Merge branch 'drm-docs' of ssh://people.freedesktop.org/~danvet/drm into drm-next
Here's my drm documentation update and driver api polish pull request. Alex reviewed the entire pile, I've applied a little bit of spelling polish in a few places since then and otherwise the Usual Suspects (David, Rob, ...) don't seem up to have another look at it (I've poked them on irc). So I think it's as good as it gets ;-) Note that I've dropped the final imx breaker patch since that's blocked on imx getting sane. Once that's landed I'll ping you to pick up that straggler. * 'drm-docs' of ssh://people.freedesktop.org/~danvet/drm: (34 commits) drm/imx: remove drm_mode_connector_detach_encoder harder drm: kerneldoc polish for drm_crtc.c drm: kerneldoc polish for drm_crtc_helper.c drm: drop error code for drm_helper_resume_force_mode drm/crtc-helper: remove LOCKING from kerneldoc drm: remove return value from drm_helper_mode_fill_fb_struct drm/doc: Fix misplaced </para> drm: remove drm_display_mode->private_size drm: polish function kerneldoc for drm_modes.[hc] drm/modes: drop maxPitch from drm_mode_validate_size drm/modes: drop return value from drm_display_mode_from_videomode drm/modes: remove drm_mode_height/width drm: extract drm_modes.h for drm_crtc.h functions drm: move drm_mode related functions into drm_modes.c drm/doc: Repleace LOCKING kerneldoc sections in drm_modes.c drm/doc: Integrate drm_modes.c kerneldoc drm/kms: rip out drm_mode_connector_detach_encoder drm/doc: Add function reference documentation for drm_mm.c drm/doc: Overview documentation for drm_mm.c drm/mm: Remove MM_UNUSED_TARGET ...
