Subject: [PATCH 2/3] [v2] powerpc: fsl: update fman dt binding for PCS PHY
From: Shaohui Xie <Shaohui.Xie@...escale.com>
PCS PHY can support backplane (1000BASE-KX and 10GBASE-KR), this needs
to change corresponding serdes lane settings, so a reference is needed
for serdes lane. This patch describes properties needed for PCS PHY to
support backplane.

PCS PHY addr must be '0'.

+ - phy-mode: string, operation mode of the PHY interface; must be "1000base-kx"
+ for 1000BASE-KX, or "10gbase-kr" for 10GBASE-KR.
+ - fsl-lane-handle: phandle, specifies a reference to a node representing a Serdes.
+ - fsl-lane-reg: offset and length of the register set for the serdes lane.
