1*4882a593SmuzhiyunThe Broadcom BCM87XX devices are a family of 10G Ethernet PHYs. They 2*4882a593Smuzhiyunhave these bindings in addition to the standard PHY bindings. 3*4882a593Smuzhiyun 4*4882a593SmuzhiyunCompatible: Should contain "broadcom,bcm8706" or "broadcom,bcm8727" and 5*4882a593Smuzhiyun "ethernet-phy-ieee802.3-c45" 6*4882a593Smuzhiyun 7*4882a593SmuzhiyunOptional Properties: 8*4882a593Smuzhiyun 9*4882a593Smuzhiyun- broadcom,c45-reg-init : one of more sets of 4 cells. The first cell 10*4882a593Smuzhiyun is the MDIO Manageable Device (MMD) address, the second a register 11*4882a593Smuzhiyun address within the MMD, the third cell contains a mask to be ANDed 12*4882a593Smuzhiyun with the existing register value, and the fourth cell is ORed with 13*4882a593Smuzhiyun he result to yield the new register value. If the third cell has a 14*4882a593Smuzhiyun value of zero, no read of the existing value is performed. 15*4882a593Smuzhiyun 16*4882a593SmuzhiyunExample: 17*4882a593Smuzhiyun 18*4882a593Smuzhiyun ethernet-phy@5 { 19*4882a593Smuzhiyun reg = <5>; 20*4882a593Smuzhiyun compatible = "broadcom,bcm8706", "ethernet-phy-ieee802.3-c45"; 21*4882a593Smuzhiyun interrupt-parent = <&gpio>; 22*4882a593Smuzhiyun interrupts = <12 8>; /* Pin 12, active low */ 23*4882a593Smuzhiyun /* 24*4882a593Smuzhiyun * Set PMD Digital Control Register for 25*4882a593Smuzhiyun * GPIO[1] Tx/Rx 26*4882a593Smuzhiyun * GPIO[0] R64 Sync Acquired 27*4882a593Smuzhiyun */ 28*4882a593Smuzhiyun broadcom,c45-reg-init = <1 0xc808 0xff8f 0x70>; 29*4882a593Smuzhiyun }; 30
