| 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>; |
