2020-06-10drm/mxsfb: Set GEM CMA functions with DRM_GEM_CMA_DRIVER_OPSThomas Zimmermann
DRM_GEM_CMA_DRIVER_OPS sets the functions in struct drm_driver to their defaults. No functional changes are made.

2020-06-10drm/mxsfb: 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. The implementation of vunmap is empty and left out in CMA's default object functions. v3: * convert to DRIVER_OPS macro in a separate patch Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200605073247.4057-28-tzimmermann@suse.de
2019-12-09drm/panel: decouple connector from drm_panelSam Ravnborg
To facilitate moving connector creation to display drivers, decouple the drm_connector from drm_panel. 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.

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.

2019-01-14drm/mxsfb: 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.

2018-09-26drm/mxsfb: Switch to drm_atomic_helper_commit_tail_rpmLeonard Crestez
The lcdif block is only powered on when display is active so plane updates when not enabled are not valid. Writing to an unpowered IP block is mostly ignored but can trigger bus errors on some chips. Prevent this situation by switching to drm_atomic_helper_commit_tail_rpm and having the drm core ensure atomic_plane_update is only called while the crtc is active. This avoids having to keep track of "enabled" bits inside the mxsfb driver. This also requires handling the vblank event for disable from mxsfb_pipe_disable.

According to the eLCDIF initialization steps listed in the MX6SX Reference Manual the eLCDIF block reset is mandatory. Without performing the eLCDIF reset the display shows garbage content when the kernel boots. In earlier tests this issue has not been observed because the bootloader was previously showing a splash screen and the bootloader display driver does properly implement the eLCDIF reset. Add the eLCDIF reset to the driver, so that it can operate correctly independently of the bootloader. Tested on a imx6sx-sdb board.

Currently the framebuffer content is displayed with incorrect offsets in both the vertical and horizontal directions. The fbdev version of the driver does not show this problem. Breno Lima dumped the eLCDIF controller registers on both the drm and fbdev drivers and noticed that the VDCTRL3 register is configured incorrectly in the drm driver. The fbdev driver calculates the vertical and horizontal wait counts of the VDCTRL3 register by doing: back porch + sync length. Looking at the horizontal and vertical timing diagram from include/drm/drm_modes.h this value corresponds to: crtc_[hv]total - crtc_[hv]sync_start So fix the VDCTRL3 register setting accordingly so that the eLCDIF controller can properly show the framebuffer content in the correct position.

2017-03-10drm: mxsfb: Fix crash when provided invalid DT bindingsMarek Vasut
The mxsfb driver will crash if the mxsfb DT node has a subnode, but the content of the subnode is not of-graph binding with an endpoint linking to panel. The crash was triggered by providing old-style panel bindings to the mxsfb driver instead of the new of-graph ones. The problem happens in mxsfb_create_output(), which is invoked from mxsfb_load(). The mxsfb_create_output() iterates over all mxsfb DT subnode endpoints and tries to bind a panel on each endpoint. If there is any problem binding the panel, that is, mxsfb->panel == NULL, this function will return an error code, otherwise success 0 is returned. If the subnodes do not specify of-graph binding with an endpoint, the iteration over endpoints in mxsfb_create_output() will have zero cycles and the function will immediatelly return 0, but the mxsfb->panel will remain NULL. This is propagated back into the mxsfb_load(), which does not detect any problem and expects that the mxsfb->panel is valid, thus calls mxsfb_panel_attach(). But since mxsfb->panel == NULL, mxsfb_panel_attach() is called with first argument NULL and this crashes the kernel. This patch fixes the problem by explicitly checking for valid mxsfb->panel at the end of the iteration in mxsfb_create_output().
