1 The Broadcom BCM87XX devices are a family of 10G Ethernet PHYs. They
2 have these bindings in addition to the standard PHY bindings.
3
4 Compatible: Should contain "broadcom,bcm8706" or "broadcom,bcm8727" and
5 "ethernet-phy-ieee802.3-c45"
6
7 Optional Properties:
8
9 - broadcom,c45-reg-init : one of more sets of 4 cells. The first cell
10 is the MDIO Manageable Device (MMD) address, the second a register
11 address within the MMD, the third cell contains a mask to be ANDed
12 with the existing register value, and the fourth cell is ORed with
13 he result to yield the new register value. If the third cell has a
14 value of zero, no read of the existing value is performed.
