From: Thierry Reding <tred...@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 Thierry Thierry Reding (13): drm/dp: Sort includes alphabetically drm/dp: Remove a gratuituous blank line drm/dp: Add drm_dp_fast_training_cap() helper drm/dp: Add drm_dp_channel_coding_supported() helper drm/dp: Add drm_dp_alternate_scrambler_reset_cap() helper drm/dp: Do not busy-loop during link training drm/dp: Add helper to get post-cursor adjustments drm/bridge: analogix-anx78xx: Avoid drm_dp_link helpers drm/bridge: tc358767: Avoid drm_dp_link helpers drm/bridge: tc358767: Use DP nomenclature drm/msm: edp: Avoid drm_dp_link helpers drm/rockchip: Avoid drm_dp_link helpers drm/tegra: Move drm_dp_link helpers to Tegra DRM drivers/gpu/drm/bridge/analogix-anx78xx.c | 57 ++++++-- drivers/gpu/drm/bridge/tc358767.c | 65 ++++++--- drivers/gpu/drm/drm_dp_helper.c | 169 ++++------------------ drivers/gpu/drm/msm/edp/edp_ctrl.c | 70 ++++++--- drivers/gpu/drm/rockchip/cdn-dp-core.c | 12 +- drivers/gpu/drm/rockchip/cdn-dp-core.h | 3 +- drivers/gpu/drm/rockchip/cdn-dp-reg.c | 19 ++- drivers/gpu/drm/tegra/Makefile | 1 + drivers/gpu/drm/tegra/dp.c | 133 +++++++++++++++++ drivers/gpu/drm/tegra/dp.h | 26 ++++ drivers/gpu/drm/tegra/dpaux.c | 1 + drivers/gpu/drm/tegra/sor.c | 1 + include/drm/drm_dp_helper.h | 51 ++++--- 13 files changed, 373 insertions(+), 235 deletions(-) create mode 100644 drivers/gpu/drm/tegra/dp.c create mode 100644 drivers/gpu/drm/tegra/dp.h -- 2.23.0 _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
