Hello,
This patch series finishes the large omapdrm refactoring started in v4.17 to
transition from the omapdrm-specific encoder and panel drivers to drm_bridge
and drm_panel. While more changes will follow, the next patch series will
focus on the usage of the first drm_bridge driver (for the tftp410).
The series starts with a few miscalleanous cleanups (01/29 to 04/29) and then
reverses the direction of the DSS device .enable() and .disable() operations
(05/29 to 09/29). All DSS device operations now match the drm_bridge model.
After a bit of further cleanups (10/29 and 11/29), the next step is to move
from struct videomode to struct drm_display_mode in the encoder and panel
drivers (12/29 to 14/29). This allows the VENC encoder to report all supported
modes (PAL and NTSC), not just the active mode (15/29).
We then move to removing access to the component at the end of the pipeline,
as the bridge API doesn't give us easy access to it (patches 16/29 to 18/29).
The next three patches (19/29 to 21/29) remove the src field from the
omap_dss_device structure, again to align with drm_bridge.
Additional miscellaneous refactoring follows to simplify the code (22/29 to
24/29), and the next patch (25/29) replaces usage of struct videomode with
struct drm_display_mode for the .check_timings() and .set_timings()
operations. The VENC encoder can then use struct drm_display_mode internally
(26/29) and the DPI and SDI drivers can avoid storing the full mode
(27/29).
Finally patches 28/29 and 29/29 simplify and refactor the omapdrm
initialization sequence to prepare for drm_bridge usage.
With these changes in place, the next series will fix a few issues in the
tfp410 drm_bridge driver, add direct support for drm_bridge in omapdrm, and
remove the internal tfp410 and DVI connector drivers.

Instead of rolling out custom suspend/resume implementations based on
state information stored in the driver's data structures, use the atomic
suspend/resume helpers that rely on a DRM atomic state object.

All .enable() and .disable() handlers for panels and connectors share
common code that validates and updates the device's state. Move it to
common locations in the omap_encoder_enable() and omap_encoder_disable()
handlers.
The enabled check in the .disable() handler is left untouched, it will
be addressed separately.

From: Laurent Pinchart @ 2018-12-05 14:59 UTC (permalink / raw)
To: dri-devel; +Cc: Tomi Valkeinen
The internal encoders return an error from their .enable() handler when
their are not connected to a dss manager. As the flag used is set and
cleared in the connect and disconnect handlers, this effectively checks
whether the omap_dss_device is connected.
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, making it impossible to access the device in
that case.
The safety check is thus not needed, remove it.

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.

The displays (connectors, panels and encoders) bail out from their
.enable() and .disable() handlers if the dss device is already enabled
or disabled. Those safety checks are not needed when the functions are
called through the omapdss_device_ops, as the .enable() and .disable()
handlers are called from the DRM atomic helpers that already guarantee
that no double enabling or disabling can occur.
However, the handlers are also called directly from the .remove()
handler. While this shouldn't be needed either as the modules can't be
removed as long as the device is in use, it's still a good practice to
disable the device explicitly. There is currently a safety check in
.remove() in some drivers but not all of them.
Remove the safety checks from the .enable() and .disable() handlers, and
add missing ones in the .remove() handler.

From: Laurent Pinchart @ 2018-12-05 15:00 UTC (permalink / raw)
To: dri-devel; +Cc: Tomi Valkeinen
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.

The field is only used in a safety check during device

instead. Remove it and use src.

All the internal encoders share common init and cleanup code. Factor it
out to separate functions.

To: dri-devel; +Cc: Tomi Valkeinen
omap_dss_device operations expose fixed video timings through a
.get_timings() operation that return a single timing for the device. To
prepare for the move to drm_bridge, modify the API to instead add DRM
modes directly to the connector.
As this puts more burden on display devices, we also create a helper
function for panels to add a single DRM mode from the panel video
timings.

Now that the .get_modes() operations takes a drm_connector and fills it
with modes, it becomes easy to fill display information in the same
operation without requiring a separate .get_size() opearation.

Instead of manually iterating over the dss devices in the pipeline to
find the first one that implements the .get_modes() operation, add a new
operation flag for .get_modes() and use the omap_connector_find_device()
helper function to locate the right dss device.

The TV encoder supports both PAL and NTSC modes, but when queried for
the list of modes it supports, only the currently selected mode is
reported. Fix it and report the two modes unconditionally.

The display isn't used by the encoder implementation, don't pass it to
the initialization function and store it internally needlessly.

The DT bindings for the OMAP DSS allow assigning numerical IDs to
display outputs through display entries in the alias node. The driver
uses this information to sort pipelines according to the order specified
in DT, making it possible for a system to give a priority order to
outputs.
Retrieval of the alias ID is done when initializing display dss devices.
That code will be removed when moving to drm_bridge and drm_panel. Move
retrieval of the alias ID to display pipeline connection time and store
it in the pipeline structure instead to keep the feature.

Display pipelines based on drm_bridge are handled from the bridge
closest to the CRTC. To move to that model we thus need to transition
away from walking pipelines in the other direction, and from accessing
the device at the end of the pipeline when possible.
Remove most accesses to the display device from the omap_connector
implementation, and don't store it in the omap_connector structure.
- For debug messages we can simply use the connector name instead.
- For type checks we can use the drm_connector type.
- For operation lookup we can start at the other end of the pipeline and
locate the last matching device.
The display device is still passed to the connector init function in
order to find its type, which requires access to the end of the
pipeline.

The source pointer will be removed to the omap_dss_device structure.
Store it internally in the DSI panel driver data.

For HDMI pipelines, when the output gets disconnected the device
handling CEC needs to be notified. Instead of guessing which device that
would be (and sometimes getting it wrong), notify all devices in the
pipeline.

The field is only used to check whether the device is connected, and we
can do so by checking the dss field instead. Remove the src field.

The DISPC timings checks relate to the CRTC, but they're performed in
the encoder and connector .atomic_check() and .mode_valid() operations.
Move them to the CRTC .mode_valid() operation.

The mode setting handler of the VENC stores the video mode internally,
to then convert it to a configuration when programming the hardware. The
stored mode is otherwise unused. Cache the configuration directly
instead.

The encoder .atomic_check() and connector .mode_valid() operations both
walk through the dss devices in the pipeline to validate the mode.
Factor out the common code in a new omap_drm_connector_mode_fixup()
function.

The omap_dss_device .check_timings() and .set_timings() operations
operate on struct videomode, while the DRM API operates on struct
drm_display_mode. This forces conversion from to videomode in the
callers. While that's not a problem per se, it creates a difference with
the drm_bridge API.
Replace the videomode parameter to the .check_timings() and
.set_timings() operations with a drm_display_mode. This pushed the
conversion to videomode down to the DSS devices in some cases. If needed
they will be converted to operate on drm_display_mode natively.

Replace internal usage of struct videomode with struct drm_display_mode
in order to avoid converting needlessly between the data structures.

The DPI and SDI encoders store the full videomode upon mode set, to only
use the value of the pixel clock when enabling the encoder. This wastes
memory. Store the pixel clock value only.

Now that the direction of OF graph walk has been reversed, there's no
need to lookup devices by port as we have no sink device connected
through multiple sink ports. Simplify OF lookup of the DSS devices to
look them up by node only.

The omapdrm driver initialization procedure starts by connecting all
available pipelines, gathering related information (such as output and
display DSS devices, and DT aliases), sorting them by alias, and finally
creates all the DRM/KMS objects.
When using DRM bridges instead of DSS devices, we will need to attach to
the bridges before getting the aliases. As attaching to bridges requires
an encoder object, we have to reorganize the initialization sequence to
create encoders before getting aliases and sorting the pipelines.

This is a bit tricky to review. It would probably be easier to

This will explode if adjusted_mode is NULL?

From: Laurent Pinchart @ 2018-12-10 1:01 UTC (permalink / raw)
To: dri-devel; +Cc: Tomi Valkeinen
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.
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

Changes since v1:
- Shutdown pipelines starting at the output device

* [PATCH v1.1 04/29] drm/omap: Use atomic suspend/resume helpers

Instead of rolling out custom suspend/resume implementations based on
state information stored in the driver's data structures, use the atomic
suspend/resume helpers that rely on a DRM atomic state object.
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

Changes since v1:
- Use drm_mode_config_helper_suspend()

Correct, but this function should never (and is never as far as I can tell)
called with adjusted_mode equal to NULL.

I will instead remove the check in the previous patch where it was needlessly
introduced.

I agree that the connector changes are not very nicely formatted. I however
don't like splitting patches, especially when small, in such a way.
One issue preventing a better diff formatting is the change from int to enum
drm_mode_status for the omap_connector_mode_valid() function. Without that
change, the patch can be better formatted with
git diff --anchored="static int omap_connector_mode_valid"
I agree it's still not perfect.
If you think the above change is worth it I'll submit a split version,
otherwise I'll leave it as is.

The encoder .atomic_check() and connector .mode_valid() operations both
walk through the dss devices in the pipeline to validate the mode.
Factor out the common code in a new omap_drm_connector_mode_fixup()
function.

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.

I plan to test this series in combination with my DSI patches today
or tomorrow evening. If it works, probably the following should be
added to the patch description:
--------------------
As a side-effect this fixes DSI, which uses slightly different mode
configuration for the DSI encoder and the DISPC.
Fixes: 7c27fa57ef31 ("drm/omap: Call dispc timings check operation directly")

I merged this series with my remaining DSI command mode patches
(btw. this series does not apply cleanly to master due to a recent
patch from Tomi). Unfortunately this patch does not fix the issue.
After this patch the mgr_check_timings() call in omap_crtc_mode_valid()
will fail.
The good news: The Droid 4 display worked again after dropping the
mgr_check_timings call as a quick hack. So the other patches from
this set are
Tested-by: Sebastian Reichel <sebastian.reichel@collabora.com>
The problem is, that DISPC timings for DSI are not directly
calculated from mode. Instead DSI code does some modifications
before applying the DISPC settings.

I'll fix that, thank you for the notice.

Thank you for testing this.

I wonder what the best way to fix this would be. DSI isn't so special in this
regard, any encoder can modify modes, resulting in the CRTC outputting a mode
significantly different than the mode being displayed. This is handled by the
DRM helpers through the .mode_fixup() operations, which can mangle modes along
the pipeline.
At atomic commit time the atomic helpers call .mode_valid() first, followed by
.mode_fixup(). An easy fix would be to remove our .mode_valid() handlers
completely and perform both fixup and validation in the .mode_fixup()
handlers.
However, the .mode_valid() operations are also used in
drm_helper_probe_single_connector_modes(), where no mode fixup is performed.
We can't drop .mode_valid() for that code path (at least not as anything else
than a hack). Daniel, what's the expected way to handle this ?
