Subject: [PATCH net-next v3 44/47] arm64: dts: ls1046a: Add serdes bindings
This adds bindings for the SerDes devices. They are disabled by default
to prevent any breakage on existing boards.
Signed-off-by: Sean Anderson <sean.anderson@...o.com>
---
Changes in v3:
- Describe modes in device tree
Changes in v2:
- Use one phy cell for SerDes1, since no lanes can be grouped
- Disable SerDes by default to prevent breaking boards inadvertently.
