2025-04-29drm/vc4: convert to devm_drm_bridge_alloc() APILuca Ceresoli
This is the new API for allocating DRM bridges. This driver already implements refcounting of the struct vc4_dsi, which embeds struct drm_bridge. Now this is a duplicate of the refcounting implemented by the DRM bridge core, so convert the vc4_dsi_get/put() calls into drm_bridge_get/put() calls and get rid of the driver-specific refcounting implementation.

2025-04-27drm/mediatek: mtk_dpi: Use switch in mtk_dpi_config_color_format()AngeloGioacchino Del Regno
In preparation for adding support for an additional color format, convert the format conditional in mtk_dpi_config_color_format() to a switch. This also makes the concept of RGB being the default color format a little more human readable. This commit brings no functional differences.

2025-04-25drm/i915/vga: Consolidate intel_vga_disable() callsVille Syrjälä
Currently we disable the VGA plane from various places, sometimes multiple times in the same init/resume sequence. Get rid of all this mess and do it just once. The most correct place seems to be just after intel_early_display_was() as that one applies various workarounds that need to be in place before we touch any planes (including the VGA plane). Actually, we do still have a second caller in vlv_display_power_well_init(). I think we still need that as the reset value of VGACNTR is 0x0 and thus technically the VGA plane will be (at least partially) enabled after the power well has been toggled. In both cases we have the necessary power reference already held (INIT power domain for load/resume case, and the display power well itself being what we need for vlv_display_power_well_init()).
