drm/arcpgu: fix device node leak

2026-04-14T09:21:48+00:00

This function gets a device_node reference via of_graph_get_remote_port_parent() and stores it in encoder_node, but never puts that reference. Add it. There used to be a of_node_put(encoder_node) but it has been removed by mistake during a rework in commit 3ea66a794fdc ("drm/arc: Inline arcpgu_drm_hdmi_init").

drm/panel-mipi-dbi: Use regular atomic helpers; drop simple-display helpers

2026-03-25T14:05:02+00:00

Replace simple-display helpers with regular atomic helpers. Store the pipeline elements in struct panel_mipi_dbi_device and initialize them as part of probing the device. Use mipi-dbi's existing helpers and initializer macros where possible. Effectively open-codes the modesetting code in the initializer helpers of mipi-dbi and simple-display. Panel-mipi-dbi requires a custom helper for CRTC enablement, and non-freeing cleanup of the pipeline. v2: - fix connector initialization Signed-off-by: Thomas Zimmermann Acked-by: David Lechner Tested-by: David Lechner Reviewed-by: Dmitry Baryshkov Link: https://patch.msgid.link/20260319160110.109610-11-tzimmermann@suse.de

drm/mipi-dbi: Only modify planes on enabled CRTCs

2026-03-25T14:04:24+00:00

Use drm_atomic_helper_commit_tail_rpm() as commit tail to update the plane after enabling the CRTC. Then remove the plane-update code from mipi_dbi_enable_flush() and inline the remaining backlight code where necessary. Mipi-dbi's current commit tail drm_atomic_helper_commit_tail() first updates the plane and then enables the CRTC. But the CRTC enablement includes power management that prevents the initial plane update from working. Hence, each mipi-dbi driver includes a plane update in their CRTC enablement; in the form of mipi_dbi_enable_flush() or custom code. Using drm_atomic_helper_commit_tail_rpm() enables the CRTC before any plane updates. Hence the additional plane update can be removed from mipi_dbi_enable_flush() and a number of drivers. This leaves backlight_enable() in the helper, which can now be inlined into affected drivers. Drivers now enable the CRTC plus an optional backlight and then automatically update the plane. In the case of disabling the display, drm_atomic_helper_commit_tail_rpm() only disables the CRTC without touching the plane at all. Mipi-dbi's mipi_dbi_pipe_disable() already contains the necessary logic. Removing the plane update from the CRTC enablement will also help with converting mipi-dbi from simple-pipe helpers to regular atomic helpers. v3: - st7586: remove unused variable v2: - ili9225: remove unused variables (David) - st7586: remove unused variables (David) Signed-off-by: Thomas Zimmermann Acked-by: David Lechner Reviewed-by: Dmitry Baryshkov Link: https://patch.msgid.link/20260319160110.109610-2-tzimmermann@suse.de
