drm: bridge: dw-hdmi: Report connector status using callback

2019-10-29T12:30:22+00:00

Allow codec driver register callback function for plug event. The callback registration flow: dw-hdmi <--- hw-hdmi-i2s-audio <--- hdmi-codec dw-hdmi-i2s-audio implements hook_plugged_cb op so codec driver can register the callback. dw-hdmi exports a function dw_hdmi_set_plugged_cb so platform device can register the callback. When connector plug/unplug event happens, report this event using the callback. Make sure that audio and drm are using the single source of truth for connector status.

drm/bridge: dw-hdmi: Restore audio when setting a mode

2019-10-15T07:48:52+00:00

When setting a new display mode, dw_hdmi_setup() calls dw_hdmi_enable_video_path(), which disables all hdmi clocks, including the audio clock. We should only (re-)enable the audio clock if audio was already enabled when setting the new mode. Without this patch, on RK3288, there will be HDMI audio on some monitors if i2s was played to headphone when the monitor was plugged. ACER H277HU and ASUS PB278 are two of the monitors showing this issue.

drm/bridge: dw-hdmi: Add Dynamic Range and Mastering InfoFrame support

2019-10-10T10:50:00+00:00

Add support for configuring Dynamic Range and Mastering InfoFrame from the hdr_output_metadata connector property. This patch adds a use_drm_infoframe flag to dw_hdmi_plat_data that platform drivers use to signal when Dynamic Range and Mastering infoframes is supported. This flag is needed because Amlogic GXBB and GXL report same DW-HDMI version, and only GXL support DRM InfoFrame. These changes were based on work done by Zheng Yang to support DRM InfoFrame on the Rockchip 4.4 BSP kernel at [1] and [2] [1] https://github.com/rockchip-linux/kernel/tree/develop-4.4 [2] https://github.com/rockchip-linux/kernel/commit/d1943fde81ff41d7cca87f4a42f03992e90bddd5 Cc: Zheng Yang Signed-off-by: Jonas Karlman Reviewed-by: Neil Armstrong Reviewed-by: Andrzej Hajda Signed-off-by: Neil Armstrong Link: https://patchwork.freedesktop.org/patch/msgid/HE1PR06MB4011D7B916CBF8B740ACC45FAC9B0@HE1PR06MB4011.eurprd06.prod.outlook.com

drm/bridge: dw-hdmi: Refuse DDC/CI transfers on the internal I2C controller

2019-10-07T12:27:48+00:00

The DDC/CI protocol involves sending a multi-byte request to the display via I2C, which is typically followed by a multi-byte response. The internal I2C controller only allows single byte reads/writes or reads of 8 sequential bytes, hence DDC/CI is not supported when the internal I2C controller is used. The I2C transfers complete without errors, however the data in the response is garbage. Abort transfers to/from slave address 0x37 (DDC) with -EOPNOTSUPP, to make it evident that the communication is failing.

cec: add cec_adapter to cec_notifier_cec_adap_unregister()

2019-10-07T10:47:43+00:00

It is possible for one HDMI connector to have multiple CEC adapters. The typical real-world scenario is that where one adapter is used when the device is in standby, and one that's better/smarter when the device is powered up. The cec-notifier changes were made with that in mind, but I missed that in order to support this you need to tell cec_notifier_cec_adap_unregister() which adapter you are unregistering from the notifier. Add this additional argument. It is currently unused, but once all drivers use this, the CEC core will be adapted for these use-cases.

drm: bridge/dw_hdmi: add audio sample channel status setting

2019-09-13T08:43:51+00:00

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.

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
