* drm/connector: Split out orientation quirk detection (v2)Derek Basehore2020-01-111-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Not every platform needs quirk detection for panel orientation, so split the drm_connector_init_panel_orientation_property into two functions. One for platforms without the need for quirks, and the other for platforms that need quirks. Hans de Goede (changes in v2): Rename the function from drm_connector_init_panel_orientation_property to drm_connector_set_panel_orientation[_with_quirk] and pass in the panel-orientation to set. Beside the rename, also make the function set the passed in value only once, if the value was set before (to a value other then DRM_MODE_PANEL_ORIENTATION_UNKNOWN) make any further set calls a no-op. This change is preparation for allowing the user to override the panel-orientation for any connector from the kernel commandline. When the panel-orientation is overridden this way, then we must ignore the panel-orientation detection done by the driver.

| | | | | | | | | | | | | | | TTM is an implementation detail of the VRAM helpers and therefore shouldn't be exposed to the callers.

* drm/bridge: Add the necessary bits to support bus format negotiationBoris Brezillon2020-01-071-0/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | drm_bridge_state is extended to describe the input and output bus configurations. These bus configurations are exposed through the drm_bus_cfg struct which encodes the configuration of a physical bus between two components in an output pipeline, usually between two bridges, an encoder and a bridge, or a bridge and a connector. The bus configuration is stored in drm_bridge_state separately for the input and output buses, as seen from the point of view of each bridge. The bus configuration of a bridge output is usually identical to the configuration of the next bridge's input, but may differ if the signals are modified between the two bridges, for instance by an inverter on the board. The input and output configurations of a bridge may differ if the bridge modifies the signals internally, for instance by performing format conversion, or*modifying signals polarities. Bus format negotiation is automated by the core, drivers just have to implement the ->atomic_get_{output,input}_bus_fmts() hooks if they want to take part to this negotiation. Negotiation happens in reverse order, starting from the last element of the chain (the one directly connected to the display) up to the first element of the chain (the one connected to the encoder). During this negotiation all supported formats are tested until we find one that works, meaning that the formats array should be in decreasing preference order (assuming the driver has a preference order). Note that the bus format negotiation works even if some elements in the chain don't implement the ->atomic_get_{output,input}_bus_fmts() hooks. In that case, the core advertises only MEDIA_BUS_FMT_FIXED and lets the previous bridge element decide what to do (most of the time, bridge drivers will pick a default bus format or extract this piece of information from somewhere else, like a FW property).

These would be preferred over the drm printk and struct device based macros in drm code, where possible. We have existing drm specific struct device based logging functions, but they are too verbose to use for two main reasons: * The names are unnecessarily long, for example DRM_DEV_DEBUG_KMS(). * The use of struct device over struct drm_device is too generic for most users, leading to an extra dereference. For example: DRM_DEV_DEBUG_KMS(drm->dev, "Hello, world\n"); vs. drm_dbg_kms(drm, "Hello, world\n"); It's a matter of taste, but the SHOUTING UPPERCASE has been argued to be less readable than lowercase. Some names are changed from old DRM names to be based on the core kernel logging functions. For example, NOTE -> notice, ERROR -> err, DEBUG -> dbg. Due to the conflation of DRM_DEBUG and DRM_DEBUG_DRIVER macro use (DRM_DEBUG is used widely in drivers though it's supposed to be a core debugging category), they are named as drm_dbg_core and drm_dbg, respectively. The drm_err and _once/_ratelimited variants no longer include the function name in order to be able to use the core device based logging macros. Arguably this is not a significant change; error messages should not be so common to be only distinguishable by the function name. Ratelimited debug logging macros are to be added later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes we want to override a connector's panel_orientation from the kernel commandline. Either for testing and for special cases, e.g. a kiosk like setup which uses a TV mounted in portrait mode. Users can already specify a "rotate" option through a video= kernel cmdline option. But that only supports 0/180 degrees (see drm_client_modeset TODO) and only works for in kernel modeset clients, not for userspace kms users. The "panel-orientation" connector property OTOH does support 90/270 degrees as it leaves dealing with the rotation up to userspace and this does work for userspace kms clients (at least those which support this property).

The device tree can be used to fully describe dual-link LVDS connections between encoders and bridges/panels. The sink of an LVDS dual-link connection is made of two ports, the corresponding OF graph port nodes can be marked with either dual-lvds-even-pixels or dual-lvds-odd-pixels, and that fully describes an LVDS dual-link connection, including pixel order. drm_of_lvds_get_dual_link_pixel_order is a new helper added by this patch, given the source port nodes it returns DRM_LVDS_DUAL_LINK_EVEN_ODD_PIXELS if the source port nodes belong to an LVDS dual-link connection, with even pixels expected to be generated from the first port, and odd pixels expected to be generated from the second port. If the new helper returns DRM_LVDS_DUAL_LINK_ODD_EVEN_PIXELS, odd pixels are expected to be generated from the first port, and even pixels from the other port.

This patch adds a connector argument to drm_panel_get_modes(). All users of drm_panel_get_modes() already had the connector available, so updating users was trivial. With this patch drm_panel no longer keeps a reference to the drm_connector.

Update the drm_panel infrastructure to support this to simplify the drivers. With this the panel driver just needs to add the following to the probe() function: err = drm_panel_of_backlight(panel); if (err) return err; Then drm_panel will handle all the rest. There is one caveat with the backlight support. If drm_panel_(enable|disable) are called multiple times in a row then backlight_(enable|disable) will be called multiple times. The above will happen when a panel drivers unconditionally calls drm_panel_disable() in their shutdown() function, whan the panel is already disabled and then shutdown() is called. Reading the backlight code it seems safe to call the backlight_(enable|disable) several times. v3: - Improve comments, fix grammar (Laurent) - Do not fail in drm_panel_of_backlight() if no DT support (Laurent) - Log if backlight_(enable|disable) fails (Laurent) - Improve drm_panel_of_backlight() docs - Updated changelog with backlight analysis (triggered by Laurent) v2: - Drop test of CONFIG_DRM_PANEL in header-file (Laurent) - do not enable backlight if ->enable() returns an error Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <maxime.ripard@bootlin.com> Cc: Sean Paul <sean@poorly.run> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20191207140353.23967-3-sam@ravnborg.org

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.
