A struct device doesn't carry much information that a channel might be interested in, but the client very much does. Request channels for the clients rather than their parent devices and store a pointer to them in order to have that information available when needed.

It's technically not required to explicitly initialize the fields that will be zero by default, but it's easier to read these structures if they are all initialized uniformly. Signed-off-by: -

Commit Fixes: b9f8b09c ("drm/tegra: Setup shared IOMMU domain after initialization") changed the initialization order of the IOMMU related bits but didn't update the cleanup path accordingly. This asymmetry can cause failures during error recovery. Fixes: b9f8b09c ("drm/tegra: Setup shared IOMMU domain after initialization") Signed-off-by:

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:

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. Signed-off-by:

If the transmitter supports pre-emphasis post cursor2 the sink will request adjustments in a similar way to how it requests adjustments to the voltage swing and pre-emphasis settings. Add a helper to extract these adjustments on a per-lane basis from the DPCD link status. Reviewed-by:

Use microsecond sleeps for the clock recovery and channel equalization delays during link training. The duration of these delays can be from 100 us up to 16 ms. It is rude to busy-loop for that amount of time. While at it, also convert to standard coding style by putting the opening braces in a function definition on a new line. Also switch to using an unsigned int for the AUX read interval to match the data type of the parameters to usleep_range(). v2: use correct multiplier for training delays (Philipp Zabel) v3: clarify data type change in commit message Signed-off-by:

This reverts commit 23b48225. This patch does not have an acceptable open source userspace implementation, and as such it does not meet the requirements for adding new UAPI.

This is not something we'll fix, because failing to clean up stuff (or doing it in the wrong order) is a driver bug. The offending FIXME goes all the way back to the original modeset merge. We've added a WARN_ON in commit 2b677e8c Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Dec 10 21:16:05 2012 +0100 drm: reference framebuffers which are on the idr including a comment blaming drivers on this. Right thing to do is most likely drm_atomic_helper_shutdown plus making sure that drm_mode_config_cleanup is not called too early (i.e. not in driver unload, but only in the final drm_device release callback).
