Commit Message

Sean Anderson July 15, 2022, 9:59 p.m. UTC
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@seco.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.
