From e67f6037ae1be34b2b686bab72caa41d57714534 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Wed, 20 Oct 2021 14:39:44 +0200 Subject: drm/meson: split out encoder from meson_dw_hdmi This moves all the non-DW-HDMI code where it should be: an encoder in the drm/meson core driver. The bridge functions are copied as-is, except: - the encoder init uses the simple kms helper - the mode_set has been moved to atomic_enable() - debug prints are converted to dev_debg() For now the bridge attach flags is 0, DRM_BRIDGE_ATTACH_NO_CONNECTOR will be handled later. The meson dw-hdmi glue is slightly fixed to live without the encoder in the same driver.

The necessary connector properties are added to handle the same functionalities as the embedded dw-hdmi connector, i.e. the HDR metadata, the CEC notifier & other flags. The dw-hdmi output_port is set to 1 in order to look for a connector next bridge in order to get DRM_BRIDGE_ATTACH_NO_CONNECTOR working.
