* drm_bridge_helper_reset_crtc - Reset the pipeline feeding a bridge
|
|
* @bridge: DRM bridge to reset
|
|
* @ctx: lock acquisition context
|
|
*
|
|
* Reset a @bridge pipeline. It will power-cycle all active components
|
|
* between the CRTC and connector that bridge is connected to.
|
|
*
|
|
* As it relies on drm_atomic_helper_reset_crtc(), the same limitations
|
|
* apply.
|
|
*
|
|
* Returns:
|
|
*
|
|
* 0 on success or a negative error code on failure. If the error
|
|
* returned is EDEADLK, the whole atomic sequence must be restarted.
