	Hi all,

If an Ethernet PHY reset is asserted when the Ethernet driver is
initialized, the PHY cannot be probed:

    mdio_bus ee700000.ethernet-ffffffff: MDIO device at address 1 is missing

This happens because the Linux PHY subsystem tries to read the PHY
Identifier registers before handling PHY reset.  Hence if the PHY reset
was asserted before, identification fails.

An easy way to reproduce this issue is by using kexec to launch a new
kernel (the PHY reset will be asserted before starting the new kernel),
or by unbinding and rebinding the Ethernet driver (the PHY reset will be
asserted during unbind), e.g. on koelsch:

    echo ee700000.ethernet > /sys/bus/platform/drivers/sh-eth/unbind
    $ echo ee700000.ethernet > /sys/bus/platform/drivers/sh-eth/bind

The recommended approach[1][2] seems to be working around this issue by
adding compatible values to all ethernet-phy nodes, so Linux can
identify the PHY at any time, without reading the PHY ID from the
device, and regardless of the state of the PHY reset line.

Hence this patch series adds such compatible values to all Ethernet PHY
subnodes representing PHYs on all boards with Renesas ARM and ARM64
SoCs.  For easier review, I have split the series in one patch per PHY
model.

On most boards, I could verify the actual PHY ID at runtime[3], on other
boards I had to resort to schematics.

Kexec and Ethernet driver rebind have been tested on Koelsch and
Salvator-XS.

I plan to queue these in renesas-devel for v5.16.

Thanks for your comments!

Add compatible values to Ethernet PHY subnodes representing Micrel
KSZ8041 PHYs on RZ/G1 and R-Car Gen2 boards.  This allows software to
identify the PHY model at any time, regardless of the state of the PHY
reset line.

Add compatible values to Ethernet PHY subnodes representing Micrel
KSZ8041 PHYs on RZ/G1 and R-Car Gen2 boards.  This allows software to
identify the PHY model at any time, regardless of the state of the PHY
reset line.

Add compatible values to Ethernet PHY subnodes representing SMSC
LAN8710A PHYs on RZ/A1 and R-Mobile A1 boards.  This allows software to
identify the PHY model at any time, regardless of the state of the PHY
reset line.

I could not verify the PHY revision number (least significant nibble of
the ID) on gr-peach, due to lack of hardware.

* [PATCH 8/9] arm64: dts: renesas: Add compatible properties to KSZ9031 Ethernet PHYs

Add compatible values to Ethernet PHY subnodes representing Micrel
KSZ9031 PHYs on R-Car Gen3 boards.  This allows software to identify the
PHY model at any time, regardless of the state of the PHY reset line.

I could not verify the PHY revision number (least significant nibble of
the ID) on eagle, v3msk, conder, and v3hsk, due to lack of hardware.
