Subject: [PATCH v2 0/5] Add interconnent support for simpledrm/simplefb

Some devices might require keeping an interconnect path alive so that
the framebuffer continues working. Add support for that by setting the
bandwidth requirements appropriately for all provided interconnect
paths.

Signed-off-by: Luca Weiss <luca.weiss@...rphone.com>

Changes in v2:
- Sort the headers before adding the new interconnect header, in
  separate commits.
- Use the correct #if guards for new interconnect code
- Pick up tags
- Link to v1: https://lore.kernel.org/r/20250620-simple-drm-fb-icc-v1-0-d92142e8f74f@fairphone.com
