Sam Ravnborg aa6c43644b drm/panel: drop drm_device from drm_panel
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)

Sam Ravnborg 0ce8ddd8e0 drm/panel: add drm_connector argument to get_modes()
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)

Laurent Pinchart 9a2654c0f6 drm/panel: Add and fill drm_panel type field
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.

Laurent Pinchart 6dbe0c4b0f drm/panel: Initialise panel dev and funcs through drm_panel_init()
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;
