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: rcar-du: Add r8a77980 support

2019-12-18T00:40:29+00:00

Add direct support for the r8a77980 (V3H). The V3H shares a common, compatible configuration with the r8a77970 (V3M) so that device info structure is reused. Signed-off-by: Kieran Bingham Reviewed-by: Laurent Pinchart Signed-off-by: Laurent Pinchart

drm: rcar-du: lvds: Allow for even and odd pixels swap

2019-12-18T00:40:26+00:00

DT properties dual-lvds-even-pixels and dual-lvds-odd-pixels can be used to work out if the driver needs to swap even and odd pixels around. This patch makes use of the return value from function drm_of_lvds_get_dual_link_pixel_order to determine if we need to swap odd and even pixels around for things to work properly. The dual_link boolean field from struct rcar_lvds is not sufficient to describe the type of LVDS link anymore, since we now have information related to pixel order, therefore rename it to link_type and repurpose its usage to fit the new requirements.

drm: rcar-du: lvds: Get dual link configuration from DT

2019-12-18T00:40:23+00:00

For dual-LVDS configurations, it is now possible to mark the DT port nodes for the sink with boolean properties (like dual-lvds-even-pixels and dual-lvds-odd-pixels) to let drivers know the encoders need to be configured in dual-LVDS mode. Rework the implementation of rcar_lvds_parse_dt_companion to make use of the DT markers while keeping backward compatibility.

drm: rcar-du: lvds: Improve identification of panels

Dual-LVDS panels are mistakenly identified as bridges, this commit replaces the current logic with a call to drm_of_find_panel_or_bridge to sort that out. Signed-off-by: Fabrizio Castro Reviewed-by: Laurent Pinchart Signed-off-by: Laurent Pinchart

drm: rcar-du: lvds: Get mode from state

2019-12-18T00:40:11+00:00

The R-Car LVDS encoder driver implements the bridge .mode_set() operation for the sole purpose of storing the mode in the LVDS private data, to be used later when enabling the encoder. Switch to the bridge .atomic_enable() and .atomic_disable() operations in order to access the global atomic state, and get the mode from the state instead. Remove both the unneeded .mode_set() operation and the display_mode and mode fields storing state data from the rcar_lvds private structure. As a side effect we get the CRTC from the state, replace the CRTC pointer retrieved through the bridge's encoder that shouldn't be used by atomic drivers. While at it, clarify a few error messages in rcar_lvds_get_lvds_mode() and turn them into warnings as they are not fatal.

drm: rcar-du: Recognize "renesas,vsps" in addition to "vsps"

2019-12-18T00:40:10+00:00

The Renesas-specific "vsps" property lacks a vendor prefix. Add a "renesas," prefix to comply with DT best practises. Retain backward compatibility with old DTBs by falling back to "vsps" when needed.
