Linux kernel source tree

Add a helper function snd_soc_tdm_params_to_bclk() to calculate the bclk from params info and the tdm sots configuration. When using a TDM frame of N slots of width W bits: bclk = sample_rate * N * W As a convenience to simplify calling code, if the slot count or slot width are 0 a value will be obtained from the params. This allows calling code to use this one function to handle cases of TDM where only one parameter is fixed, or I2S where the slot width is fixed (for example to set a 32-bit slot for 24-bit samples). Also as a convenience the slot count can optionally be rounded up to a multiple. This is mainly useful for I2S systems, since I2S has two phases of LRCLK the number of slots is always a multiple of 2.

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.
