The MT8188 video decoder pipeline has two hardware IP blocks: LAT and Core, which are powered by vdec0 and vdec1 power domains, respectively. The hardware design includes a dependency between the vdec0 and vdec1 power domains to ensure that Core is powered down before LAT. Without correctly describing this dependency in DT, the system will fail to suspend. As a comparable reference, MT8192 also uses the LAT + Core decoding pipeline, and it has the correct power domain dependency defined in DT. Update vdec1 as a sub-domain of vdec0 in MT8188 DT to reflect the hardware design. Also, use more specific clock names for both power domains.

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 reStructuredText 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.
