drm/panel: drop drm_device from drm_panel

2019-12-09T21:57:26+00:00

The panel drivers used drm_panel.drm for two purposes:
1) Argument to drm_mode_duplicate()
2) drm->dev was used in error messages

The first usage is replaced with drm_connector.dev
- drm_connector is already connected to a drm_device
  and we have a valid connector

The second usage is replaced with drm_panel.dev
- this makes drivers more consistent in their dev argument
  used for dev_err() and friends

With these replacements there are no more uses of drm_panel.drm,
so it is removed from struct drm_panel.
With this change drm_panel_attach() and drm_panel_detach()
no longer have any use as they are empty functions.

v2:
  - editorial correction in changelog (Laurent)

drm/panel: add drm_connector argument to get_modes()

2019-12-09T21:57:26+00:00

Today the bridge creates the drm_connector, but that is planned
to be moved to the display drivers.
To facilitate this, update drm_panel_funcs.get_modes() to
take drm_connector as an argument.
All panel drivers implementing get_modes() are updated.

v2:
  - drop accidental change (Laurent)
  - update docs for get_modes (Laurent)

drm/panel: simple: use drm_panel backlight support

Use drm_panel infrastructure for backlight.
Replace direct calls with drm_panel_*() calls
to utilize the drm_panel support.

drm/panel: simple: Add Logic PD Type 28 display support

2019-11-30T22:03:24+00:00

Previously, there was an omap panel-dpi driver that would
read generic timings from the device tree and set the display
timing accordingly.  This driver was removed so the screen
no longer functions.  This patch modifies the panel-simple
file to setup the timings to the same values previously used.

drm/panel: Add and fill drm_panel type field

2019-09-08T17:04:01+00:00

Add a type field to the drm_panel structure to report the panel type,
using DRM_MODE_CONNECTOR_* macros (the values that make sense are LVDS,
eDP, DSI and DPI). This will be used to initialise the corresponding
connector type.

Update all panel drivers accordingly. The panel-simple driver only
specifies the type for the known to be LVDS panels, while all other
panels are left as unknown and will be converted on a case-by-case
basis as they all need to be carefully reviewed.

drm/panel: Initialise panel dev and funcs through drm_panel_init()

2019-08-24T08:42:48+00:00

Instead of requiring all drivers to set the dev and funcs fields of
drm_panel manually after calling drm_panel_init(), pass the data as
arguments to the function. This simplifies the panel drivers, and will
help future refactoring when adding new arguments to drm_panel_init().

The panel drivers have been updated with the following Coccinelle
semantic patch, with manual inspection to verify that no call to
drm_panel_init() with a single argument still exists.

@@
expression panel;
expression device;
identifier ops;
@@
 drm_panel_init(&panel
+	, device, &ops
 );
 ...
(
-panel.dev = device;
-panel.funcs = &ops;
|
-panel.funcs = &ops;
-panel.dev = device;
)
