broadcom-bcm87xx.txt (1020B)
1The Broadcom BCM87XX devices are a family of 10G Ethernet PHYs. They 2have these bindings in addition to the standard PHY bindings. 3 4Compatible: Should contain "broadcom,bcm8706" or "broadcom,bcm8727" and 5 "ethernet-phy-ieee802.3-c45" 6 7Optional 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. 15 16Example: 17 18 ethernet-phy@5 { 19 reg = <5>; 20 compatible = "broadcom,bcm8706", "ethernet-phy-ieee802.3-c45"; 21 interrupt-parent = <&gpio>; 22 interrupts = <12 8>; /* Pin 12, active low */ 23 /* 24 * Set PMD Digital Control Register for 25 * GPIO[1] Tx/Rx 26 * GPIO[0] R64 Sync Acquired 27 */ 28 broadcom,c45-reg-init = <1 0xc808 0xff8f 0x70>; 29 };
