO helper instead of plain DEVICE_ATTR, which makes the code a bit shorter and easier to read. Signed-off-by:

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:

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:

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:

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:

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:

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:

Drop custom request_vc/release_vc callbacks by using the generic mipi_dsi_attach/mipi_dsi_detach functions. To use mipi_dsi_attach() we need to fill in the mipi_dsi_device fields, and some of these fields overlap with the fields in omap_dss_dsi_config. In later patches the latter will get dropped.

After converting the driver to mipi_dsi_device we can use the generic message helpers to simplify the driver a lot. Signed-off-by:
-
Sebastian Reichel authored
This moves from custom platform driver infrastructure to mipi_dsi_host and mipi_dsi_device. Note, that this is a graduate step and the driver only uses the devices types and transfer function, but not yet the new device binding style or drm_panel. Signed-off-by:

Simplify the DSI encoder by using mipi_dsi_msg for dsi_vc_send_long and dsi_vc_send_short. Further improvements require cleaning up the channel allocation code first. Signed-off-by:

This drops the virtual channel logic. Afterwards DSI clients request their channel number and get the virtual channel with the same number or -EBUSY if already in use. The change here is not strictly speaking correct, as it combines the VC (DSI's "configuration block") and virtual channel ID (the ID sent in the DSI packets). But as we currently only support a single DSI command mode panel, this works fine: we always use VC0, and VC ID 0. This needs more work to support video mode panels, but that can be done after moving to DRM bridge and panel model, after which we can do that work with the proper APIs. Signed-off-by:

After converting all DSI drivers, unexport the specific transfer functions. Signed-off-by:
-
Sebastian Reichel authored
This converts the panel-dsi-cm driver to use the transfer API instead of specific functions, so that the specific functions can be unexported and squashed into the generic transfer function. Signed-off-by:
-
Sebastian Reichel authored
This prepares the driver for becoming a mipi_dsi_host implementation, which provides a generic transfer function instead of all kind of different read/write functions. The implementation will become more elegant after unexporting the specific functions in the following patches. Signed-off-by:

The write buffers are not modified, so they can be constant. Signed-off-by:

This replaces OMAP specific enum for pixel format with common implementation. Signed-off-by:

The panel-dsi-cm's ddata->pin_config is always NULL, so this callback is never called. Instead the DSI encoder gets the pin configuration directly from DT. Signed-off-by:
