Hi Maxime, As promised, here is the patch adding the interrupt line for the display backend to the sun5i shared dtsi, and another one adding it to the device tree bindings.
The display backend has an undocumented (in the user manual) interrupt that, according to vendor code, is raised when the current scanout is completed. This might be a better fit for DRM/KMS vblank signalling, rather than the TCON's vblank interrupt. If true, it would allow us to cut out the TCON from the crtc in the driver, instead keeping it solely as an encoder, simplifying some of the inter-component code. Regardless, the interrupt line exists and should be added to the device tree.
