The larb-id may be remapped in the smi-common, this means the
larb-id reported in the mtk_iommu_isr isn't the real larb-id,
Take mt8183 as a example:
M4U
|
---------------------------------------------
| SMI common |
-0-----7-----5-----6-----1-----2------3-----4- <- Id remapped
| | | | | | | |
larb0 larb1 IPU0 IPU1 larb4 larb5 larb6 CCU
disp vdec img cam venc img cam
As above, larb0 connects with the id 0 in smi-common.
larb1 connects with the id 7 in smi-common.
...
If the larb-id reported in the isr is 7, actually it's larb1(vdec).
In order to output the right larb-id in the isr, we add a larb-id
remapping relationship in this patch.
If there is no this larb-id remapping in some SoCs, use the linear
mapping array instead.
This also is a preparing patch for mt8183.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
