drm/mcde: Fix refcount leak in mcde_dsi_bind

2022-06-27T07:58:41+00:00

Every iteration of for_each_available_child_of_node() decrements the reference counter of the previous node. There is no decrement when break out from the loop and results in refcount leak. Add missing of_node_put() to fix this.

Revert "drm: bridge: mcde_dsi: Switch to devm_drm_of_get_bridge"

2022-05-04T15:06:31+00:00

commit <3d7039e1e649> ("drm: bridge: mcde_dsi: Switch to devm_drm_of_get_bridge") switched to devm_drm_of_get_bridge for looking up if child node has panel or bridge. However commit ("Revert "drm: of: Lookup if child node has panel or bridge") has reverted panel or bridge child node lookup from devm_drm_of_get_bridge as it breaks the non-trivial cases the first child node might not be a panel or bridge. So, revert this commit to switch the previous behavior of looking up child panel or bridge.

drm: bridge: mcde_dsi: Drop explicit bridge remove

2022-04-04T09:14:32+00:00

This driver has been changed to use the resource managed devm_drm_of_get_bridge() to get bridge from ->bind(), it's unnecessary to call drm_of_panel_bridge_remove() to remove the bridge from ->unbind() as devm_drm_of_get_bridge() is automatically remove the bridge when @dev is unbound. Drop it the drm_bridge_remove().

devm_drm_of_get_bridge is capable of looking up the downstream bridge and panel and trying to add a panel bridge if the panel is found. Replace explicit finding calls with devm_drm_of_get_bridge.

drm/bridge: Centralize error message when bridge attach fails

2021-07-28T13:33:12+00:00

Being informed of a failure to attach a bridge is useful, and many drivers prints an error message in that case. Move the message to drm_bridge_attach() to avoid code duplication. Suggested-by: Stephen Boyd Signed-off-by: Laurent Pinchart Reviewed-by: Tomi Valkeinen Reviewed-by: Jyri Sarha

drm/dsi: Add _NO_ to MIPI_DSI_* flags disabling features

2021-07-27T07:48:24+00:00

Many of the DSI flags have names opposite to their actual effects, e.g. MIPI_DSI_MODE_EOT_PACKET means that EoT packets will actually be disabled. Fix this by including _NO_ in the flag names, e.g. MIPI_DSI_MODE_NO_EOT_PACKET.
