Subject: [PATCH v5 1/3] media: dt-bindings: media: Document Rockchip VIP bindings
Add a documentation for the Rockchip Camera Interface controller
binding.
This controller can be found on platforms such as the PX30 or the
RK3288, the PX30 being the only platform supported so far.
Signed-off-by: Maxime Chevallier <maxime.chevallier@...tlin.com>
---
v3: Renamed the controller to "vip"
v4: fixed the binding to get a compiling example
v5: Fixed the binding even more, the 'endpoint' description was missing
