The current driver use HDMI hardware's auto CTS mode. We found that at high sample rates, the auto-calculated CTS value is incorrect, leading to silent outputs on devices that rely on n/cts to recover the sample rate, such as TV. Auto CTS mode was introduced in commitfdbdcc83ff("drm/bridge: dw-hdmi: Use automatic CTS generation mode when using non-AHB audio") to handle cases where audio clock and TMDS clock are not sourced from the same PLL. However, on RK platforms where both clocks are derived from the same PLL. This patch adds a "cts-manual" property to allow manual CTS configuration when clocks are co-sourced.

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.
