[PATCH v2 00/41] drm/display: bridge-connector: attach encoder to the connector

[PATCH v2 00/41] drm/display: bridge-connector: attach encoder to the connector

[Luca Ceresoli]

This series simplifies using the bridge-connector by removing the need to
attach the newly created connector to the encoder.

== Series description

Currently all users of the bridge-connector must call
drm_connector_attach_encoder() immediately after a successful
drm_bridge_connector_init().

This is an unnecessary burden for users. Move the call to the end of
drm_bridge_connector_init() so all callers can be simplified.

 * Patch 1 adds a drm_connector_attach_encoder() call at the end of
   drm_bridge_connector_init()
 * The other patches remove drm_connector_attach_encoder() after all
   drm_bridge_connector_init() calls, ordered from the simplest ones
   (only the last one is somewhat non-obvious)

The Cc list is huge due to the many drivers touched. I sent v1 to a reduced
Cc list to ensure there is an agreement about the overall idea. That seems
to be the case, so now it's time to copy all drivers maintainers.

It would be nice to apply all of this series at once to avoid duplicated
calls to drm_connector_attach_encoder() in the interim. That would be
harmless beacuse drm_connector_attach_encoder() is idempotent, but
unpleasant.

== Additional rationale (for the curious)

Besides making the usage of the bridge-connector a bit simpler, this series
is in preparation for DRM bridge hotplug. Here's why, feel free to skip if
you don't care.

The old bridge hotplug proposals I have sent in the past [1] were based on
a hotplug-bridge driver to sit between the last fixed bridge and the first
hotplugged bridge. Discussion with the community led to the need of
removing the hotplug-bridge and let common DRM code handle hotplug. The
common place of code that appears the most suitable for hotplug handling is
the bridge-connector, which is by now the recommended way to handle
connector instantiation after a bridge chain.

So I'm in the process of extending the bridge-connector to be the central
point to handle bridge hotplug. Turns out the need to call
drm_connector_attach_encoder() after drm_bridge_connector_init() has
returned is adding big headaches to such work. So I'm send this long but
simple series to both simplify bridge-connector usage and remove one
obstacle from the bridge hotplug work. This series is relevant by itself
anyway.

== Grand plan

This is part of the work to support hotplug of DRM bridges. The grand plan
was discussed in [0].

Here's the work breakdown (➜ marks the current series):

 1. … add refcounting to DRM bridges struct drm_bridge,
      based on devm_drm_bridge_alloc()
    A. ✔ add new alloc API and refcounting (v6.16)
    B. ✔ convert all bridge drivers to new API (v6.17)
    C. ✔ kunit tests (v6.17)
    D. ✔ add get/put to drm_bridge_add/remove() + attach/detach()
         and warn on old allocation pattern (v6.17)
    E. … add get/put on drm_bridge accessors
       1. ✔ drm_bridge_chain_get_first_bridge(), add cleanup action (v6.18)
       2. ✔ drm_bridge_get_prev_bridge() (v6.18)
       3. ✔ drm_bridge_get_next_bridge() (v6.19)
       4. ✔ drm_for_each_bridge_in_chain() (v6.19)
       5. ✔ drm_bridge_connector_init (v6.19)
       6. ✔ protect encoder bridge chain with a mutex (v7.2)
       7. … of_drm_find_bridge
          a. ✔ add of_drm_get_bridge() (v7.0),
	       convert basic direct users (v7.0-v7.1)
	  b. ✔ convert direct of_drm_get_bridge() users, part 2 (v7.0)
	  c. ✔ convert direct of_drm_get_bridge() users, part 3 (v7.0)
	  d. ✔ convert direct of_drm_get_bridge() users, part 4 (v7.1-v7.2)
	  e. … convert bridge-only drm_of_find_panel_or_bridge() users
       8. drm_of_find_panel_or_bridge, *_of_get_bridge
       9. ✔ enforce drm_bridge_add before drm_bridge_attach (v6.19)
    F. ✔ debugfs improvements
       1. ✔ add top-level 'bridges' file (v6.16)
       2. ✔ show refcount and list lingering bridges (v6.19)
 2. … handle gracefully atomic updates during bridge removal
    A. ✔ Add drm_bridge_enter/exit() to protect device resources (v7.0)
    B. … protect private_obj removal from list
    C. ✔ Add drm_bridge_clear_and_put() (v7.1)
 3. … DSI host-device driver interaction
 4. ✔ removing the need for the "always-disconnected" connector
 5. ✔ Migrate i.MX LCDIF driver to bridge-connector (v7.2)
 6. ➜ DRM bridge hotplug
    A. ➜ Bridge hotplug management in the DRM core
       1. ➜ bridge-connector: attach encoder to the connector

[PATCH v2 01/41] drm/display: bridge-connector: attach the encoder to the created connector

[Luca Ceresoli]

Currently all users of the bridge-connector must call
drm_connector_attach_encoder() immediately after a successful
drm_bridge_connector_init().

This is an unnecessary burden for users. Move the call to the end of
drm_bridge_connector_init() so all callers can be simplified.

Update documentation accordingly, rewording a bit the whole paragraph which
would otherwise become poorly readable due to the growing list of actions.

Due to the long Cc list, when sending the series with b4 I hit the mail
provider limit, so patches after 34 were not sent.

I then sent them manually using the good old git format-patch/send-email,
but in the process I missed the v2 (heh, b4 is great at automating
that!). So patch 35 got sent without v2, and then I resent it and the
following ones with the v2 marker.

Sorry about the noise!

I think with Dmitry's all-series R-by this whole series can be applied at
once (I'll wait ~1 week before applying, in case of more comments). This
will avoid more iterations spamming lots of people.

Luca

[PATCH v2 41/41] drm: renesas: shmobile: remove now-redundant call to drm_connector_attach_encoder()

[Luca Ceresoli]

shmob_drm_connector_create() can init the connector in two ways, based on
the 'if (sdev->pdata)':

 1. manually in shmob_drm_connector_create(), or
 2. delegating to drm_bridge_connector_init()

Whichever branch is taken, drm_connector_attach_encoder() is called
immediately after to attach the connector to the encoder.

Now drm_bridge_connector_init() calls drm_connector_attach_encoder() on the
connector so it is not needed anymore in case 2 and should be removed, but
it is still needed in case 1. Move drm_connector_attach_encoder() from the
common path to inside shmob_drm_connector_create() in order to get back to
a single drm_connector_attach_encoder() in both cases.
