[PATCH v3 00/35] drm/bridge: Consolidate initialization

[PATCH v3 00/35] drm/bridge: Consolidate initialization

[Mihail Atanassov]

Hi all,

Version 3 of my drm_bridge_init() series here. The biggest change from
the previous version is the removal of drm_bridge->dev (1/35) and the
removal of ->driver_private (2-7/35). The rest of the patches are mostly
the same, save for dropping the driver_private argument from
drm_bridge_init().

v3:
 - remove drm_bridge->dev (Thomas)
 - convert ->driver_private users to container_of() (Laurent)
 - remove drm_bridge->driver_private (Laurent)
 - remove driver_private argument from drm_bridge_init() (Laurent)
 - clean up the wording on some comments (Laurent)
 - pass the correct struct device to drm_bridge_init in analogix
   (Laurent)
 - I've kept the rcar-du patches separate but changed their order; this
   should make it easier to take only one part of the series if needed

v2:
 - expanded commit messages and added some extra bridge-related
   documentation (Daniel)
 - dropped v1 patches 29 and 30: 29 needs more work, and 30 depends on
   it
 - added all remaining drm_bridge implementers, found by searching for
   drm_bridge_funcs which is mandatory for any bridge; new uses in
   patches 3, 27, and 28 (Sam)
 - due to the above, I've decided to squash all analogix changes into
   one patch

[PATCH v3 01/35] drm: Remove drm_bridge->dev

[Mihail Atanassov]

As suggested in [1], the 'dev' field is a bit repetitive, since it 1:1
follows the setting and NULLing of the 'encoder' field. Therefore, use
drm_bridge->encoder->dev in place of drm_bridge->dev.

[1] https://patchwork.freedesktop.org/patch/343824/

v3:
 - resend as part of drm_bridge_init() series
v2:
 - fix checkpatch complaint about unnecessary parentheses in
 drm_bridge.c

[PATCH v3 01/35] drm: Remove drm_bridge->dev

[Mihail Atanassov]

As suggested in [1], the 'dev' field is a bit repetitive, since it 1:1
follows the setting and NULLing of the 'encoder' field. Therefore, use
drm_bridge->encoder->dev in place of drm_bridge->dev.

[1] https://patchwork.freedesktop.org/patch/343824/

v3:
 - resend as part of drm_bridge_init() series
v2:
 - fix checkpatch complaint about unnecessary parentheses in
 drm_bridge.c

[PATCH v3 03/35] drm/bridge/synopsys: Stop using drm_bridge->driver_private

[Mihail Atanassov]

dw_hdmi: The drm_bridge struct is already embedded, so use
a container_of wrapper to access it.

dw-mipi-dsi: The field is unused, remove it.

safe to apply.

[PATCH v3 07/35] drm/sti: Stop using drm_bridge->driver_private

[Mihail Atanassov]

Instead, embed the drm_bridge structure in the originally-pointed-to
struct and use a container_of wrapper to access it.

[PATCH v3 09/35] drm: Introduce drm_bridge_init()

[Mihail Atanassov]

A simple convenience function to initialize the struct drm_bridge. The
goal is to standardize initialization for any bridge registered with
drm_bridge_add() so that we can later add device links for consumers of
those bridges.

v3:
 - drop driver_private parameter (Laurent)
 - spelling & style updates to docs (Laurent)
 - don't set drm_bridge->dev (field removed)
v2:
 - s/WARN_ON(!funcs)/WARN_ON(!funcs || !dev)/ as suggested by Daniel
 - expand on some kerneldoc comments as suggested by Daniel
 - update commit message as suggested by Daniel

[PATCH v3 09/35] drm: Introduce drm_bridge_init()

[Mihail Atanassov]

A simple convenience function to initialize the struct drm_bridge. The
goal is to standardize initialization for any bridge registered with
drm_bridge_add() so that we can later add device links for consumers of
those bridges.

v3:
 - drop driver_private parameter (Laurent)
 - spelling & style updates to docs (Laurent)
 - don't set drm_bridge->dev (field removed)
v2:
 - s/WARN_ON(!funcs)/WARN_ON(!funcs || !dev)/ as suggested by Daniel
 - expand on some kerneldoc comments as suggested by Daniel
 - update commit message as suggested by Daniel

No functional change.

The setting of bridge->of_node by drm_bridge_init() in
analogix_dp_core.c is safe, since ->of_node isn't used directly and the
bridge isn't published with drm_bridge_add().

[PATCH v3 35/35] drm/msm: Use drm_bridge_init()

[Mihail Atanassov]

No functional change: drm_bridge_init() sets bridge->of_node, but that's
not used by msm anywhere, and the bridges aren't published with
drm_bridge_add() for it to matter.

v3:
 - drop driver_private argument (Laurent)

[PATCH v3 35/35] drm/msm: Use drm_bridge_init()

[Mihail Atanassov]

No functional change: drm_bridge_init() sets bridge->of_node, but that's
not used by msm anywhere, and the bridges aren't published with
drm_bridge_add() for it to matter.

v3:
 - drop driver_private argument (Laurent)

[PATCH v3 RESEND 01/35] drm: Remove drm_bridge->dev

[Mihail Atanassov]

As suggested in [1], the 'dev' field is a bit repetitive, since it 1:1
follows the setting and NULLing of the 'encoder' field. Therefore, use
drm_bridge->encoder->dev in place of drm_bridge->dev.

[1] https://patchwork.freedesktop.org/patch/343824/

v3:
 - resend as part of drm_bridge_init() series
v2:
 - fix checkpatch complaint about unnecessary parentheses in
 drm_bridge.c

[PATCH v3 RESEND 01/35] drm: Remove drm_bridge->dev

[Mihail Atanassov]

As suggested in [1], the 'dev' field is a bit repetitive, since it 1:1
follows the setting and NULLing of the 'encoder' field. Therefore, use
drm_bridge->encoder->dev in place of drm_bridge->dev.

[1] https://patchwork.freedesktop.org/patch/343824/

v3:
 - resend as part of drm_bridge_init() series
v2:
 - fix checkpatch complaint about unnecessary parentheses in
 drm_bridge.c
