drm/meson: use default case for unsupported DSI pixel formats

2026-03-25T12:06:10+00:00

Use default instead of listing unsupported formats explicitly, so the switch statements don't need updating each time a new pixel format is added.

drm/meson/dw-hdmi: convert to of_drm_find_and_get_bridge()

2026-01-21T12:59:56+00:00

of_drm_find_bridge() is deprecated. Move to its replacement of_drm_find_and_get_bridge() which gets a bridge reference, and ensure it is put when done. dw_hdmi->bridge is used only in dw_hdmi_top_thread_irq(), so in order to avoid potential use-after-free ensure the irq is freed before putting the dw_hdmi->bridge reference.

drm/meson: venc: add support for HDMI DMT modes up to 3840x2160

2026-01-05T15:09:57+00:00

Commit 5d0bfe448481 ("drm/meson: Add HDMI 1.4 4k modes") added support for HDMI 1.4 4k modes, which is what TVs need. For computer monitors the code is using the DMT code-path, which ends up in meson_venc_hdmi_supported_mode(), which does not allow the 4k modes yet. The datasheet for all supported SoCs mentions "4Kx2K@60". It's not clear whether "4K" here means 3840 or 4096 pixels. Allow resolutions up to 3840x2160 pixels (including middle steps, such as WQHD at 2560x1440 pixels) so they can be used with computer monitors (using the DMT code-path in the driver).

drm/meson: encoder_hdmi: get/put the next bridge

2025-12-30T09:11:33+00:00

This driver obtains a bridge pointer from of_drm_find_bridge() in the probe function and stores it until driver removal. of_drm_find_bridge() is deprecated. Move to of_drm_find_and_get_bridge() for the bridge to be refcounted and use bridge->next_bridge to put the reference on deallocation.

drm/bridge: add connector argument to .hpd_notify callback

2025-12-24T22:22:13+00:00

Drivers might need to update DRM connector in the drm_bridge_funcs.hpd_notify callback (e.g. it might be necessary to update EDID before setting ELD). Add corresponding argument to the callback.

drm: include drm_print.h where needed

2025-10-31T08:34:52+00:00

There are a gazillion files that depend on drm_print.h being indirectly included via drm_buddy.h, drm_mm.h, or ttm/ttm_resource.h. In preparation for removing those includes, explicitly include drm_print.h where needed.
