[PATCH v2 00/12] Add FSD CSI support

[Inbaraj E <inbaraj.e@samsung.com>]

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.

Here is the link to v1 patch for reference:
