825fc49497 media: mgb4: Fix double debugfs remove
Fixes an error where debugfs_remove_recursive() is called first on a parent
directory and then again on a child which causes a kernel panic.

ff924ca08e media: pci: mgb4: Refactor struct resources
The struct resource end field signifies the end address not the
relative offset from the start field i.e size == (end - start) + 1.

Amend the .end field to specify the end address not the relative size
from the offset as is currently given.

Fixes cocci check:

media: mgb4: Follow renaming of SPI "master" to "controller"
In commit 8caab75fd2 ("spi: Generalize SPI "master" to "controller"")
some functions and struct members were renamed. To not break all drivers
compatibility macros were provided.

To be able to remove these compatibility macros push the renaming into
this driver.

9ea7be95d3 media: mgb4: Added support for T200 card variant
T200 card variants use the XC7A200T FPGA instead of XC7A100T. The SPI FLASH
memory layout is different as the FPGA requires bigger FW images.

0ab13674a9 media: pci: mgb4: Added Digiteq Automotive MGB4 driver
Digiteq Automotive MGB4 is a modular frame grabber PCIe card for automotive
video interfaces. As for now, two modules - FPD-Link and GMSL - are
available and supported by the driver. The card has two inputs and two
outputs (FPD-Link only).

In addition to the video interfaces it also provides a trigger signal
interface and a MTD interface for FPGA firmware upload.
