With armada the last bigger driver that realistically needed these to convert from legacy kms to atomic is converted. These helpers have been broken more often than not the past 2 years, and as this little patch series shows, tricked a bunch of people into using the wrong helpers for their functions. Aside: I think a lot more drivers should be using the device-level drm_atomic_helper_shutdown/suspend/resume helpers and related functions. In almost all the cases they get things exactly right.

drm_plane_helper_disable is a non-atomic drivers only function, and will blow up (since no one passes the locking context it needs). Atomic drivers which want to quiescent their hw on unload should use drm_atomic_helper_shutdown() instead. Reviewed-by:

Atomic drivers which want to quiescent their hw on unload should use drm_atomic_helper_shutdown() instead. The sti cleanup code seems supremely confused: - In the load error path it calls drm_mode_config_cleanup before it stops various kms services like poll worker or fbdev emulation. That's going to oops. - The actual unload code doesn't even bother with the cleanup and just leaks. Try to fix this while at it. Reviewed-by:

It's the default. The exported version was kinda a transition state, before we made this the default. To stop new atomic drivers from using it (instead of just relying on the default) let's unexport it. v2: rename the default implementation to a more fitting name and add a comment (Laurent) Signed-off-by:

For atomic driver this is the default, no need to reimplement it. We still need to keep the copypasta for not-atomic drivers though, since no one polished the legacy crtc helpers as much as the atomic ones. v2: amdgpu uses ->best_encoder internally, give it a local copy. It might be a good idea to merge the connector and encoder into one amdgpu_dm_sink structure, that might match DC internals better. At least for non-DPMST outputs. Kudos to Ville for spotting this. v3: Rebase onto a487411a ("drm/amd/display: Use DRM helper for best_encoder"). Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Let's make the infoframe pack functions usable with a const infoframe structure. This allows us to precompute the infoframe earlier, and still pack it later when we're no longer allowed to modify the structure. So now we end up with a _check()+_pack_only() or _pack() functions depending on whether you want to precompute the infoframes or not. The names aren't great but I was lazy and didn't want to change all the drivers. v2: Deal with exynos churn Actually export the new funcs v3: Fix various documentation fails (Hans) Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Hans Verkuil <hans.verkuil@cisco.com> Cc: linux-media@vger.kernel.org Signed-off-by:Hans Verkuil <hans.verkuil@cisco.com>

In preparation to remove the node name pointer from struct device_node, convert printf users to use the %pOFn format specifier. For drm_modes.c, the full node path is already printed out, so printing just the node name a 2nd time is redundant and can be removed.

When using special phy handling operations we'll often need access to the rockchip_hdmi struct. As the chip-data that occupies the phy_data pointer initially gets assigned to the rockchip_hdmi struct, we can now re-use this phy_data pointer to hold the reference to the rockchip_hdmi struct and use this reference later on. Inspiration for this comes from meson and sunxi dw-hdmi, which are using the same method. changes in v3: - reword commit message Signed-off-by:

So far we always encountered socs with 2 output crtcs needing the driver to tell the hdmi block which output to connect to. But there also exist socs with only one crtc like the rk3228, rk3328 and rk3368. So adapt the register field to simply carry a negative value to signal that no output-switching is necessary. changes in v3: - fixed wording issue found by Robin Murphy Signed-off-by:

Heiko Stuebner authored
In some IP implementations the reading of the phy-type may be broken. One example are the Rockchip rk3228 and rk3328 socs that use a separate vendor-type phy from Innosilicon but still report the HDMI20_TX type. So allow the glue driver to force the vendor-phy for these cases. In the future it may be necessary to allow forcing other types, but for now we'll keep it simply to the case actually seen in the wild. changes in v3: - only allow forcing vendor type, as suggested by Laurent Signed-off-by:

This panel is marketed as Banana Pi 7" LCD display. On the back is a sticker denoting the model name S070WV20-CT16. This is a 7" 800x480 panel connected through a 24-bit RGB interface. However the panel only does 262k colors. Depending on the variant, the PCB attached to the panel module either supports DSI, or DSI + 24-bit RGB. DSI is converted to 24-bit RGB via an onboard ICN6211 MIPI DSI - RGB bridge chip, then fed to the panel itself. Signed-off-by:
