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. | |
15 | ||
16 | Example: | |
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>; | |
