title: Toshiba TC358746 Parallel to MIPI CSI2 Bridge
maintainers:
- Marco Felsch <kernel@pengutronix.de>
description: |-
The Toshiba TC358746 converts a parallel video stream into a MIPI CSI-2
stream. The direction can be either parallel-in -> csi-out or csi-in ->
parallel-out The chip is programmable through I2C and SPI but the SPI
interface is only supported in parallel-in -> csi-out mode.
Note that the current device tree bindings only support the
parallel-in -> csi-out path.
