2*4882a593Smuzhiyun------------------------------
3*4882a593Smuzhiyun
4*4882a593SmuzhiyunThis comphy controller can be found on Marvell Armada 38x. It provides a
5*4882a593Smuzhiyunnumber of shared PHYs used by various interfaces (network, sata, usb,
6*4882a593SmuzhiyunPCIe...).
7*4882a593Smuzhiyun
8*4882a593SmuzhiyunRequired properties:
9*4882a593Smuzhiyun
10*4882a593Smuzhiyun- compatible: should be "marvell,armada-380-comphy"
11*4882a593Smuzhiyun- reg: should contain the comphy register location and length.
12*4882a593Smuzhiyun- #address-cells: should be 1.
13*4882a593Smuzhiyun- #size-cells: should be 0.
14*4882a593Smuzhiyun
15*4882a593SmuzhiyunOptional properties:
16*4882a593Smuzhiyun
17*4882a593Smuzhiyun- reg-names: must be "comphy" as the first name, and "conf".
18*4882a593Smuzhiyun- reg: must contain the comphy register location and length as the first
19*4882a593Smuzhiyun    pair, followed by an optional configuration register address and
20*4882a593Smuzhiyun    length pair.
21*4882a593Smuzhiyun
22*4882a593SmuzhiyunA sub-node is required for each comphy lane provided by the comphy.
23*4882a593Smuzhiyun
24*4882a593SmuzhiyunRequired properties (child nodes):
25*4882a593Smuzhiyun
26*4882a593Smuzhiyun- reg: comphy lane number.
27*4882a593Smuzhiyun- #phy-cells : from the generic phy bindings, must be 1. Defines the
28*4882a593Smuzhiyun               input port to use for a given comphy lane.
29*4882a593Smuzhiyun
