This is something that we've wanted for a while now: the ability to actually look up the respective drm_device for a given drm_dp_aux struct. This will also allow us to transition over to using the drm_dbg_*() helpers for debug message printing, as we'll finally have a drm_device to reference for doing so. Note that there is one limitation with this - because some DP AUX adapters exist as platform devices which are initialized independently of their respective DRM devices, one cannot rely on drm_dp_aux->drm_dev to always be non-NULL until drm_dp_aux_register() has been called.

2020-02-26drm/bridge: Extend bridge API to disable connector creationLaurent Pinchart2-2/+2
Most bridge drivers create a DRM connector to model the connector at the output of the bridge. This model is historical and has worked pretty well so far, but causes several issues: - It prevents supporting more complex display pipelines where DRM connector operations are split over multiple components. For instance a pipeline with a bridge connected to the DDC signals to read EDID data, and another one connected to the HPD signal to detect connection and disconnection, will not be possible to support through this model. - It requires every bridge driver to implement similar connector handling code, resulting in code duplication. - It assumes that a bridge will either be wired to a connector or to another bridge, but doesn't support bridges that can be used in both positions very well (although there is some ad-hoc support for this in the analogix_dp bridge driver). In order to solve these issues, ownership of the connector should be moved to the display controller driver (where it can be implemented using helpers provided by the core). Extend the bridge API to allow disabling connector creation in bridge drivers as a first step towards the new model. The new flags argument to the bridge .attach() operation allows instructing the bridge driver to skip creating a connector. Unconditionally set the new flags argument to 0 for now to keep the existing behaviour, and modify all existing bridge drivers to return an error when connector creation is not requested as they don't support this feature yet. The change is based on the following semantic patch, with manual review and edits. @ rule1 @ identifier funcs; identifier fn; @@ struct drm_bridge_funcs funcs = { ..., .attach = fn }; @ depends on rule1 @ identifier rule1.fn; identifier bridge; statement S, S1; @@ int fn( struct drm_bridge *bridge + , enum drm_bridge_attach_flags flags ) { ... when != S + if (flags & DRM_BRIDGE_ATTACH_NO_CONNECTOR) { + DRM_ERROR("Fix bridge driver to make connector optional!"); + return -EINVAL; + } + S1 ... } @ depends on rule1 @ identifier rule1.fn; identifier bridge, flags; expression E1, E2, E3; @@ int fn( struct drm_bridge *bridge, enum drm_bridge_attach_flags flags ) { <... drm_bridge_attach(E1, E2, E3 + , flags ) ...> } @@ expression E1, E2, E3; @@ drm_bridge_attach(E1, E2, E3 + , 0 ) Signed-off-by: Laurent Pinchart <[email protected]> Reviewed-by: Boris Brezillon <[email protected]> Acked-by: Sam Ravnborg <[email protected]> Reviewed-by: Tomi Valkeinen <[email protected]> Tested-by: Sebastian Reichel <[email protected]> Reviewed-by: Sebastian Reichel <[email protected]> Acked-by: Daniel Vetter <[email protected]> Signed-off-by: Tomi Valkeinen <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2019-12-09drm: Stop accessing encoder->bridge directlyBoris Brezillon1-2/+8
We are about to replace the single-linked bridge list by a double-linked one based on list.h, leading to the suppression of the encoder->bridge field. But before we can do that we must provide a drm_bridge_chain_get_first_bridge() bridge helper and patch all drivers and core helpers to use it instead of directly accessing encoder->bridge. Note that we still have 2 drivers (VC4 and Exynos) manipulating the encoder->bridge field directly because they need to cut the bridge chain in order to control the enable/disable sequence. This is definitely not something we want to encourage, so let's keep those 2 oddities around until we find a better solution.

2016-06-09drm: msm: Rely on the default ->best_encoder() behavior where appropriateBoris Brezillon1-10/+0
For all outputs except DSI we have a 1:1 relationship between connectors and encoders and the driver is relying on the atomic helpers: we can drop the custom ->best_encoder() and let the core call drm_atomic_helper_best_encoder() for us.

2016-05-08drm/msm: Centralize connector registration/unregistrationArchit Taneja1-16/+4
Move the drm_connector registration from the encoder(HDMI/DSI etc) drivers to the msm platform driver. This will simplify the task of ensuring that the connectors are registered only after the drm_device itself is registered. The connectors' destroy ops are made to use kzalloc instead of devm_kzalloc to ensure that that the connectors can be successfully unregistered when the msm driver module is removed. The memory for the connectors is unallocated when drm_mode_config_cleanup() is called during either during an error or during driver remove.

2016-05-08drm/msm/edp: Drop regulator_set_voltage callArchit Taneja1-9/+1
The eDP driver tries to set a fixed voltage for one of its regulators(vdda) before enabling it. This shouldn't be done by the driver, the voltage constraints should be specified on the regulator via DT and managed by the regulator core. A driver should call regulator_set_voltage only if it needs to change the voltage during runtime. Drop the regulator_set_voltage call. Mention in a comment the voltage that the regulator expects.

2016-05-08drm/msm: Move call to PTR_ERR_OR_ZERO after reassignmentVaishali Thakkar1-8/+11
Here, a location is reset to NULL before being passed to PTR_ERR. So, PTR_ERR should be called before its argument is reassigned to NULL. Further to simplify things use PTR_ERR_OR_ZERO instead of PTR_ERR and IS_ERR. Problem found using Coccinelle.

2015-08-15drm/msm/dp: use flags argument of devm_gpiod_get to set directionUwe Kleine-König1-15/+2
Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Use this to simplify the driver. Furthermore this is one caller less that stops us making the flags argument to gpiod_get*() mandatory.

2015-06-11drm/msm: drop redundant debug outputNicholas Mc Guire1-2/+1
wait_for_completion_timeout returns 0 in case of timeout and never return < 0 so there is no additional information in printing the value of time_left here as it will always be 0, thus it can be dropped.

2015-06-11drm/msm: wait_for_completion_timeout return is never negativeNicholas Mc Guire1-1/+1
wait_for_completion_timeout returns >= 0 but never negative - so the error check should be against equality to 0 not <= 0. Signed-off-by: Nicholas Mc Guire <[email protected]> Signed-off-by: Rob Clark <[email protected]>
2015-06-11drm/msm: match wait_for_completion_timeout return typeNicholas Mc Guire1-5/+5

2015-06-11drm/msm: drop redundant output in debug messageNicholas Mc Guire1-1/+1
wait_for_completion_timeout returns 0 in case of timeout so printing the return value here will always yield 0 and is therefor redundant - dropped. Signed-off-by: Nicholas Mc Guire <[email protected]> Signed-off-by: Rob Clark <[email protected]>
2015-06-11drm/msm: fix HZ dependency of timeoutNicholas Mc Guire1-1/+2
The timeout is passed as a constant which makes it HZ dependent because jiffies are expected so it should be converted to jiffies. The actual value is not clear from the code - my best guess is that this should be 300 milliseconds given that other timeouts are in milliseconds based on looking at other drm drivers (e.g. exynos_drm_dsi.c:356 300ms, tegra/dpaux.c:188 250ms) - this needs to be confirmed by someone who knows the details of the driver.

2015-06-11drm/msm: fixup wait_for_completion_timeout handlingNicholas Mc Guire1-3/+5
wait_for_completion_timeout return >= 0 but never negative so the check logic looks inconsistent. Further the return value of wait_for_completion_timeout was being passed up the call chain but the x call sites as drm_dp_i2c_do_msg()/drm_dp_dpcd_access() check for < 0 thus timeout was being treated as success case. <snip> drivers/gpu/drm/drm_dp_helper.c:drm_dp_i2c_do_msg() mutex_lock(&aux->hw_mutex); ret = aux->transfer(aux, msg); mutex_unlock(&aux->hw_mutex); if (ret < 0) { <snip> logic in edp_aux_transfer() seems incorrect as it could return 0 (timeout) but checks of <= 0 to indicate error so the return probably should be -ETIMEDOUT in case wait_for_completion_timeout returns 0 (timeout occurred).
