ab716b74 - drm/display/hdmi: implement hotplug functions

Tue, 24 Dec 2024 01:47:58 +0000

drm/display/hdmi: implement hotplug functionsThe HDMI Connectors need to perform a variety of tasks when the HDMIconnector state changes. Such tasks include setting or invalidating CECaddress, notifying HDMI codec driver, updating scrambler data, etc.Implementing such tasks in a driver-specific callbacks is error prone.Start implementing the generic helper function (currently handling onlythe HDMI Codec framework) to be used by drivers utilizing HDMI Connectorframework.Reviewed-by: Maxime Ripard Tested-by: Dave Stevenson Link: https://patchwork.freedesktop.org/patch/msgid/20241224-drm-bridge-hdmi-connector-v10-6-dc89577cd438@linaro.orgSigned-off-by: Dmitry Baryshkov List of files: /linux-6.15/drivers/gpu/drm/display/Kconfig

Tue, 24 Dec 2024 01:47:56 +0000

drm/bridge: connector: add support for HDMI codec frameworkAdd necessary glue code to be able to use new HDMI codec framework fromthe DRM bridge drivers. The drm_bridge implements a limited set of thehdmi_codec_ops interface, with the functions accepting bothdrm_connector and drm_bridge instead of just a generic void pointer.This framework is integrated with the DRM HDMI Connector framework, butcan also be used for DisplayPort connectors.Reviewed-by: Maxime Ripard Tested-by: Dave Stevenson Link: https://patchwork.freedesktop.org/patch/msgid/20241224-drm-bridge-hdmi-connector-v10-4-dc89577cd438@linaro.orgSigned-off-by: Dmitry Baryshkov List of files: /linux-6.15/drivers/gpu/drm/display/Kconfig

2063ca42 - drm/display: Drop obsolete dependency on COMPILE_TEST

Tue, 15 Oct 2024 11:46:06 +0000

drm/display: Drop obsolete dependency on COMPILE_TESTSince commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), itis possible to test-build any driver which depends on OF on anyarchitecture by explicitly selecting OF. Therefore depending onCOMPILE_TEST as an alternative is no longer needed.To avoid reintroducing the randconfig bug originally fixed by commit876271118aa4 ("drm/display: Fix build error without CONFIG_OF"),DRM_MSM which selects DRM_DISPLAY_DP_HELPER must explicitly dependon OF. This is consistent with what all other DRM drivers are doing.Signed-off-by: Jean Delvare Reviewed-by: Javier Martinez Canillas Cc: David Airlie Cc: Daniel Vetter Acked-by: Douglas Anderson Acked-by: Dmitry Baryshkov Reviewed-by: Abhinav Kumar Link: https://patchwork.freedesktop.org/patch/msgid/20241015134606.5b87093e@endymion.delvareSigned-off-by: Dmitry Baryshkov List of files: /linux-6.15/drivers/gpu/drm/display/Kconfig
