2019-09-16drm/connector: Allow max possible encoders to attach to a connectorJosé Roberto de Souza12-83/+55
Currently we restrict the number of encoders that can be linked to a connector to 3, increase it to match the maximum number of encoders that can be initialized(32). To more effiently do that lets switch from an array of encoder ids to bitmask. v2: Fixing missed return on amdgpu_dm_connector_to_encoder() Suggested-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: dri-devel@lists.freedesktop.org Cc: intel-gfx@lists.freedesktop.org Cc: nouveau@lists.freedesktop.org Cc: amd-gfx@lists.freedesktop.org Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190913232857.389834-2-jose.souza@intel.com

2019-09-13drm: bridge/dw_hdmi: add audio sample channel status settingYakir Yang4-0/+24
When transmitting IEC60985 linear PCM audio, we configure the Aduio Sample Channel Status information in the IEC60958 frame. The status bit is already available in iec.status of hdmi_codec_params. This fix the issue that audio does not come out on some monitors (e.g. LG 22CV241) Note that these registers are only for interfaces: I2S audio interface, General Purpose Audio (GPA), or AHB audio DMA (AHBAUDDMA). For S/PDIF interface this information comes from the stream. Currently this function dw_hdmi_set_channel_status is only called from dw-hdmi-i2s-audio in I2S setup.

Use the new cec_notifier_conn_(un)register() functions to (un)register the notifier for the HDMI connector, and fill in the cec_connector_info. Changes since v7: - err_runtime_disable -> err_rpm_disable Changes since v2: - removed unnecessary call to invalidate phys address before deregistering the notifier, - use cec_notifier_phys_addr_invalidate instead of setting invalid address on a notifier.

2019-09-09drm/stm: ltdc: add pinctrl for DPI encoder modeYannick Fertré1-0/+35
The implementation of functions encoder_enable and encoder_disable make possible to control the pinctrl according to the encoder type. The pinctrl must be activated only if the encoder type is DPI. This helps to move the DPI-related pinctrl configuration from all the panel or bridge to the LTDC dt node.

2019-09-08drm/bridge: panel: Infer connector type from panel by defaultLaurent Pinchart16-37/+93
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
2019-09-08drm/panel: Add and fill drm_panel type fieldLaurent Pinchart41-41/+112
Add a type field to the drm_panel structure to report the panel type, using DRM_MODE_CONNECTOR_* macros (the values that make sense are LVDS, eDP, DSI and DPI). This will be used to initialise the corresponding connector type. Update all panel drivers accordingly. The panel-simple driver only specifies the type for the known to be LVDS panels, while all other panels are left as unknown and will be converted on a case-by-case basis as they all need to be carefully reviewed.

2019-09-06drm: Use EOPNOTSUPP, not ENOTSUPPDaniel Vetter2-4/+4
- it's what we recommend in our docs: https://dri.freedesktop.org/docs/drm/gpu/drm-uapi.html#recommended-ioctl-return-values - it's the overwhelmingly used error code for "operation not supported", at least in drm core (slightly less so in drivers): $ git grep EOPNOTSUPP -- drivers/gpu/drm/*c | wc -l 83 $ git grep ENOTSUPP -- drivers/gpu/drm/*c | wc -l 5 - include/linux/errno.h makes it fairly clear that these are for nfsv3 (plus they also have error codes above 512, which is the block with some special behaviour ...) /* Defined for the NFSv3 protocol */ If the above isn't reflecting current practice, then I guess we should at least update the docs. Noralf commented: Ben Hutchings made this comment[1] in a thread about use of ENOTSUPP in drivers: glibc's strerror() returns these strings for ENOTSUPP and EOPNOTSUPP respectively: "Unknown error 524" "Operation not supported" So at least for errors returned to userspace EOPNOTSUPP makes sense. José asked: > Hopefully this will not break any userspace None of the functions in drm_edid.c affected by this reach userspace, it's all driver internal. Same for the mipi function, that error code should be handled by drivers. Drivers are supposed to remap "the hw is on fire" to EIO when reporting up to userspace, but I think if a driver sees this it would be a driver bug. v2: Augment commit message with comments from Noralf and José Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Acked-by: Noralf Trønnes <noralf@tronnes.org> Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Sean Paul <sean@poorly.run> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Andres Rodriguez <andresx7@gmail.com> Cc: Noralf Trønnes <noralf@tronnes.org> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190904143942.31756-1-daniel.vetter@ffwll.ch
