Allwinner has previously released a H616 audio driver which also provides sigma-delta modulation for the audio PLL clocks. This approach is used in other Allwinner SoCs, including the H3 and A64. The manual-provided clock values are: PLL_AUDIO(hs) = 24 MHz*N/M1 PLL_AUDIO(4X) = 24 MHz*N/M0/M1/P PLL_AUDIO(2X) = 24 MHz*N/M0/M1/P/2 PLL_AUDIO(1X) = 24 MHz*N/M0/M1/P/4 A fixed post-divider of 2 is used to account for a M0 divider of 2, which cannot be modelled by the existing macros and ccu_nm struct. Add SDM to the H616 clock control unit driver.

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.
