1 * AMD 10GbE driver (amd-xgbe)
4 - compatible: Should be "amd,xgbe-seattle-v1a"
5 - reg: Address and length of the register sets for the device
8 - SerDes Rx/Tx registers
9 - SerDes integration registers (1/2)
10 - SerDes integration registers (2/2)
11 - interrupt-parent: Should be the phandle for the interrupt controller
12 that services interrupts for this device
13 - interrupts: Should contain the amd-xgbe interrupt(s). The first interrupt
14 listed is required and is the general device interrupt. If the optional
15 amd,per-channel-interrupt property is specified, then one additional
16 interrupt for each DMA channel supported by the device should be specified.
17 The last interrupt listed should be the PCS auto-negotiation interrupt.
19 - DMA clock for the amd-xgbe device (used for calculating the
20 correct Rx interrupt watchdog timer value on a DMA channel
22 - PTP clock for the amd-xgbe device
23 - clock-names: Should be the names of the clocks
24 - "dma_clk" for the DMA clock
25 - "ptp_clk" for the PTP clock
26 - phy-mode: See ethernet.txt file in the same directory
29 - mac-address: mac address to be assigned to the device. Can be overridden
31 - dma-coherent: Present if dma operations are coherent
32 - amd,per-channel-interrupt: Indicates that Rx and Tx complete will generate
33 a unique interrupt for each DMA channel - this requires an additional
34 interrupt be configured for each DMA channel
35 - amd,speed-set: Speed capabilities of the device
36 0 - 1GbE and 10GbE (default)
39 The following optional properties are represented by an array with each
40 value corresponding to a particular speed. The first array value represents
41 the setting for the 1GbE speed, the second value for the 2.5GbE speed and
42 the third value for the 10GbE speed. All three values are required if the
44 - amd,serdes-blwc: Baseline wandering correction enablement
47 - amd,serdes-cdr-rate: CDR rate speed selection
48 - amd,serdes-pq-skew: PQ (data sampling) skew
49 - amd,serdes-tx-amp: TX amplitude boost
50 - amd,serdes-dfe-tap-config: DFE taps available to run
51 - amd,serdes-dfe-tap-enable: DFE taps to enable
