2018-07-13drm: add support for DisplayPort CEC-Tunneling-over-AUXHans Verkuil
This adds support for the DisplayPort CEC-Tunneling-over-AUX feature that is part of the DisplayPort 1.3 standard. Unfortunately, not all DisplayPort/USB-C to HDMI adapters with a chip that has this capability actually hook up the CEC pin, so even though a CEC device is created, it may not actually work.

2018-07-13drm/i915/glk: Add Quirk for GLK NUC HDMI port issues.Clint Taylor
On GLK NUC platforms the HDMI retiming buffer needs additional disabled time to correctly sync to a faster incoming signal. When measured on a scope the highspeed lines of the HDMI clock turn off for ~400uS during a normal resolution change. The HDMI retimer on the GLK NUC appears to require at least a full frame of quiet time before a new faster clock can be correctly sync'd. Wait 100ms due to msleep inaccuracies while waiting for a completed frame. Add a quirk to the driver for GLK boards that use ITE66317 HDMI retimers. V2: Add more devices to the quirk list V3: Delay increased to 100ms, check to confirm crtc type is HDMI. V4: crtc type check extended to include _DDI and whitespace fixes v5: Fix white spaces, remove the macro for delay. Revert the crtc type check introduced in v4.

2018-07-12drm/i915: Use crtc_state->has_psr instead of CAN_PSR for pipe updateTarun Vyas
In commit "drm/i915: Wait for PSR exit before checking for vblank evasion", the idea was to limit the PSR IDLE checks when PSR is actually supported. While CAN_PSR does do that check, it doesn't applies on a per-crtc basis. crtc_state->has_psr is a more granular check that only applies to pipe(s) that have PSR enabled. Without the has_psr check, we end up waiting on the eDP transcoder's PSR_STATUS register irrespective of whether the pipe being updated is driving it or not. v2: Remove unnecessary parantheses, make checkpatch happy. v3: Move the has_psr check to intel_psr_wait_for_idle and commit message changes (DK). v4: Derive dev_priv from intel_crtc_state (DK) v5: Commit message changes to reflect the HW behavior (DK) Fixes: a608987970b9 ("drm/i915: Wait for PSR exit before checking for vblank evasion") Reviewed-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Signed-off-by: Tarun Vyas <tarun.vyas@intel.com> Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180712053323.26266-1-tarun.vyas@intel.com

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 Skrabec
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.

2018-07-12drm/i915: Silence warning for no vlv powercontextChris Wilson
Along a module load error path, we may try to cleanup the powercontext even before we have allocated it. Reorganising GT powermanagement is an on going process, so for simplicity handle it.

2018-07-12drm/sun4i: fix build failure with CONFIG_DRM_SUN8I_MIXER=mArnd Bergmann
Having DRM_SUN4I built-in but DRM_SUN8I_MIXER as a loadable module results in a link error, as we try to access a symbol from the sun8i_tcon_top.ko module: ERROR: "sun8i_tcon_top_of_table" [drivers/gpu/drm/sun4i/sun8i-drm-hdmi.ko] undefined! ERROR: "sun8i_tcon_top_of_table" [drivers/gpu/drm/sun4i/sun4i-drm.ko] undefined! This solves the problem by adding a silent symbol for the tcon_top module, building it as a separate module in exactly the cases that we need it, but in a way that it is reachable by the other modules.

2018-07-12drm/sun4i: mixer: Read id from DTJernej Skrabec
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.

2018-07-12drm/vkms: Add vblank events simulated by hrtimersRodrigo Siqueira
This commit adds regular vblank events simulated through hrtimers, which is a feature required by VKMS to mimic real hardware. Additionally, all the vblank event send after pageflip is kept in the atomic_flush function. Changes since V1: - Compute the vblank timer interval per interruption Ville Syrjälä and Daniel Vetter: - Removes hardcoded vblank interval to get it from user space Changes since V2: Chris Wilson - Removes unnecessary algorithm to compute the next period Daniel Vetter: - Uses drm_calc_timestamping_constants to get the vblank interval instead of calculating it manually - Adds disable_vblank helper that turns of crtc - Simplifies implementation by using drm_crtc_arm_vblank_event - Replaces the code in atomic_begin to atomic_flush - Removes unnecessary field in vkms_output Changes since V3: Daniel Vetter: - Squash "drm/vkms: Add atomic helpers functions" into the commit that handling vblank events simulated by hrtimers Signed-off-by: Rodrigo Siqueira <rodrigosiqueiramelo@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/7709bba40782ec06332d57fff337797b272581fc.1531359228.git.rodrigosiqueiramelo@gmail.com
