Linux kernel source tree

R-Car Sound is using almost same register mapping on each generation, therefore we can share it. Here indicates some memo/comments. SSI/SSIU/SCU have multi channels (SSI0 - SSI9 etc), but ADG is single, so, we don't need to have multi channel settings for it - rsnd_gen_regmap_init(..., 10, ..ADG, ...); + rsnd_gen_regmap_init(..., 1, ..ADG, ...); Gen4 added new SSI_BUSIF, but it is not used Gen4 calls rsnd_gen_regmap_init() for SDMC, but the address is calculated by rsnd_gen4_dma_addr(). It needs physical address, but other info are not needed. use NULL conf for it. - rsnd_gen_regmap_init(..., 10, ..SDMC, conf_sdmc); + rsnd_gen_regmap_init(..., 1, ..SDMC, conf_null); Gen4 have only SSI0/SSIU0, we don't need to have multi channel settings. - rsnd_gen_regmap_init(..., 10, ..SSI, ...); + rsnd_gen_regmap_init(..., 1, ..SSI, ...); SSI_MODE2 address is different between Gen2/3 and Gen4, but it is not used on Gen4. Thus we can share same regmap table.

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.
