2019-10-24drm/tegra: sor: Move register programming out of ->init()Thierry Reding
The hardware is not guaranteed to be enabled during execution of the tegra_sor_init() function, which can lead to a crash on some Tegra SoCs. Fix this by moving all register programming into code that is guaranteed to only be executed when the hardware is enabled. Signed-off-by: Thierry Reding <treding@nvidia.com>
2019-10-23drm/tegra: Move drm_dp_link helpers to Tegra DRMThierry Reding
During the discussion of patches that enhance the drm_dp_link helpers it was concluded that these helpers aren't very useful to begin with. After all other drivers have been converted not to use these helpers anymore, move these helpers into the last remaining user: Tegra DRM. If at some point these helpers are deemed more widely useful, they can be moved out into the DRM DP helpers again.
