Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>: Current clock provider/consumer setting is set by dai_link->dai_fmt, and it is Codec base on Sound Card driver (= SND_SOC_DAIFMT_CBx_CFx). Current CPU/Codec drivers are already based on its own base (= SND_SOC_DAIFMT_Bx_Fx). So, Codec clock setting uses dai_link->dai_fmt as-is, and CPU side clock setting is created from Codec base setting by flipping. Because of this, we can't set both CPU/Codec clock consumer for example. To solve this issue, this patch-set adds new ext_fmt on each DAI. It can keep compatible with legacy style. 1. SND_SOC_DAIFMT_FORMAT_MASK 2. SND_SOC_DAIFMT_CLOCK 3. SND_SOC_DAIFMT_INV 4. SND_SOC_DAIFMT_CLOCK_PROVIDER dai_fmt : dai_link->dai_fmt = common settings ext_fmt : each DAI settings Legacy dai_fmt includes 1, 2, 3, 4 New style dai_fmt includes 1, 2, 3 ext_fmt includes 4 Audio-Graph-Card2 will use this new style by this patch-set. By this patch, Card2 default behavior (= no "clock-master / frame-master" settings on DT) will be changed, but no drivers are using it. In case of no DAI has "clock-master / frame-master" property on DT, it will be... Legacy CPU : provider (because flipped from Codec) Codec: consumer New style CPU : consumer Codec: consumer One note is that Simple-Card, Audio-Graph-Card don't implement this new style to keep compatiblily. In Overlay case, port order can be random, so we shouldn't use get_next() function to get next port.
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 reStructuredText 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.
