Future SoCs are going to have more than 255 device clocks in certain cases, and thus the API must be extended to support this. The support is done in backwards compatible extension, in which the new u32 clock identifier fields are only used if the existing u8 size clock identifier is set as 255. In all the other cases, the existing u8 clock identifier is used. As the size of the messages sent / received is not verified for existing devices / old firmware, increasing the size of the messages from the end is also fine. Due to this reason, depending on ABI version isn't necessary either. Acked-by: Santosh Shilimkar <ssantosh@kernel.org> Signed-off-by: Tero Kristo <t-kristo@ti.com> |

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.
