2018-07-13drm: Skip __drm_mode_set_config_internal() on atomic driversVille Syrjälä1-5/+10
Everything (apart from the actual ->set_config() call) __drm_mode_set_config_internal() does is now useless on atomic drivers. So let's just skip all the foreplay. v2: Use drm_drv_uses_atomic_modeset() (Daniel) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20180705190010.19836-1-ville.syrjala@linux.intel.com
2018-07-13drm: Introduce __setplane_atomic()Ville Syrjälä1-11/+57
All the plane->fb/old_fb/crtc dance of __setplane_internal() is pointless on atomic drivers. So let's just introduce a simpler version that skips all that. Ideally we could also skip the __setplane_check() as drm_atomic_plane_check() already checks for everything, but the legacy cursor/"async" .update_plane() tricks bypass that so we still need to call __setplane_check(). Toss in a FIXME to remind someone to clean this up later. v2: Use drm_drv_uses_atomic_modeset() (Daniel) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20180705185907.9524-1-ville.syrjala@linux.intel.com

When commit af11942ee44e ("drm/sun4i: tcon-top: Cleanup clock handling") was merged, the error handling path of the of_property_match_string was changed to take into account the fact that the returned value of that function wasn't an error pointer but an error code. Unfortunately, this introduced a warning since the now returned value is an integer, while the sun8i_tcon_top_register_gate function should return an error pointer. Fix that by calling ERR_PTR.

2018-07-12drm/sun4i: Implement zpos for DE2Jernej Skrabec4-37/+72
Initial implementation of DE2 planes only supported fixed zpos. Expand implementation with configurable zpos property. Implementation background: Channel in DE2 driver represents one DRM plane, whereas pipe is just mapped channel to known Z position. Pipe 0 will always be at the bottom, pipe 1 just above pipe 0 and so on. If, for example, channel 1 is mapped at pipe 0 and channel 0 at pipe 1, whatever is on channel 0 will appear on top. Before this commit, channel id was used for addressing channel related registers (prefixed with SUN8I_MIXER_CHAN_UI_ or SUN8I_MIXER_CHAN_VI_) and pipe registers (prefixed with SUN8I_MIXER_BLEND_). Additionally, register SUN8I_MIXER_BLEND_ROUTE, which takes care for mapping channels to pipes had fixed value. It mapped channel 0 to pipe 0, 1 to 1 and so on. Consequence of all that was fixed Z order of planes. With this commit, pipe registers are using zpos property as index and channel related registers still use channel id as index. Pipe mapping register is now set dynamically too and pipe enable register is rebuild every time to make sure only active pipes are enabled. Testing was done to confirm that there is no issues if bottom plane contains pixels with alpha value < 0xff and if it doesn't whole screen.

Currently, TCON supports 2 ways to match TCON with engine (mixer in this case). Old way is to just traverse of graph backwards and compare node pointer. New way is to match TCON and engine by their respective ids. All SoCs with DE2 enabled till now used the old way, which means mixer id was never used and thus never implemented. However, for R40, only the new way will be used. To prepare for that, implement mixer id fetching from DT.

Having a device with a status property != "okay" in the DT is a valid use case, and we should not prevent the registration of the DRM device when the DSI device connected to the DSI controller is disabled. Consider the ENODEV return code as a valid result and do not expose the DSI encoder/connector when it happens.
