commita11db8d8b4upstream. The Rockchip Video Decoder driver expects reg-names to be mandatory for RK3576 and RK3588 SoCs, however the binding does not currently require the use of them. As a consequence, driver would fail to probe with a hypothetical devicetree that doesn't provide the reg-names for these SoCs, but which is otherwise a perfectly valid DT from the binding perspective. Update the binding and make reg-names required for the aforementioned SoCs. While this change introduces an ABI break, the expected impact on potential users would be minimal, if any, since the old SoCs are unaffected, while the video decoder support for these newer variants in mainline driver and devicetrees hasn't been released yet. Moreover, this is also a prerequisite for a subsequent binding update introducing an alternative reg-names order, according to the address-based listing in the vendor's datasheet.

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.
