[PATCH v2 1/1] drm/bridge: ti-sn65dsi86: Use atomic variants of drm_bridge_funcs

Sam Ravnborg sam at ravnborg.org
Sun Jul 3 20:27:24 UTC 2022


Move away from the deprecated enable/disable operations in
drm_bridge_funcs and enable atomic use.

v3:
 - Drop use of DRM_BRIDGE_STATE_OPS

v2:
 - fix build (kernel test robot <lkp at intel.com>)
