Subject: media: rcar-csi2: Add warning for PHY speed less than minimum Author: Suresh Udipi <[email protected]> Date: Fri Aug 13 17:07:55 2021 +0200 Add a warning message when the selected PHY speed is less than supported minimum PHY speed given in the hsfreq table[1]. For raspberry pi camera capture on Kingfisher board with resolution 640x480, the calculated PHY speed is 48 mbps which is less than the minimum PHY speed 80 Mbps from the table[1]. But in this cases capture is successful.
