Add support for the two GEM instances inside Mobileye EyeQ5 SoCs, using compatible "mobileye,eyeq5-gem". With it, add a custom init sequence that must grab a generic PHY and initialise it. We use bp->phy in both RGMII and SGMII cases. Tell our mode by adding a phy_set_mode_ext() during macb_open(), before phy_power_on(). We are the first users of bp->phy that use it in non-SGMII cases. The phy_set_mode_ext() call is made unconditionally. It cannot cause issues on platforms where !bp->phy or !bp->phy->ops->set_mode as, in those cases, the call is a no-op (returning zero). From reading upstream DTS, we can figure out that no platform has a bp->phy and a PHY driver that has a .set_mode() implementation: - cdns,zynqmp-gem: no DTS upstream. - microchip,mpfs-macb: microchip/mpfs.dtsi, &mac0..1, no PHY attached. - xlnx,versal-gem: xilinx/versal-net.dtsi, &gem0..1, no PHY attached. - xlnx,zynqmp-gem: xilinx/zynqmp.dtsi, &gem0..3, PHY attached to drivers/phy/xilinx/phy-zynqmp.c which has no .set_mode().

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.
