drm: Remove duplicate forward declaration

2017-06-15T01:25:17+00:00

Forward declarations in C are great but I'm pretty sure one is enough. Signed-off-by: Dawid Kurek Signed-off-by: Sean Paul Link: http://patchwork.freedesktop.org/patch/msgid/20170614213518.GA3554@gmail.com

drm: remove unsafe drm_for_each_connector()

2017-05-26T05:13:13+00:00

After converting all users to drm_for_each_connector_iter() we no longer need drm_for_each_connector() so we can go ahead and remove it. Signed-off-by: Gustavo Padovan Reviewed-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20170511191049.28944-8-gustavo@padovan.org

drm: trivial documentation fix to drm_for_each_connector_iter

2017-05-18T05:57:32+00:00

While reading drm_for_each_connector_iter, I noticed a mention to drm_connector_begin which doesn't exist. It should be drm_connector_get.

drm/atomic: Add support for custom scaling mode properties, v2

2017-05-08T11:20:43+00:00

Some connectors may not allow all scaling mode properties, this function will allow creating the scaling mode property with only the supported subset. It also wires up this state for atomic. This will make it possible to convert i915 connectors to atomic. Changes since v1: - Add DRM_MODE_PROP_ENUM flag to drm_property_create - Use the correct index in drm_property_add_enum. - Add DocBook for function (Sean Paul). - Warn if less than 2 valid scaling modes are passed. - Remove level of indent.

drm/atomic: Handle picture_aspect_ratio in atomic core

2017-05-08T11:20:31+00:00

This is only used in i915, which had used its own non-atomic way to deal with the picture aspect ratio. Move selected aspect_ratio to atomic state and use the atomic state in the affected i915 connectors.

drm/atomic: Acquire connection_mutex lock in drm_helper_probe_single_connector_modes, v4.

2017-04-06T19:29:23+00:00

mode_valid() called from drm_helper_probe_single_connector_modes() may need to look at connector->state because what a valid mode is may depend on connector properties being set. For example some HDMI modes might be rejected when a connector property forces the connector into DVI mode. Some implementations of detect() already lock all state, so we have to pass an acquire_ctx to them to prevent a deadlock. This means changing the function signature of detect() slightly, and passing the acquire_ctx for locking multiple crtc's. For the callbacks, it will always be non-zero. To allow callers not to worry about this, drm_helper_probe_detect_ctx is added which might handle -EDEADLK for you. Changes since v1: - Always set ctx parameter. Changes since v2: - Always take connection_mutex when probing. Changes since v3: - Remove the ctx from intel_dp_long_pulse, and add WARN_ON(!connection_mutex) (danvet) - Update docs to clarify the locking situation.

drm: Add data transmission order bus flag

2017-04-04T14:03:30+00:00

The flags indicate whether data is transmitted LSB to MSB or MSB to LSB on the bus. The exact meaning is bus-type dependent. For instance, for LVDS buses the flags indicate whether the seven data bits transmitted in a clock pulse are sent in normal order (MSB to LSB, slots 0 to 6) or reverse order (LSB to MSB, slots 6 to 0).

The rules are getting real hard, better to dump my brain into text a bit. This is by far not complete, but I think I reasonable start at least.
