They do not. Read on the Snapdragon model while the sensor streamed 3844x2640 at 30 fps over one C-PHY trio (linux-next with the PHY series): 0x0016/0x0017 = 0x06 0x81 (model 0x0681) 0x0111 = 0x03 (CSI_SIGNALING_MODE, as written) 0x0114 = 0x00 (CSI_LANE_MODE, as written) 0x1600 = 0xff, 0x1601 = 0x03, 0x1602 = 0x04, 0x1603 = 0x01 So 0x1602 reports D-PHY only even while the part is transmitting C-PHY, the same values as on the Intel model. The capability block cannot confirm the mode on this sensor either way, so I will leave it out of the evidence in the commit message and say why. Thanks for reading it on your side. George
