[U-Boot] [PATCH v6 1/7] drivers: net: cpsw: Add reading of DT phy-handle node

[Dan Murphy]

Add the ability to read the phy-handle node of the
cpsw slave.  Upon reading this handle the phy-id
can be stored based on the reg node in the DT.

The phy-handle also needs to be stored and passed
to the phy to access any phy data that is available.

[U-Boot] [PATCH v6 2/7] net: zynq_gem: Add the passing of the phy-handle node

[Dan Murphy]

Add the ability to pass the phy-handle node offset
to the phy driver.  This allows the phy driver
to access the DT subnode's data and parse accordingly.

[U-Boot] [PATCH v6 4/7] net: phy: ti: Allow the driver to be more configurable

[Dan Murphy]

Not all devices use the same internal delay or fifo depth.
Add the ability to set the internal delay for rx or tx and the
fifo depth via the devicetree.  If the value is not set in the
devicetree then set the delay to the default.

If devicetree is not used then use the default defines within the
driver.

How do you want me to rebase these patches on the SGMII work from Michal on the ti.c
or off of master?  The patch I submitted was based off of the SGMII patchset.

Need to know how you want to handle this as I see the SGMII code is not in the base line
yet.

I'm pulling in some of Michal's patches this release. Please reference
which patches this depends on (patchwork links).

If the patches you depend on are acceptable (no changes requested)
then definitely base your changes on them, but point them out to me.

Joe fixing these will break readability of the code.
I will document this in the next patch submission

[Dan Murphy]

Move the phy_interface_is_rgmii to the phy.h
file for all phy's to be able to use the API.

This now aligns with the Linux kernel based on

[Dan Murphy]

The code assumed that if the interface is not RGMII configured
then it must be SGMII configured.  This device has the ability
to support most of the MII interfaces.  Therefore add the
helper for SGMII and only configure the device if the interface is
configured for SGMII.

It would be great if the phy could be handled generically.
Unfortunately there is no uniform description so far, so having each
driver parse it is the best we can do for now.

I can only fix a few there will still be at least 2 LTL warnings on this file and fixing
it will break readability

I don't see how to fix this.

If you plan to have a patch that you feel can't be clean, please
comment after the patch log with the reasoning. I had enough failures
in the patches this release that I have not investigated each one on
my own.
