2017-11-20drm: Check crtc_state->enable rather than crtc->enabled in ↵Ville Syrjälä14-38/+50
drm_plane_helper_check_state() drm_plane_helper_check_state() is supposed to do things the atomic way, so it should not be inspecting crtc->enabled. Rather we should be looking at crtc_state->enable. We have a slight complication due to drm_plane_helper_check_update() reusing drm_plane_helper_check_state() for non-atomic drivers. Thus we'll have to pass the crtc_state in manally and construct a fake crtc_state in drm_plane_helper_check_update(). v2: Fix the WARNs about plane_state->crtc matching crtc_state->crtc Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171101201558.6059-1-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>

There is no need to #define the license of the driver, just put it in the MODULE_LICENSE() line directly as a text string. This allows tools that check that the module license matches the source code license to work properly, as there is no need to unwind the unneeded dereference, especially when the string is defined in a .h file far away from the .c file it is used in.

The i2c adapter on DP AUX is purely a software construct. Linking it to the device node of the parent device is wrong, as it leads to 2 devices sharing the same device node, which is bad practice, as well as the i2c trying to populate children of the i2c adapter by looking at the child device nodes of the parent device.

2017-11-08drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2.Maarten Lankhorst1-6/+17
This introduces a slight behavioral change to rmfb. Instead of disabling a crtc when the primary plane is disabled, we try to preserve it. Apart from old versions of the vmwgfx xorg driver, there is nothing depending on rmfb disabling a crtc. Vmwgfx' and simple kms helper atomic implementation rejects CRTC enabled without plane, so we can do this safely. If the atomic commit is rejected by the driver then we will still fall back to the old behavior and turn off the crtc. Changes since v1: - Restart completely when rmfb with crtc on fails (Sean Paul).

2017-11-07drm/edid: set ELD connector type in drm_edid_to_eld()Jani Nikula1-2/+7
Since drm_edid_to_eld() knows the connector type, we can set the type in ELD while at it. Most connectors this gets called on are not DP encoders, and with the HDMI type being 0, this does not change behaviour for non-DP. For i915 having this in place earlier would have saved a considerable amount of debugging that lead to the fix 2d8f63297b9f ("drm/i915: always update ELD connector type after get modes"). I don't see other drivers, even the ones calling drm_edid_to_eld() on DP connectors, setting the connector type in ELD.

2017-11-06drm: via: use ktime_get() instead of do_gettimeofdayArnd Bergmann2-16/+9
We want to remove uses of do_gettimeofday() from the kernel since the resulting timeval structure overflows in 2038. This is not a problem for this particular use, but do_gettimeofday() is also not an appropriate method for measuring time intervals, since it requires a conversion into microseconds and is complicated to work with. ktime_get() is a better replacement, as it works with the monontonic kernel timebase and requires a minimum of computation. I'm slightly changing the output from microseconds to nanoseconds here, to avoid introducing a new division operation. This should be fine since the value is only used for debugging.
