From: "Rob Herring (Arm)" <[email-masked]>
Date: Mon, 13 Oct 2025 16:30:49 -0500

Convert amd,xgbe-seattle-v1a binding to DT schema format. It's a
straight-forward conversion.

-* 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
