If the new video=... panel_orientation option is set for a connector, honor it and setup a matching "panel orientation" property on the connector. Changes in v2: -Improve DRM_INFO message to make it clear that the panel_orientation is being forced from the commandline BugLink: https://gitlab.freedesktop.org/plymouth/plymouth/merge_requests/83Acked-by:

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. Reviewed-by:

The Allwinner SoCs have a display engine composed of several controllers assembled differently depending on the SoC, the number and type of output they have, and the additional features they provide. A number of those are supported in Linux, with the matching bindings. Now that we have the DT validation in place, let's split into separate file and convert the device tree bindings for those controllers to schemas. Reviewed-by:

The udl driver for DisplayLink devices depends on support for host-side USB controllers, which is enabled with CONFIG_USB. Plain USB support as given by CONFIG_USB_SUPPORT is not sufficient. This patch changes dependencies for udl to depend on CONFIG_USB, instead of CONFIG_USB_SUPPORT. Users will have to enable CONFIG_USB and select a USB host controller. With this change udl dependencies work the same way as dependencies for PCI drivers. Signed-off-by:

There is an increasing number of new simple panels. Common for many of these simple panels are that they have one mandatory power-supply and some of them have backlight and / or an enable gpio. The binding file to describe these panels adds overhead that really do not add value. The binding are known and there is nothing gained from a dedicated binding file nor for any dedicated example. The following patch introduces a single panel-simple.yaml and converts two ampire bindings over to the new file. The conversion - if applied will have following effects: - The maintainer for the individual file will change There is no need for many different maintainers for a simple binding. We have the same situation with the panel-simple driver in the kernel. - The license will change to (GPL-2.0-only OR BSD-2-Clause) There is usually only a single line copied from the original file, a line that is often copied from a datasheet. This license change should be acceptable considered what little is copied. If the license change is not OK we can use a dedicated binding file in these cases. This is a follow-up on Rob's big patch converting a lot of panel bindings to individual files: "dt-bindings: display: Convert a bunch of panels to DT schema" https://patchwork.ozlabs.org/patch/1197683/ The objectives with one file for the relevant simple panels are: - Make it simpler to add bindings for simple panels - Keep the number of bindings file lower and thus easier to find a relevant file to copy from when adding new panels. - Keep the binding documentation for simple panels more consistent - Make it simpler to add support for new panels v3: - Whitespace fix (checkpatch) - Indent compatible (Rob h) - Indent comments to give compatible more visibility (Rob h) v2: - spelling fixes (imirkin via irc, Rob) - updated description (Rob) - list properires in alphabetical order - added power-supply to example (Rob) - updated title - reworded changelog a little Signed-off-by: -

The DRC needs to run at 300MHz to be functional. This was done so far using assigned-clocks in the device tree, but that is easy to forget, and doesn't provide any other guarantee than the rate is going to be roughly the one requested at probe time. Therefore it's pretty fragile, so let's just use the exclusive clock API to enforce it. Reviewed-by:

Commit 05193dc3 ("drm/bridge: Make the bridge chain a double-linked list") patched the bridge chain logic to use a double-linked list instead of a single-linked list. This change induced changes to the Exynos driver which was manually resetting the encoder->bridge element to NULL to control the enable/disable sequence of the bridge chain. During this conversion, 2 bugs were introduced: 1/ list_splice() was used to move chain elements to our own internal chain, but list_splice() does not reset the source list to an empty state, leading to unexpected bridge hook calls when drm_bridge_chain_xxx() helpers were called by the core. Replacing the list_splice() call by list_splice_init() fixes this problem. 2/ drm_bridge_chain_xxx() helpers operate on the bridge->encoder->bridge_chain list, which is now empty. When the helper uses list_for_each_entry_reverse() we end up with no operation done which is not what we want. But that's even worse when the helper uses list_for_each_entry_from(), because in that case we end up in an infinite loop searching for the list head element which is no longer encoder->bridge_chain but exynos_dsi->bridge_chain. To address that problem we stop using the bridge chain helpers and call the hooks directly. Reported-by:
