2017-10-20drm/tegra: dc: Perform a complete reset sequenceThierry Reding
In order for the reset to be applied properly, the module clock must be enabled during the assertion. Signed-off-by: Thierry Reding <treding@nvidia.com>
2017-10-20drm/tegra: dc: Make sure to set the module clock rateThierry Reding
When applying the PLL changes from the computed state object, make sure to set the rate of the display controller module clock. Failing to do so can yield to a situation where the parent will be set to the proper pixel clock, but the module clock will be divided down to the rate that is happened to be set to before the parent rate change.

2017-10-20drm/tegra: dc: Simplify atomic plane helper functionsThierry Reding
Remove the tegra_dc_disable_window() function whose only purpose was to allow tegra_plane_atomic_update() to also call it. Fix that by shuffling tegra_plano_atomic_disable() to before tegra_plane_atomic_update(). While at it, also remove the overlay plane helper functions because they are exactly the same as the primary plane helper functions. Signed-off-by: Thierry Reding <treding@nvidia.com>

2017-10-20drm/tegra: dc: Use of_device_get_match_data()Thierry Reding
Avoid some boilerplate by calling of_device_get_match_data() instead of open-coding the equivalent in the driver. Signed-off-by: Thierry Reding <treding@nvidia.com>
2017-10-20gpu: host1x: syncpt: Request syncpoints per clientThierry Reding
Rather than request syncpoints for a struct device *, request them for a struct host1x_client *. This is important because subsequent patches are going to break the assumption that host1x will always be the parent for devices requesting a syncpoint. It's also a more natural choice because host1x clients are really the only ones that will know how to deal with syncpoints. Note that host1x clients are always guaranteed to be children of host1x, regardless of their location in the device tree. Signed-off-by: Thierry Reding <treding@nvidia.com>
2017-08-01drm: Plumb modifiers through plane initBen Widawsky
This is the plumbing for supporting fb modifiers on planes. Modifiers have already been introduced to some extent, but this series will extend this to allow querying modifiers per plane. Based on this, the client to enable optimal modifications for framebuffers. This patch simply allows the DRM drivers to initialize their list of supported modifiers upon initializing the plane. v2: A minor addition from Daniel v3: * Updated commit message * s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu) * Remove some excess newlines (Liviu) * Update comment for > 64 modifiers (Liviu) v4: Minor comment adjustments (Liviu) v5: Some new platforms added due to rebase v6: Add some missed plane inits (or maybe they're new - who knows at this point) (Daniel) Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Daniel Stone <daniels@collabora.com> (v2) Reviewed-by: Liviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: Daniel Stone <daniels@collabora.com>
2017-06-30drm: Convert atomic drivers from CRTC .disable() to .atomic_disable()Laurent Pinchart
The CRTC .disable() helper operation is deprecated for atomic drivers, the new .atomic_disable() helper operation being preferred.

2017-06-30drm: Add old state pointer to CRTC .enable() helper functionLaurent Pinchart
The old state is useful for drivers that need to perform operations at enable time that depend on the transition between the old and new states. While at it, rename the operation to .atomic_enable() to be consistent with .atomic_disable(), as the .enable() operation is used by atomic helpers only.

The vblank hooks in struct drm_driver are deprecated and only meant for legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks in struct drm_crtc_funcs should be used instead.

2015-12-11drm: Pass 'name' to drm_crtc_init_with_planes()Ville Syrjälä
Done with coccinelle for the most part. However, it thinks '...' is part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder in its place and got rid of it with sed afterwards. I didn't convert drm_crtc_init() since passing the varargs through would mean either cpp macros or va_list, and I figured we don't care about these legacy functions enough to warrant the extra pain. @@ identifier dev, crtc, primary, cursor, funcs; @@ int drm_crtc_init_with_planes(struct drm_device *dev, struct drm_crtc *crtc, struct drm_plane *primary, struct drm_plane *cursor, const struct drm_crtc_funcs *funcs + ,const char *name, int DOTDOTDOT ) { ... } @@ identifier dev, crtc, primary, cursor, funcs; @@ int drm_crtc_init_with_planes(struct drm_device *dev, struct drm_crtc *crtc, struct drm_plane *primary, struct drm_plane *cursor, const struct drm_crtc_funcs *funcs + ,const char *name, int DOTDOTDOT ); @@ expression E1, E2, E3, E4, E5; @@ drm_crtc_init_with_planes(E1, E2, E3, E4, E5 + ,NULL ) v2: Split crtc and plane changes apart Pass NULL for no-name instead of "" Leave drm_crtc_init() alone v3: Add ', or NULL...' to @name kernel doc (Jani) Annotate the function with __printf() attribute (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1449670771-2751-1-git-send-email-ville.syrjala@linux.intel.com

2015-10-30drm/tegra: dc: Request/free syncpoint at init/exitThierry Reding
syncpoints are resources provided by host1x and their lifetime is tied to the host1x device. They are not properly reference counted either, so removing the host1x device before any of its clients causes a use-after- free error. Adding proper reference counting would be a major enterprise so work around it for now by requesting and freeing the syncpoint at init and exit time, respectively. The host1x device is guaranteed to be around at this point. Signed-off-by: Thierry Reding <treding@nvidia.com>

git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.3-rc1 There are a bunch of non-critical fixes here that I've collected over the past few months, but the biggest part is Tegra210 support, in the DC, DSI and SOR/HDMI drivers.

git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.1-rc1 Perhaps the most noteworthy change in this set is the implementation of a hardware VBLANK counter using host1x syncpoints. The SOR registers can now be dumped via debugfs, which can be useful while debugging. The IOVA address space maintained by the driver can also be dumped via debugfs. Other than than, these changes are mostly cleanup work, such as making register names more consistent or removing unused code (that was left over after the atomic mode-setting conversion). There's also a fix for eDP that makes the driver cope with firmware that already initialized the display (such as the firmware on the Tegra-based Chromebooks). * tag 'drm/tegra/for-4.1-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: sor: Reset during initialization drm/tegra: gem: Return 64-bit offset for mmap(2) drm/tegra: hdmi: Name register fields consistently drm/tegra: hdmi: Resets are synchronous drm/tegra: dc: Document tegra_dc_state_setup_clock() drm/tegra: dc: Remove unused callbacks drm/tegra: dc: Remove unused function drm/tegra: dc: Use base atomic state helpers drm/atomic: Add helpers for state-subclassing drivers drm/tegra: dc: Implement hardware VBLANK counter gpu: host1x: Export host1x_syncpt_read() drm/tegra: sor: Dump registers via debugfs drm/tegra: sor: Registers are 32-bit drm/tegra: Provide debugfs file for the IOVA space drm/tegra: dc: Check for valid parent clock
