drm/tegra: rgb: Implement ->atomic_check() The implementation of the ->atomic_check() callback precomputes all parameters to check if the given configuration can be applied. If so the precomputed values are stored in the atomic state object for the encoder and applied during modeset. In that way the modeset no longer needs to perform any checking but simply program values into registers. Signed-off-by: Thierry Reding <treding@nvidia.com>
