Renesas sound needs 8ch clock if TDM 6ch mode, and needs 2ch clock for 6ch or 8ch sound if Multi SSI mode. And these are related to before/after CTU (= Channel Transfer Unit). To calculate these we already has rsnd_runtime_channel_for_ssi() which returns runtime necessary channels. But, it based on runtime->channels which is not yet set when hw refine. We need to use hw_params instead of runtime->xxx when hw refine, and it is not needed after runtime was set. This patch adds new hw_params on rsnd_dai_stream, and it will be removed on rsnd_hw_params(). This is very temporary durty code, but it seems no choice at this point.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
