Subject: [PATCH] arm64: dts: fsl: ls1028a: Add Felix switch port DT node
|
|
|
|
Add the switch device node, available on PF5, so that the
|
|
switch port sub-nodes (net devices) can be linked to
|
|
corresponding board specific phy nodes (external ports) or
|
|
have their link mode defined (internal ports).
|
|
The switch device features 6 ports, 4 with external links
|
|
and 2 internally facing to the ls1028a SoC and connected via
|
|
fixed links to 2 internal enetc ethernet contoller ports.
|
|
Add the corresponding enetc internal port device nodes,
|
|
mapped to PF2 and PF6 PCIe functions.
|
|
And don't forget to enable the 4MB BAR4 in the root complex
|
|
ECAM space, where the switch registers are mapped.
