[Ray Jui]

Any comment on this DT change to enable PCIe PHY support for Cygnus?

Note the PHY driver has been accepted and is in v4.4.

Thanks,

Ray

This caused the DTC compiler to warn:

Warning (reg_format): "reg" property in /axi/phy@0301d0a0/phy@0 has
invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)
Warning (reg_format): "reg" property in /axi/phy@0301d0a0/phy@1 has
invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)

value for /axi/phy@0301d0a0/phy@0

I added an #address-cells = <0> and #size-cells = <1> to fix this, since
your reg property is a single digit.

Sorry I missed that. Both are required properties.

Did you mean #address-cells = <1> and #size-cells = <0>?
