2021-01-18drm: Set vm_ops to GEM object's values during mmapThomas Zimmermann
The GEM mmap code relies on the GEM object's mmap callback to set the VMA's vm_ops field. This is easily forgotten and already led to a memory leak in the CMA helpers. Instead set the vm_ops field in the DRM core code to the GEM object's value. Drivers with different needs can override this in their mmap callback. v2: * support (vm_ops == NULL) if mmap is given; required by VRAM helpers Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Fixes: f5ca8eb6f9bd ("drm/cma-helper: Implement mmap as GEM CMA object functions") Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reported-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com> Tested-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Eric Anholt <eric@anholt.net> Cc: dri-devel@lists.freedesktop.org Link: https://patchwork.freedesktop.org/patch/msgid/20210115093038.10345-1-tzimmermann@suse.de

2021-01-14drm/sun4i: tcon: fix inverted DCLK polarityGiulio Benetti
During commit 88bc4178568b ("drm: Use new DRM_BUS_FLAG_*_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags") DRM_BUS_FLAG_* macros have been changed to avoid ambiguity but just because of this ambiguity previous DRM_BUS_FLAG_PIXDATA_(POS/NEG)EDGE were used meaning _SAMPLE_ not _DRIVE_. This leads to DLCK inversion and need to fix but instead of swapping phase values, let's adopt an easier approach Maxime suggested: It turned out that bit 26 of SUN4I_TCON0_IO_POL_REG is dedicated to invert DCLK polarity and this makes things really easier than before. So let's handle DCLK polarity by adding SUN4I_TCON0_IO_POL_DCLK_DRIVE_NEGEDGE as bit 26 and activating according to bus_flags the same way it is done for all the other signals polarity.

2021-01-12drm/fourcc: fix Amlogic format modifier masksSimon Ser
The comment says the layout and options use 8 bits, and the shift uses 8 bits. However the mask is 0xf, ie. 0b00001111 (4 bits). This could be surprising when introducing new layouts or options that take more than 4 bits, as this would silently drop the high bits. Make the masks consistent with the comment and the shift.

2021-01-12drm: distinguish return value of drm_dp_check_and_send_link_addressXiaogang Chen
drm_dp_check_and_send_link_address discovers MST device topology. It can return both positive and negative values. When it returns positive values there is no error found. If it returns negative values there is error found, such as get NAK , timeout, etc. Following drm_kms_helper_hotplug_event should be called when drm_dp_check_and_send_link_address returns positive value.

2021-01-12dt-bindings: display: Augment s6e63m0 bindingsLinus Walleij
This fixes the following problems with the s6e63m0 display bindings: - When used on the DSI bus, the panel is listed directly as a subnode on the DSI host so the "port" node is not compulsory. Remove "port" from required properties. - The panel contains its own backlight control, so reference the backlight common properties and list default-brightness and max-brightness as supported but optional properties.

2021-01-11dt-bindings: display: Use OF graph schemaRob Herring
Now that we have a graph schema, rework the display related schemas to use it. Mostly this is adding a reference to graph.yaml and dropping duplicate parts from schemas. In panel-common.yaml, 'ports' is dropped. Any binding using 'ports' should be one with more than 1 port node, and the binding must define what each port is. Note that ti,sn65dsi86.yaml, ti,tfp410,yaml and toshiba,tc358768.yaml will need further updates to use video-interfaces.yaml once that lands.

2021-01-14drm/amdgpu: Resize BAR0 to the maximum available size, even if it doesn't ↵Nirmoy Das
cover VRAM This allows BAR0 resizing to be done for cards which don't advertise support for a size large enough to cover the VRAM but which do advertise at least one size larger than the default. For example, my RX 5600 XT, which advertises 256MB, 512MB and 1GB.
