Merge v5.4-rc4 into drm-next

2019-10-23T10:10:05+00:00

Thierry needs fd70c7755bf0 ("drm/bridge: tc358767: fix max_tu_symbol
value") to be able to merge his dp_link patch series.

Some adjacent changes conflicts, plus some clashes in i915 due to
cherry-picking and git trying to be helpful and leaving both versions
in.

drm/panel: tpo-td043mtea1: Fix SPI alias

2019-10-08T05:02:20+00:00

The panel-tpo-td043mtea1 driver incorrectly includes the OF vendor
prefix in its SPI alias. Fix it, and move the manual alias to an SPI
module device table.

drm: panel-lvds: Potential Oops in probe error handling

2019-09-21T18:48:09+00:00

The "lvds->backlight" pointer could be NULL in situations where
of_parse_phandle() returns NULL.  This code is cleaner if we use the
managed devm_of_find_backlight() so the clean up is automatic.

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;
)
