drm: mxsfb: check framebuffer pitch

2020-10-29T09:11:21Z

[ Upstream commit d5a0c816900419105a12e7471bf074319dfa34be ] The lcdif IP does not support a framebuffer pitch (stride) other than framebuffer width. Check for equality and reject the framebuffer otherwise. This prevents a distorted picture when using 640x800 and running the Mesa graphics stack. Mesa tries to use a cache aligned stride, which leads at that particular resolution to width != stride. Currently Mesa has no fallback behavior, but rejecting this configuration allows userspace to handle the issue correctly.

drm/mxsfb: Make supported modifiers explicit

2020-07-20T08:47:37Z

In contrast to other display controllers on imx like DCSS and ipuv3 lcdif/mxsfb does not support detiling e.g. vivante tiled layouts. Since mesa might assume otherwise make it explicit that only DRM_FORMAT_MOD_LINEAR is supported.

drm/mxsfb: Use GEM CMA object functions

2020-06-10T07:04:45Z

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 Reviewed-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20200605073247.4057-28-tzimmermann@suse.de

drm/panel: decouple connector from drm_panel

2019-12-09T21:57:26Z

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.

drm/mxsfb: Update mxsfb to support a bridge

2019-10-14T20:19:22Z

Currently, the MXSFB DRM driver only supports a panel. But, its output display signal can also be redirected to another encoder, like a DSI controller. In this case, that DSI controller may act like a drm_bridge. In order support this use-case too, this patch adds support for drm_bridge in mxsfb.
