2020-06-10drm/tve200: Use GEM CMA object functionsThomas Zimmermann
Create GEM objects with drm_gem_cma_create_object_default_funcs(), which allocates the object and sets CMA's default object functions. Corresponding callbacks in struct drm_driver are cleared. No functional changes are made. Driver and object-function instances use the same callback functions, with the exception of vunmap.

2019-12-09drm: get drm_bridge_panel connector via helperSam Ravnborg
The drm_connector created by drm_panel_bridge was accessed via drm_panel.connector. Avoid the detour around drm_panel by providing a simple get method. This avoids direct access to the connector field in drm_panel in the two users. The change is done in preparation for removal of drm_panel.connector. Update pl111 and tve200 to use the new helper.

2019-09-08drm/bridge: panel: Infer connector type from panel by defaultLaurent Pinchart
The drm panel bridge creates a connector using a connector type explicitly passed by the display controller or bridge driver that instantiates the panel bridge. Now that drm_panel reports its connector type, we can use it to avoid passing an explicit (and often incorrect) connector type to drm_panel_bridge_add() and devm_drm_panel_bridge_add(). Several drivers report incorrect or unknown connector types to userspace. Reporting a different type may result in a breakage. For that reason, rename (devm_)drm_panel_bridge_add() to (devm_)drm_panel_bridge_add_typed(), and add new (devm_)drm_panel_bridge_add() functions that use the panel connector type. Update all callers of (devm_)drm_panel_bridge_add() to the _typed function, they will be converted one by one after testing. The panel drivers have been updated with the following Coccinelle semantic patch, with manual inspection and fixes to indentation. @@ expression bridge; expression dev; expression panel; identifier type; @@ ( -bridge = drm_panel_bridge_add(panel, type); +bridge = drm_panel_bridge_add_typed(panel, type); | -bridge = devm_drm_panel_bridge_add(dev, panel, type); +bridge = devm_drm_panel_bridge_add_typed(dev, panel, type); ) Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190904132804.29680-3-laurent.pinchart@ideasonboard.com

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

2018-09-25drm/tve200: Use drm_fbdev_generic_setup()Noralf Trønnes
The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing.

2017-08-23drm/tve200: Add new driver for TVE200Linus Walleij
This adds a new DRM driver for the Faraday Technology TVE200 block. This "TV Encoder" encodes a ITU-T BT.656 stream and can be found in the StorLink SL3516 (later Cortina Systems CS3516) as well as the Grain Media GM8180. I do not have definitive word from anyone at Faraday that this IP block is theirs, but it bears the hallmark of their 3-digit version code (200) and is used in two SoCs from completely different companies. (Grain Media was fully owned by Faraday until it was transferred to NovoTek this january, and Faraday did lots of work on the StorLink SoCs.) The D-Link DIR-685 uses this in connection with the Ilitek ILI9322 panel driver that supports BT.656 input, while the GM8180 apparently has been used with the Cirrus Logic CS4954 digital video encoder. The oldest user seems to be something called Techwall 2835. This driver is heavily inspired by Eric Anholt's PL111 driver and therefore I have mentioned all the ancestor authors in the header file.
