For maintaining consistency with kernel coding style replace reference/unreference in ref counting functions with get/put. The following cocci script was used to generate the tilcdc patch: @@ expression ex; @@ ( -drm_framebuffer_unreference(ex); +drm_framebuffer_put(ex); | -drm_dev_unref(ex); +drm_dev_put(ex); | -drm_framebuffer_reference(ex); +drm_framebuffer_get(ex); ) Signed-off-by:

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:

When we want to make drm_atomic_commit interruptible, there are a lot of places that call the lock function, which we don't have control over. Rather than trying to convert every single one, it's easier to toggle interruptible waiting per acquire_ctx. If drm_modeset_acquire_init is called with DRM_MODESET_ACQUIRE_INTERRUPTIBLE, then we will perform interruptible waits in drm_modeset_lock and drm_modeset_backoff. Changes since v1: - Fix locking example in drm_modeset_lock.c to be compatible with interruptible waiting (xexaxo) and make it default. Uninterruptible waiting shouldn't happen except in corner cases, but the example will still apply if the flag is removed. - Add drm_modeset_lock_single_interruptible() to documentation. - Fix dead link to removed drm_modeset_lock_interruptible() in drm_modeset_lock().

The POWER_DOWN_PHY and POWER_UP_PHY sideband message transactions allow the source to reqest any node in a mst path or a whole path to be powered down or up. This allows drivers to target a specific sink in the MST topology, an improvement over just power managing the imediate downstream device. Secondly, since the request-reply protocol waits for an ACK, we can be sure that a downstream sink has enough time to respond to a power up/down request. v2: Fix memory leak (Lyude) Cc: Lyude <lyude@redhat.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Harry Wentland <harry.wentland@amd.com> Signed-off-by:

The old codebase has a delay between enabling and powering up the PL11x. According to the manual for PL110, ARM DDI 0161E page 1-5 and the PL111 manual ARM DDI 0293C page 1-6, the power sequence should be such that once Vdd is stable (which we assume it is at boot) LCDEN is enabled first and then CLPOWER should be enabled "after the signals have stabilized" and this is said to be display-dependent. The old codebase uses 20ms. Reviewed-by:

We detect and enable the use of the PL110 variant, an earlier incarnation of PL111. The only real difference is that the control and interrupt enable registers have swapped place. The Versatile AB and Versatile PB have a variant inbetween PL110 and PL111, it is PL110 but they have already swapped the two registers so those two need a bit of special handling. Reviewed-by:

This replaces the custom connector in the PL111 with the panel bridge helper. This works nicely for all standard panels, but since there are several PL11x-based systems that will need to use the dumb VGA connector bridge we use drm_of_find_panel_or_bridge() and make some headroom for dealing with bridges that are not panels as well, and drop a TODO in the code.
