This series adds support the other two AIFs present in the sun8i codec,
which can be used for codec2codec DAI links.
This series first fills out the DAI driver, removing assumptions that
were made for AIF1 (16 bits, 2 channels, certain clock inversions). Some
new logic is required to handle 3 DAIs and the ADC/DAC sharing the same
clock. Finally, it adds the new DAIs, and hooks them up with DAPM
widgets and routes per the hardware topology.
To minimize the number of patches in this series, related device tree
patches (increasing #sound-dai-cells, adding new DAI links) will be sent
separately.
Changes from v1:
- Patches 1-8 from v1 (DAPM changes) were merged
- Prefixed AIF constants with "SUN8I_CODEC_" [1, 7, 10, 16, 17]
- Renamed variables in sun8i_codec_set_fmt for clarity [3]
- Update sysclk->sysclk_rate if later calls to hw_params change the
sample rate (thanks Chen-Yu for reminding me of this) [11]
- Select COMMON_CLK for clk_set_rate_exclusive [12]
- Add comments and hopefully clarify the clock protection logic [12]
- Make the error message more concise and put it on one line [12]
- Drop the "reg" variable holding SUN8I_AIF_CLK_CTRL(dai->id) [15]
- Rename "div_reg" to "clk_reg" and adjust comments for clarity [17]
- Improve the AIF2/AIF3 rate mismatch error message [17]
- Minor grammar/wording fixes in commit messages [2, 4, 7, 8, 16, 17]
- Added Maxime's Acked-by: [1-2, 4-9, 11, 13-14, 16]

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.
