Drop the fifo_lvl_mask and rx_lvl_offset and switch to the new port config data. Advantages of the change: - drop dependency on the OF alias ID. - FIFO depth is inferred from the compatible. GS101 integrates 16 SPI IPs, all with 64 bytes FIFO depths. - use full mask for SPI_STATUS.{RX, TX}_FIFO_LVL fields. Using partial masks is misleading and can hide problems of the driver logic. S3C64XX_SPI_ST_TX_FIFO_RDY_V2 was defined based on the USI's SPI_VERSION.USI_IP_VERSION register field, which has value 2 at reset. MAX_SPI_PORTS is updated to reflect the maximum number of ports for the rest of the compatibles.

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.
