Unfortunately the frame format is not exactly identical between SPI and UART. In case of SPI there is an additional HW length at the beginning. So store the initial state to make the decoding state machine more flexible and easy to extend for UART support. Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> Signed-off-by: David S.

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.
