Up to now the SPI alias was used as an index into an array defined in
the SPI driver to determine the SPI FIFO depth. Drop the dependency on
the SPI alias and specify the SPI FIFO depth directly into the SPI node.
exynos3250.dtsi defines the following aliases:
spi0 = &spi_0;
spi1 = &spi_1;
spi-s3c64xx.c driver defines the following fifo_lvl_mask for the
"samsung,exynos4210-spi" compatible:
.fifo_lvl_mask = { 0x1ff, 0x7F, 0x7F },
Thus spi0 was considered having a 256 byte FIFO depth, and spi1 a 64
byte FIFO depth. Update device tree with these FIFO depths. No
functional change expected.

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 reStructuredText 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.
