drm/bridge-connector: move to DRM_DISPLAY_HELPER module

2024-09-03T08:18:31+00:00

drm_bridge_connector is a "leaf" driver, belonging to the display helper, rather than the "CRTC" drm_kms_helper module. Move the driver to the drm/display and add necessary Kconfig selection clauses.

Revert "drm: Switch DRM_DISPLAY_HELPER to depends on"

2024-05-02T15:58:23+00:00

This reverts commit e075e496f516bf92bc0cbaf94d64e8d4a6b58321, as helper code should always be selected by the driver that needs it, for the convenience of the final user configuring a kernel. The user who configures a kernel should not need to know which helpers are needed for the driver he is interested in. Making a driver depend on helper code means that the user needs to know which helpers to enable first, which is very user-unfriendly.

drm/bridge: add lvds controller support for sam9x7

2024-04-23T07:29:43+00:00

Add a new LVDS controller driver for sam9x7 which does the following: - Prepares and enables the LVDS Peripheral clock - Defines its connector type as DRM_MODE_CONNECTOR_LVDS and adds itself to the global bridge list. - Identifies its output endpoint as panel and adds it to the encoder display pipeline - Enables the LVDS serializer Signed-off-by: Manikandan Muralidharan Signed-off-by: Dharma Balasubiramani Acked-by: Hari Prasath Gujulan Elango Reviewed-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/20240421011050.43265-3-dharma.b@microchip.com Signed-off-by: Neil Armstrong Link: https://patchwork.freedesktop.org/patch/msgid/20240421011050.43265-3-dharma.b@microchip.com

drm/bridge: it6505: Remove useless select

The IT6505 bridge Kconfig symbol selects a Kconfig symbol that doesn't exist. Remove it. Reviewed-by: Jani Nikula Link: https://lore.kernel.org/r/20240327-kms-kconfig-helpers-v3-13-eafee11b84b3@kernel.org Signed-off-by: Maxime Ripard

drm: Switch DRM_DISPLAY_HDCP_HELPER to depends on

2024-03-28T10:26:51+00:00

Most of our helpers have relied on being selected so far through Kconfig, but that creates issues when we have multiple layers of helpers with some depending on others. Indeed, select doesn't select a dependency's dependencies, and thus isn't super intuitive. Depends on however doesn't have that limitation, so we can just switch all the drivers that were selecting DRM_DISPLAY_HDCP_HELPER to depend on it.
