We need the following things to happen in sequence: DSI host creation DSI device creation in the panel driver (needs DSI host) DSI device attach from panel to host. DSI drm_panel_add() DSI encoder creation DSI encoder's DRM panel/bridge attach Unless we allow device creation while the host isn't up yet, we need to break the -EPROBE_DEFER deadlock between the panel driver looking up the host and the host driver looking up the panel. We can do so by moving the DSI host creation outside of the component bind loop, and the panel/bridge lookup/attach into the component bind process. Signed-off-by:

The incoming mode might have a missing vrefresh field if it came from drmModeSetCrtc(), which the kernel is supposed to calculate using drm_mode_vrefresh(). We could either use that or the adjusted_mode's original vrefresh value. However, we can maintain a more exact vrefresh value (not just the integer approximation), by scaling by the ratio of our clocks. v2: Use math suggested by Andrzej Hajda instead. v3: Simplify math now that adjusted_mode->clock isn't padded. v4: Drop some parens.

Reference counting functions in the kernel typically use get/put suffixes. For maintaining coding style consistency, introduce drm_dev_{get/put} functions. All callers of drm_dev_ref() API have been converted in this patch and hence it has been dropped while the drm_dev_unref() API with non-trivial number of users remains for compatibility. The semantic patch scripts/coccinelle/api/drm-get-put.cocci has been updated with the new helper for conversion of drm_dev_unref() to drm_dev_put() Signed-off-by: -

Due to inconsistency of how various legacy drivers implemented DPMS the DPMS uabi has a lot of quirks. Atomic standardizes this, but drivers using the DPMS support can't rely on that since legacy drivers still exist. Laurent asked for this. v2: Improve commit message and explain that DPMS doesn't really exist for the atomic ioctl (it's "ACTIVE" on the CRTC instead). Text polish from Eric's review.

Handle debugfs override edid and firmware edid at the low level to transparently and completely replace the real edid. Previously, we practically only used the modes from the override EDID, and none of the other data, such as audio parameters. This change also prevents actual EDID reads when the EDID is to be overridden, but retains the DDC probe. This is useful if the reason for preferring override EDID are problems with reading the data, or corruption of the data. Move firmware EDID loading from helper to core, as the functionality moves to lower level as well. This will result in a change of module parameter from drm_kms_helper.edid_firmware to drm.edid_firmware, which arguably makes more sense anyway. Some future work remains related to override and firmware EDID validation. Like before, no validation is done for override EDID. The firmware EDID is validated separately in the loader. Some unification and deduplication would be in order, to validate all of them at the drm_do_get_edid() level, like "real" EDIDs. v2: move firmware loading to core v3: rebase, commit message refresh Cc: Abdiel Janulgue <abdiel.janulgue@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Tested-by:

The adv7511 driver keeps a private copy of the EDID in its driver state struct. But this copy is only used in adv7511_get_modes() where it is also retrieved, so there is no need to keep this extra copy around. If a need to access the EDID elsewhere in the driver ever arises the copy that is stored in the connector can be used. This copy is accessible through drm_connector_get_edid(). Note, this patch removes the NULL check of the EDID before passing it to drm_detect_hdmi_monitor(), but that is fine since the function correctly handles the case where the EDID is NULL.

Currently adv7511_get_modes() bails out early when no EDID could be retrieved. This leaves the previous EDID in place, which is typically not the intended behavior and might confuse applications. Instead the EDID should be cleared when no EDID could be retrieved. All functions that are called after the EDID check handle the case where the EDID is NULL just fine and exhibit the expected behavior, so just drop the check. Signed-off-by:
