drm/sysfs: fix hotplug regression since lifetime changes

2013-11-21T11:10:00Z

airlied: The lifetime changes introduced in 5bdebb183c9702a8c57a01dff09337be3de337a6 tried to use device_create, however that led to the regression where dev->type wasn't getting set correctly. First attempt at fixing it would have led to a race, so this undoes the device_createa work and does it all manually making sure the dev->type is setup before we register the device.

drm/sysfs: Remove stale comments about calling drm_sysfs_connector_add() multiple times

2013-11-06T03:41:37Z

drm_connector_sysfs_add() explicitly checks if connector->kdev is already populated and returns success. So it clearly now allows being called multiple times. Remove some stale comments to the contrary. Signed-off-by: Ville Syrjälä Reviewed-by: Jani Nikula Signed-off-by: Dave Airlie

drm/sysfs: Do not drop device reference twice

2013-10-30T20:33:49Z

device_unregister() already drops its reference to the struct device, so explicitly calling put_device() before device_unregister() can cause the device to have been freed before it can be unregistered.

drm/sysfs: sort out minor and connector device object lifetimes.

2013-10-22T08:37:40Z

So drm was abusing device lifetimes, by having embedded device structures in the minor and connector it meant that the lifetime of the internal drm objects (drm_minor and drm_connector) were tied to the lifetime of the device files in sysfs, so if something kept those files opened the current code would kfree the objects and things would go downhill from there. Now in reality there is no need for these lifetimes to be so intertwined, especailly with hotplugging of devices where we wish to remove the sysfs and userspace facing pieces before we can unwind the internal objects due to open userspace files or mmaps, so split the objects out so the struct device is no longer embedded and do what fbdev does and just allocate and remove the sysfs inodes separately.

drm: Convert drm class driver from legacy pm ops to dev_pm_ops

2013-07-04T00:50:26Z

Convert drivers/gpu/drm class to use dev_pm_ops for power management and remove Legacy PM ops hooks. With this change, drm class registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy class->suspend/resume. When __device_suspend() runs call-backs, it will find class->pm ops for the drm class. drm_class_suspend() hook calls driver legacy ops with the state information. e.g: drm_class_suspend() calls into driver suspend routines via drm_dev->driver->suspend(drm_dev, state). Once drm_class_suspend() is converted to dev_pm_ops, it will no longer have access to pm_transition which it has to pass into driver legacy suspend calls. A new freeze and suspend hooks are added to address the not having access to the state information. The new freeze and suspend hooks simply call __drm_class_suspend() with the appropriate pm state information. __drm_class_suspend() is the original suspend hook with a new name.

drm: remove legacy drm_connector_property fxns

Replace references to and remove the connector property fxns, which have been superseded with the more general object property fxns: + drm_connector_attach_property -> drm_object_attach_property + drm_connector_property_set_value -> drm_object_property_set_value + drm_connector_property_get_value -> drm_object_property_get_value Signed-off-by: Rob Clark

drm: fail gracefully when proc isn't setup.
