Hi,
Following up on the discussion about the usefulness of the drm_dp_link helpers, here's a new series that adds a couple of new DPCD parser functions and then pushes the drm_dp_link helpers down into drivers. For most drivers this was pretty easy to do since they didn't heavily rely on the struct drm_dp_link. I decided to move the drm_dp_link helpers to the Tegra driver because they are more heavily used there and I have a subsequent series that adds support for DisplayPort on various Tegra boards based on those helpers.
The plan is to merge this series into drm-misc once reviewed so that I can rebase my Tegra DP support patches on that, hopefully in time for v5.5.
I don't have access to the bridges, Rockchip or MSM hardware, so those drivers are only build-tested. Since this series really only replaces variables, I don't think there's a high risk of breaking anything.
Changes in v3: - drop drm_dp_aux_rd_interval() helper patch; this turned out to be incomplete and fixing it made it useless over existing helpers - add Reviewed-by from Lyude - address review comments
