drm/tegra: dc: Implement runtime PM

2016-07-04T09:35:46Z

Use runtime PM to clock-gate, assert reset and powergate the display controller. This ties in nicely with atomic DPMS in that a runtime PM reference is taken before a pipe is enabled and dropped after it has been shut down. To make sure this works, make sure to only ever update planes on active CRTCs, otherwise register accesses to a clock-gated and reset CRTC will hang the CPU. Signed-off-by: Thierry Reding

drm: Drop plane argument from __drm_atomic_helper_plane_destroy_state

2016-05-17T06:56:55Z

It's unused, and really this helper should only look at the state structure and nothing else. v2: Fix commit message (Laurent). v3: Rebase onto mtk driver merge.

drm/tegra: Don't set a gamma table size

2016-03-31T10:30:12Z

Tegra doesn't have any functions to set gamma tables, so this is completely defunct. Not nice to lie to userspace, so let's stop! Cc: Thierry Reding Signed-off-by: Daniel Vetter Signed-off-by: Thierry Reding

drm/tegra: Stop cancelling page flip events

Merge tag 'drm/tegra/for-4.5-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next

2015-12-16T22:38:57Z

drm/tegra: Changes for v4.5-rc1 This adds support for the version of host1x found on Tegra210 SoCs. It also makes use of the new atomic suspend/resume functionality to bring this feature to Tegra. Other than that it's mostly small fixes and cleanups, with some prep- work for things that will hopefully get merged for the next release. * tag 'drm/tegra/for-4.5-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: Advertise DRIVER_ATOMIC drm/tegra: Use DRIVER level for IOMMU aperture message drm/tegra: checking for IS_ERR() instead of NULL drm/tegra: dc: Add missing of_node_put() drm/tegra: Implement subsystem-level suspend/resume drm/tegra: sor: Remove unnecessary conditional drm/tegra: sor: Operate on struct drm_dp_aux * drm/tegra: Use drm_gem_object_unreference_unlocked() drm/tegra: Don't take dev->struct_mutex in mmap offset ioctl drm/tegra: Use unlocked gem unreferencing drm/tegra: Use new multi-driver module helpers gpu: host1x: Add Tegra210 support gpu: host1x: Remove core driver on unregister gpu: host1x: Use platform_register/unregister_drivers()

drm/tegra: dc: Add missing of_node_put()

2015-12-14T10:40:55Z

for_each_matching_node() performs an of_node_get() on each iteration, so a break out of the loop requires an of_node_put(). A simplified version of the semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // @@ local idexpression n; expression e; @@ for_each_matching_node(n,...) { ... ( of_node_put(n); | e = n | + of_node_put(n); ? break; ) ... } ... when != n // Signed-off-by: Julia Lawall Signed-off-by: Thierry Reding

drm: Pass 'name' to drm_universal_plane_init()

2015-12-11T08:13:10Z

Done with coccinelle for the most part. It choked on msm/mdp/mdp5/mdp5_plane.c like so: "BAD:!!!!! enum drm_plane_type type;" No idea how to deal with that, so I just fixed that up by hand. Also 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_plane_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. @@ typedef uint32_t; identifier dev, plane, possible_crtcs, funcs, formats, format_count, type; @@ int drm_universal_plane_init(struct drm_device *dev, struct drm_plane *plane, unsigned long possible_crtcs, const struct drm_plane_funcs *funcs, const uint32_t *formats, unsigned int format_count, enum drm_plane_type type + ,const char *name, int DOTDOTDOT ) { ... } @@ identifier dev, plane, possible_crtcs, funcs, formats, format_count, type; @@ int drm_universal_plane_init(struct drm_device *dev, struct drm_plane *plane, unsigned long possible_crtcs, const struct drm_plane_funcs *funcs, const uint32_t *formats, unsigned int format_count, enum drm_plane_type type + ,const char *name, int DOTDOTDOT ); @@ expression E1, E2, E3, E4, E5, E6, E7; @@ drm_universal_plane_init(E1, E2, E3, E4, E5, E6, E7 + ,NULL ) v2: Split crtc and plane changes apart Pass NUL for no-name instead of "" Leave drm_plane_init() alone v3: Add ', or NULL...' to @name kernel doc (Jani) Annotate the function with __printf() attribute (Jani) Signed-off-by: Ville Syrjälä Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1449670795-2853-1-git-send-email-ville.syrjala@linux.intel.com
