gpu/drm: Ingenic: Fix opaque pointer casted to wrong type

2020-06-03T06:23:16+00:00

[ Upstream commit abf56fadf0e208abfb13ad1ac0094416058da0ad ] The opaque pointer passed to the IRQ handler is a pointer to the drm_device, not a pointer to our ingenic_drm structure. It still worked, because our ingenic_drm structure contains the drm_device as its first field, so the pointer received had the same value, but this was not semantically correct.

gpu/drm: ingenic: Fix bogus crtc_atomic_check callback

[ Upstream commit a53bcc19876498bdd3b4ef796c787295dcc498b4 ] The code was comparing the SoC's maximum height with the mode's width, and vice-versa. D'oh.

gpu/drm: ingenic: Add support for the JZ4770

2019-12-14T18:26:55+00:00

The LCD controller in the JZ4770 supports up to 720p. While there has been many new features added since the old JZ4740, which are not yet handled here, this driver still works fine. v2: No change Signed-off-by: Paul Cercueil Link: https://patchwork.freedesktop.org/patch/msgid/20191210144142.33143-6-paul@crapouillou.net # *** extracted tags *** Acked-by: Sam Ravnborg

gpu/drm: ingenic: Check for display size in CRTC atomic check

2019-12-14T18:26:39+00:00

Check that the requested display size isn't above the limits supported by the CRTC. - JZ4750 and older support up to 800x600; - JZ4755 supports up to 1024x576; - JZ4760 and JZ4770 support up to 720p; - JZ4780 supports up to 2k. v2: No change Signed-off-by: Paul Cercueil Link: https://patchwork.freedesktop.org/patch/msgid/20191210144142.33143-5-paul@crapouillou.net # *** extracted tags *** Acked-by: Sam Ravnborg

2019-12-14T18:26:25+00:00

While the LCD controller can effectively only support a maximum resolution of 800x600, the framebuffer's height can be much higher, since we can change the Y start offset. v2: No change Signed-off-by: Paul Cercueil Link: https://patchwork.freedesktop.org/patch/msgid/20191210144142.33143-4-paul@crapouillou.net # *** extracted tags *** Acked-by: Sam Ravnborg

drm/bridge: panel: Infer connector type from panel by default

2019-09-08T17:04:23+00:00

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 Reviewed-by: Boris Brezillon Signed-off-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20190904132804.29680-3-laurent.pinchart@ideasonboard.com

drm/ingenic: Hardcode panel type to DPI

The ingenic driver supports DPI panels only at the moment, so hardcode their type to DPI instead of Unknown.
