| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make sti driver use register callback to move debugfs initialization out of sub-components creation. This will allow to convert driver .load() to drm_dev_alloc() and drm_dev_register(). sti_compositor bring up 2 crtc but only one debugfs init is needed so use drm_crtc_index to do it on the first one. This can't be done in sti_drv because only sti_compositor have access to the devices. It is almost the same for sti_encoder which handle multiple encoder while one only debugfs entry is needed so add a boolean to avoid multiple debugfs initialization Signed-off-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1466514580-15194-3-git-send-email-benjamin.gaignard@linaro.org

* drm/bridge: make bridge registration independent of drm flowAjay Kumar2015-01-281-9/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, third party bridge drivers(ptn3460) are dependent on the corresponding encoder driver init, since bridge driver needs a drm_device pointer to finish drm initializations. The encoder driver passes the drm_device pointer to the bridge driver. Because of this dependency, third party drivers like ptn3460 doesn't adhere to the driver model. In this patch, we reframe the bridge registration framework so that bridge initialization is split into 2 steps, and bridge registration happens independent of drm flow: --Step 1: gather all the bridge settings independent of drm and add the bridge onto a global list of bridges. --Step 2: when the encoder driver is probed, call drm_bridge_attach for the corresponding bridge so that the bridge receives drm_device pointer and continues with connector and other drm initializations. The old set of bridge helpers are removed, and a set of new helpers are added to accomplish the 2 step initialization. The bridge devices register themselves onto global list of bridges when they get probed by calling "drm_bridge_add". The parent encoder driver waits till the bridge is available in the lookup table(by calling "of_drm_find_bridge") and then continues with its initialization. The encoder driver should also call "drm_bridge_attach" to pass on the drm_device to the bridge object. drm_bridge_attach inturn calls "bridge->funcs->attach" so that bridge can continue with drm related initializations.
