The number of CSI lanes that should be used is set to the CSI_CONTROL register by indirectly writing to the CSI_CONFW register. When the number of lanes is read back from the CSI_CONTROL register the value is usually correct, but we have seen that it suddenly is 1 for a short moment before the correct value is restored again. Toshiba have not figured out why that happen, but we have found it safer to store the value in the driver.

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.
