FSD CSI(Camera Serial Interface) IP bundles Link controller and DMA controller for receiving frames. FSD SoC has 12 instances of CSI IP and 3 D-PHY. 4 instances of CSI IP use 1 D-PHY. This patch series does the following: 1) Refactor the imx-mipi-csis driver to support platform specific clock names and interrupt handlers through device specific data (struct mipi_csis_info). 2) Add FSD CSI link controller support in imx-mipi-csis driver. 3) Introduce a new media driver for FSD CSI DMA providing support for video capture and streaming. These patches were tested on the FSD platform using the capture_raw_frames application. Changes since v1: 1. Addressed review comments from Laurent Pinchart to integrate the with imx-mipi-csis.c to handle the CSIS and expose it as a subdev.
