Revert "drm/bridge: Patch atomic hooks to take a drm_bridge_state"

2020-01-07T23:34:28+00:00

This reverts commit f7619a58ef92 ("drm/bridge: Patch atomic hooks to take a drm_bridge_state"). Commit 6ed7e9625fa6 ("drm/bridge: Add a drm_bridge_state object") introduced a circular dependency between drm.ko and drm_kms_helper.ko which uncovered a misdesign in how the whole thing was implemented. Let's revert all patches depending on the bridge_state infrastructure for now.

drm/bridge: Patch atomic hooks to take a drm_bridge_state

2020-01-07T09:10:59+00:00

This way the drm_bridge_funcs interface is consistent with the rest of the subsystem. The only driver implementing those hooks (analogix DP) is patched too.

drm/panel: decouple connector from drm_panel

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

To facilitate moving connector creation to display drivers, decouple the drm_connector from drm_panel. This patch adds a connector argument to drm_panel_get_modes(). All users of drm_panel_get_modes() already had the connector available, so updating users was trivial. With this patch drm_panel no longer keeps a reference to the drm_connector.

drm/bridge: anx6345: Fix compilation breakage on systems without CONFIG_OF

2019-11-13T08:52:44+00:00

The driver assumes that the platform uses the device tree, and thus relies on some fields (of_node) being declared in some structures (drm_bridge). This isn't true for all platforms, so make sure we can only compile the ANX6345 on platforms where DT support is selected.

drm/bridge: fix anx6345 compilation for v5.5

2019-11-12T19:20:25+00:00

The anx6345 driver originally was copied from anx78xx.c, which has meanwhile seen a few changes. In particular, the removal of drm_dp_link helpers and the discontinuation to include drm_bridge.h from drm_crtc.h breaks compilation in linux-5.5. Apply equivalents of these changes to anx6345.c.

The ANX6345 is an ultra-low power DisplayPower/eDP transmitter designed for portable devices. This driver adds initial support for RGB to eDP mode, without HPD and interrupts. This is a configuration usually seen in eDP applications.
