2021-02-02amba: Make the remove callback return voidUwe Kleine-König
All amba drivers return 0 in their remove callback. Together with the driver core ignoring the return value anyhow, it doesn't make sense to return a value here. Change the remove prototype to return void, which makes it explicit that returning an error value doesn't work as expected. This simplifies changing the core remove callback to return void, too.

2020-11-09drm/cma-helper: Make default object functions the defaultThomas Zimmermann
As GEM object functions are now mandatory, DRM drivers based on CMA helpers either set them in their implementation of gem_create_object, or use the default via drm_gem_cma_create_object_default_funcs(). Simplify this by setting the default CMA object functions for all objects that don't have any functions of their own. Follows the pattern of similar code in SHMEM and VRAM helpers. The function drm_gem_cma_create_object_default_funcs() is redundant and therefore being removed.

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

Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a break from the middle of the loop there is no put, thus causing a memory leak. Hence add an of_node_put before the break. Issue found with Coccinelle.

The DRM_BUS_FLAG_PIXDATA_(POS|NEG)EDGE and DRM_BUS_FLAG_SYNC_(POS|NEG)EDGE flags are deprecated in favour of the new DRM_BUS_FLAG_PIXDATA_(DRIVE|SAMPLE)_(POS|NEG)EDGE and new DRM_BUS_FLAG_SYNC_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags. Replace them through the code. This effectively changes the value of the .sampling_edge bridge timings field in the dumb-vga-dac driver. This is safe to do as no driver consumes these values yet.

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/pl111: 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.

The Nomadik has a variant of the PL110 known as "Color LCD Controller" LCDC. This variant has the same bit ordering as the DRM subsystem (in difference from the other variants) and adds a few bits for the control of 5551, 565 etc in the control register. Notably it also adds a packed RGB888 24BPP mode. We add support by detecting this variant and also adding a small plug-in that will mux the LCDC out if the ASIC happens to be muxed to the other graphics controller (they are mutually exclusive).
