2020-06-20drm/panel-simple: Add missing connector type for some panelsDmitry Osipenko1-0/+7
The DRM panel bridge core requires connector type to be set up properly, otherwise it rejects the panel. The missing connector type problem popped up while I was trying to wrap CLAA070WP03XG panel into a DRM bridge in order to test whether panel's rotation property work properly using panel-simple driver on NVIDIA Tegra30 Nexus 7 tablet device, which uses CLAA070WP03XG display panel. The NVIDIA Tegra DRM driver recently gained DRM bridges support for the RGB output and now driver wraps directly-connected panels into DRM bridge. Hence all panels should have connector type set properly now, otherwise the panel's wrapping fails.

2020-05-09drm/panel-simple: Support hpd-gpios for delaying prepare()Douglas Anderson1-0/+53
People use panel-simple when they have panels that are builtin to their device. In these cases the HPD (Hot Plug Detect) signal isn't really used for hotplugging devices but instead is used for power sequencing. Panel timing diagrams (especially for eDP panels) usually have the HPD signal in them and it acts as an indicator that the panel is ready for us to talk to it. Sometimes the HPD signal is hooked up to a normal GPIO on a system. In this case we need to poll it in the correct place to know that the panel is ready for us. In some system designs the right place for this is panel-simple. When adding this support, we'll account for the case that there might be a circular dependency between panel-simple and the provider of the GPIO. The case this was designed for was for the "ti-sn65dsi86" bridge chip. If HPD is hooked up to one of the GPIOs provided by the bridge chip then in our probe function we'll always get back -EPROBE_DEFER. Let's handle this by allowing this GPIO to show up late if we saw -EPROBE_DEFER during probe. NOTE: since the gpio_get_optional() is used, if the "hpd-gpios" isn't there our variable will just be NULL and we won't do anything in prepare().

2020-02-29drm/panel: simple: add panel-dpi supportSam Ravnborg1-2/+72
The panel-dpi compatible is a fallback that allows the DT to specify the timing. When matching panel-dpi expect the device tree to include the timing information for the display-panel. Background for this change: There are a lot of panels and new models hits the market very often. It is a lost cause trying to chase them all and users of new panels will often find them in situations that the panel they ues are not supported by the kernel. On top of this a lot of panels are customized based on customer specifications. Including the panel timing in the device tree allows for a simple way to describe the actual HW and use this description in a generic way in the kernel. This allows uses of proprietary panels, or panels which are not included in the kernel, to specify the timing in the device tree together with all the other HW descriptions. And thus, using the device tree it is then easy to add support for an otherwise unknown panel. The current support expect panels that do not require any delays for prepare/enable/disable/unprepare.

2020-02-22drm/panel: simple: fix osd070t1718_19ts sync drive edgeTomi Valkeinen1-1/+2
The panel datasheet says that the panel samples at falling edge, but does not say anything about h/v sync signals. Testing shows that if the sync signals are driven on falling edge, the picture on the panel will be slightly shifted right. Setting sync drive edge to the same as data drive edge fixes this issue.

2019-12-09drm/panel: drop drm_device from drm_panelSam Ravnborg1-9/+7
The panel drivers used drm_panel.drm for two purposes: 1) Argument to drm_mode_duplicate() 2) drm->dev was used in error messages The first usage is replaced with drm_connector.dev - drm_connector is already connected to a drm_device and we have a valid connector The second usage is replaced with drm_panel.dev - this makes drivers more consistent in their dev argument used for dev_err() and friends With these replacements there are no more uses of drm_panel.drm, so it is removed from struct drm_panel. With this change drm_panel_attach() and drm_panel_detach() no longer have any use as they are empty functions. v2: - editorial correction in changelog (Laurent) Signed-off-by: Sam Ravnborg <[email protected]> Reviewed-by: Laurent Pinchart <[email protected]> Reviewed-by: Linus Walleij <[email protected]> Cc: Thierry Reding <[email protected]> Cc: Laurent Pinchart <[email protected]> Cc: Sam Ravnborg <[email protected]> Cc: Maarten Lankhorst <[email protected]> Cc: Maxime Ripard <[email protected]> Cc: David Airlie <[email protected]> Cc: Daniel Vetter <[email protected]> Cc: Linus Walleij <[email protected]> Cc: Jagan Teki <[email protected]> Cc: Stefan Mavrodiev <[email protected]> Cc: Robert Chiras <[email protected]> Cc: "Guido Günther" <[email protected]> Cc: Purism Kernel Team <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
