Hi,
This is a fourth attempt at supporting the LVDS dual-link output on the
Allwinner A20.
Let me know what you think,
Maxime
Changes from v4:
- Rebased on 5.15
Changes from v3:
- Reintroduce the endpoint sanity check (and make of_graph_get_port_by_id
const in the process)
- Make a few doc fixes
- Fix device_node leakage
- Changed allwinner,lvds-companion to more generic link-companion
- Rebased on 5.11
Changes from v2:
- Added the DT binding description
- Split the patch to enable the A20
- Reworked a bit the error messages
Changes from v1:
- Reworked the DT bindings
- Refactored a bit the panel registration in the tcon code.
