Yanteng Si 79afc70002 net: stmmac: dwmac-loongson: Detach GMAC-specific platform data init
Loongson delivers two types of the network devices: Loongson GMAC and
Loongson GNET in the framework of four SOC/Chipsets revisions:

   Chip             Network  PCI Dev ID   Synopys Version   DMA-channel
LS2K1000 SOC         GMAC      0x7a03       v3.50a/v3.73a        1
LS7A1000 Chipset     GMAC      0x7a03       v3.50a/v3.73a        1
LS2K2000 SOC         GMAC      0x7a03          v3.73a            8
LS2K2000 SOC         GNET      0x7a13          v3.73a            8
LS7A2000 Chipset     GNET      0x7a13          v3.73a            1

The driver currently supports the chips with the Loongson GMAC network
device synthesized with a single DMA-channel available. As a
preparation before adding the Loongson GNET support detach the
Loongson GMAC-specific platform data initializations to the
loongson_gmac_data() method and preserve the common settings in the
loongson_default_data().

While at it drop the return value statement from the
loongson_default_data() method as redundant.

Note there is no intermediate vendor-specific PCS in between the MAC
and PHY on Loongson GMAC and GNET. So the plat->mac_interface field
can be freely initialized with the PHY_INTERFACE_MODE_NA value.

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.
