RK3066's VPU IP block is the predecessor from what RK3288 has.
The hardware differences are:
- supports decoding frame sizes up to 1920x1088 only
- doesn't have the 'G1_REG_SOFT_RESET' register
(requires another .reset callback for hantro_codec_ops,
since writing this register will result in non-working
IP block)
- has one ACLK/HCLK per vdpu/vepu
- ACLKs can be clocked up to 300 MHz only
- no MMU
(no changes required: CMA will be transparently used)
Add a new RK3066 variant which reflect this differences. This variant
can be used for RK3188 as well.

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.
