Add SPI port configuration for Exynos850 SoC. It has 3 USI blocks which can be configured in SPI mode: * spi_0: BLK_PERI_SPI_0 (0x13940000) * spi_1: BLK_ALIVE_USI_CMGP00 (0x11d00000) * spi_2: BLK_ALIVE_USI_CMGP01 (0x11d20000) SPI FIFO depth is 64 bytes for all those SPI blocks, so the .fifo_lvl_mask value is set to 0x7f. All blocks have DIV_4 as the default internal clock divider, and an internal loopback mode to run a loopback test.

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.
