Stefan Agner 154105c0ba arm64: dts: meson: fix PHY deassert timing requirements
[ Upstream commit c183c406c4321002fe85b345b51bc1a3a04b6d33 ]

According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
registers. This fixes an issue seen on ODROID-C2 where the Ethernet
link doesn't come up when using ip link set down/up:
  [ 6630.714855] meson8b-dwmac c9410000.ethernet eth0: Link is Down
  [ 6630.785775] meson8b-dwmac c9410000.ethernet eth0: PHY [stmmac-0:00] driver [RTL8211F Gigabit Ethernet] (irq=36)
  [ 6630.893071] meson8b-dwmac c9410000.ethernet: Failed to reset the dma
  [ 6630.893800] meson8b-dwmac c9410000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed
  [ 6630.902835] meson8b-dwmac c9410000.ethernet eth0: stmmac_open: Hw setup failed

README

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.
