[edk2] [PATCH edk2-platforms 7/8] Silicon/SynQuacer/DeviceTree: update NETSEC DT node to latest binding

[edk2] [PATCH edk2-platforms 7/8] Silicon/SynQuacer/DeviceTree: update NETSEC DT node to latest binding
Posted by Ard Biesheuvel 6 years, 9 months ago 
The upstream version of the Linux NETSEC driver expects the PHY DT
node to appear under a MDIO subnode, so fix this in the device tree.
Fix the node name as well, this should be 'ethernet' not 'netsec',
and add a clock-names property describing the single clock reference
as 'phy_ref_clk'.

Also, move the PHY subnode into the per-platform .dts file so we can
set the unit address in the node name. This is necessary because recent
versions of the DT compiler are more finicky about this.

Presumably the only kernels this may break are using non-upstream code?
If so:

Yes. The upstream version is not quite upstream yet - it is now
[finally] queued, for inclusion in v4.16
