3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun - compatible : should be one of the listed compatibles
5*4882a593Smuzhiyun	- "brcm,sr-usb-combo-phy" is combo PHY has two PHYs, one SS and one HS.
6*4882a593Smuzhiyun	- "brcm,sr-usb-hs-phy" is a single HS PHY.
7*4882a593Smuzhiyun - reg: offset and length of the PHY blocks registers
8*4882a593Smuzhiyun - #phy-cells:
9*4882a593Smuzhiyun   - Must be 1 for brcm,sr-usb-combo-phy as it expects one argument to indicate
10*4882a593Smuzhiyun     the PHY number of two PHYs. 0 for HS PHY and 1 for SS PHY.
11*4882a593Smuzhiyun   - Must be 0 for brcm,sr-usb-hs-phy.
