This series aims to enable pipe writeback functionality on ADLP where it has been tested. The plan is to slowly accomodate all supported hardware after this functionality is tested on them. This series also brings change to drm core but not in a drastic way. We introduce a helper which lets drivers have their own preallocated conenctor keeping the connector in drm_writeback_conenctor blank. This lets driver have more control over their connector but still use the drm core queues for job creation and signalling. Some new helpers have been added to aid drivers so that derivation of drm_connector from drm_writeback_connector and vice versa becomes easy for drivers that will use this helper since it won't be as straight forward as wb_conn->connector anymore. Driver not using these API will not be affected in anyways. This series enables the triggered captured mode where we need to trigger a capture.
