2020-02-12drm: lt8912: Change the way the hpd gpio os being accessedPhilippe Schenker
This commit changes gpiod_get_value to gpiod_get_value_cansleep so it doesn't crash when trying to access a GPIO from a gpio expander over i2c. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
2020-02-12gpio: pca953x: Use PCA_LATCH_INTAndy Shevchenko
The commit 0cdf21b34e30 ("gpio: pca953x: set the PCA_PCAL flag also when matching by DT") introduces a helper macro which tells that chip supports latched interrupts, but the macro was never used for ACPI or legacy enumeration. So, make use of it for legacy and ACPI enumeration. Cc: H.

2020-02-12drm: Add support for extracting sync signal drive edge from videomodePeter Ujfalusi
The sync in some panels needs to be driven by different edge of the pixel clock compared to data. This is reflected by the DISPLAY_FLAGS_SYNC_(POS|NEG)EDGE in videmode flags. Add similar similar definitions for bus_flags and convert the sync drive edge via drm_bus_flags_from_videomode().

drm_atomic_helper_setup_commit expects that flipping of previous commits has happened when it is called to set up a new commit. This can be violated by commits where userspace doesn't get a flip completion event to synchronize against i.e. legacy modesets and property changes. The expectation is that those are done by blocking commits, which wait for completion. Most drivers call drm_atomic_helper_wait_for_vblanks in the commit_tail to ensure completion, but the wait for next vblank might not actually happen if the commit didn't change any planes. Make the wait more agressive by also waiting if no planes changed. This is the minimal regression fix for the 4.15 kernel series. Long term drivers should switch away from drm_atomic_helper_wait_for_vblanks and use drm_atomic_helper_wait_for_flip_done instead.

2020-02-12drm/vblank: Allow dynamic per-crtc max_vblank_countVille Syrjälä
On i965gm we need to adjust max_vblank_count dynamically depending on whether the TV encoder is used or not. To that end add a per-crtc max_vblank_count that takes precedence over its device wide counterpart. The driver can now call drm_crtc_set_max_vblank_count() to configure the per-crtc value before calling drm_vblank_on(). Also looks like there was some discussion about exynos needing similar treatment. v2: Drop the extra max_vblank_count!=0 check for the WARN(last!=current), will take care of it in i915 code (Daniel) WARN_ON(!inmodeset) (Daniel) WARN_ON(dev->max_vblank_count) Pimp up the docs (Daniel) Cc: stable@vger.kernel.org Cc: Inki Dae <inki.dae@samsung.com> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181127182004.28885-1-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>
