-* AMD 10GbE driver (amd-xgbe)
-
-Required properties:
-- compatible: Should be "amd,xgbe-seattle-v1a"
-- reg: Address and length of the register sets for the device
- - MAC registers
- - PCS registers
- - SerDes Rx/Tx registers
- - SerDes integration registers (1/2)
- - SerDes integration registers (2/2)
-- interrupts: Should contain the amd-xgbe interrupt(s). The first interrupt
- listed is required and is the general device interrupt. If the optional
- amd,per-channel-interrupt property is specified, then one additional
- interrupt for each DMA channel supported by the device should be specified.
- The last interrupt listed should be the PCS auto-negotiation interrupt.
-- clocks:
- - DMA clock for the amd-xgbe device (used for calculating the
- correct Rx interrupt watchdog timer value on a DMA channel
- for coalescing)
- - PTP clock for the amd-xgbe device
-- clock-names: Should be the names of the clocks
- - "dma_clk" for the DMA clock
- - "ptp_clk" for the PTP clock
-- phy-mode: See ethernet.txt file in the same directory
-
-Optional properties:
-- dma-coherent: Present if dma operations are coherent
-- amd,per-channel-interrupt: Indicates that Rx and Tx complete will generate
- a unique interrupt for each DMA channel - this requires an additional
- interrupt be configured for each DMA channel
-- amd,speed-set: Speed capabilities of the device
- 0 - 1GbE and 10GbE (default)
- 1 - 2.5GbE and 10GbE
-
-The MAC address will be determined using the optional properties defined in
-ethernet.txt.
-
-The following optional properties are represented by an array with each
-value corresponding to a particular speed. The first array value represents
-the setting for the 1GbE speed, the second value for the 2.5GbE speed and
-the third value for the 10GbE speed. All three values are required if the
-property is used.
-- amd,serdes-blwc: Baseline wandering correction enablement
- 0 - Off
- 1 - On
-- amd,serdes-cdr-rate: CDR rate speed selection
-- amd,serdes-pq-skew: PQ (data sampling) skew
-- amd,serdes-tx-amp: TX amplitude boost
-- amd,serdes-dfe-tap-config: DFE taps available to run
-- amd,serdes-dfe-tap-enable: DFE taps to enable
