drm/ast: Move SIL164-based connector code into separate helpers

2022-02-08T12:40:18+00:00

Add helpers for initializing SIL164-based connectors. These used to be handled by the VGA connector code. But SIL164 provides output via DVI-I, so set the encoder and connector types accordingly. If a SIL164 chip has been detected, ast will now create a DVI-I connector instead of a VGA connector.

drm/ast: Move DP501-based connector code into separate helpers

2022-02-08T12:40:18+00:00

Add helpers for DP501-based connectors. DP501 provides output via DisplayPort. This used to be handled by the VGA connector code. If a DP501 chip has been detected, ast will now create a DisplayPort connector instead of a VGA connector. Remove the DP501 code from ast_vga_connector_helper_get_modes(). Also remove the call to drm_connector_update_edid_property(), which is performed by drm_get_edid().
