mainlining shenanigans
Add support of Cirrus cs42l51 audio codec on stm32mp157a-dk1 board. Configuration overview: - SAI2A is the CPU interface used for the codec audio playback - SAI2B is the CPU interface used for the codec audio record - SAI2A is configured as a clock provider for the audio codec - SAI2A&B are configured as slave of the audio codec - SAI2A&B share the same interface of the audio codec Note: In master mode, cs42l51 audio codec provides a bitclock at 64 x FS, regardless of data width. This means that slot width is always 32 bits. Set slot width to 32 bits and slot number to 2 in SAI2A&B endpoint nodes, to match this constraint. dai-tdm-slot-num and dai-tdm-slot-width properties are used here, assuming that i2s is a special case of tdm, where slot number is 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.
