soc: mediatek: cmdq: Use mailbox rx_callback instead of cmdq_task_cb

2022-04-20T12:14:59Z

rx_callback is a standard mailbox callback mechanism and could cover the function of proprietary cmdq_task_cb, so use the standard one instead of the proprietary one. Client has changed to use the standard callback machanism and sync dma buffer in client driver, so remove the proprietary callback in cmdq helper.

soc: mediatek: cmdq: Remove cmdq_pkt_flush()

2021-01-31T11:35:46Z

rx_callback is a standard mailbox callback mechanism and could cover the function of proprietary cmdq_task_cb, so it is better to use the standard one instead of the proprietary one. But register rx_callback should before mbox_request_channel(), so remove cmdq_pkt_flush() and let client driver implement its own synchronous flush.

soc / drm: mediatek: cmdq: Remove timeout handler in helper function

2020-11-27T22:35:34Z

For each client driver, its timeout handler need to dump hardware register or its state machine information, and their way to detect timeout are also different, so remove timeout handler in helper function and let client driver implement its own timeout handler.
