[PATCH v4 09/26] drm: sun4i: de3: pass engine reference to ccsc setup function

[Ryan Walklin <ryan@testtoast.com>]

From: Jernej Skrabec <jernej.skrabec@gmail.com>

Configuration of the DE3 colorspace and dynamic range correction module
requires knowledge of the current video format and encoding.

Pass the display engine by reference to the csc setup function, rather
than the register map alone, to allow access to this information.
