Subject: [PATCH v3 0/2] drm/mediatek: Don't support hdmi connector creation

commit f01195148967 ("drm/mediatek: mtk_dpi: Create connector for bridges")
broke the display support for elm device since mtk_dpi calls
drm_bridge_attach with the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR
while mtk_hdmi does not yet support this flag.

These three patches fix that by adding support for DRM_BRIDGE_ATTACH_NO_CONNECTOR
in mtk_hdmi bridge attachment.

changes since v2:
1. squash patch 3 with patch 2 to not break bisection
2. remove the funtion mtk_hdmi_get_edid and inline its code in mtk_hdmi_bridge_get_edid
3. small aligment

changes since v1:
1. split the first patch - now the first patch only moves the bridge ops to the atomic API
while the replacement of the field 'conn' with the field '*curr_conn' is done in a new third patch.
2. in the function 'get_eld' use the current conn only if 'enabled = true'.

Dafna Hirschfeld (2):
  drm/mediatek: Switch the hdmi bridge ops to the atomic versions
  drm/mediatek: Don't support hdmi connector creation
