Subject: media: cadence: csi2rx: Fix stream data configuration Author: Pratyush Yadav <[email protected]> Date: Mon Oct 9 18:39:35 2023 +0530 Firstly, there is no VC_EN bit present in the STREAM_DATA_CFG register. Bit 31 is part of the VL_SELECT field. Remove it completely. Secondly, it makes little sense to enable ith virtual channel for ith stream. Sure, there might be a use-case that demands it. But there might also be a use case that demands all streams to use the 0th virtual channel. Prefer this case over the former because it is less arbitrary and also makes it very clear what the limitations of the current driver is instead of giving a false impression that multiple virtual channels are supported.
