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.

drm/stm/lvds: convert from round_rate() to determine_rate()

2025-09-15T13:08:44+00:00

The round_rate() clk ops is deprecated, so migrate this driver from round_rate() to determine_rate() using the Coccinelle semantic patch on the cover letter of this series.

drm/stm: ltdc: handle lvds pixel clock

2025-08-28T15:43:57+00:00

Handle LVDS pixel clock. The LTDC operates with multiple clock domains for register access, requiring all clocks to be provided during read/write operations. This imposes a dependency between the LVDS and LTDC to access correctly all LTDC registers. And because both IPs' pixel rates must be synchronized, the LTDC has to handle the LVDS clock.

drm/bridge: Add encoder parameter to drm_bridge_funcs.attach

2025-03-20T13:45:38+00:00

The drm_bridge structure contains an encoder pointer that is widely used by bridge drivers. This pattern is largely documented as deprecated in other KMS entities for atomic drivers. However, one of the main use of that pointer is done in attach to just call drm_bridge_attach on the next bridge to add it to the bridge list. While this dereferences the bridge->encoder pointer, it's effectively the same encoder the bridge was being attached to. We can make it more explicit by adding the encoder the bridge is attached to to the list of attach parameters. This also removes the need to dereference bridge->encoder in most drivers.

It's pretty inconvenient to access the full atomic state from drm_bridges, so let's change the atomic_disable hook prototype to pass it directly.
