Subject: [PATCH v3 00/13] drm/dp: Move drm_dp_link helpers to Tegra DRM
Date: Mon, 21 Oct 2019 16:34:24 +0200	[thread overview]
Message-ID: <20191021143437.1477719-1-thierry.reding@gmail.com> (raw)

From: Thierry Reding <treding@nvidia.com>

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
