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
