Changes in v4:
- Remove type $ref from binding
- Remove '|' from description in binding
- Change helper function from:
    static int phy_get_int_delay_property(struct device *dev, const char *name)
  to:
    static int phy_get_u32_property(struct device *dev, const char *name, u32 *val)
- Apply helper function to phy_get_internal_delay
- Link to v3: https://lore.kernel.org/r/20250204-dp83822-tx-swing-v3-0-9798e96500d9@xxxxxxxxxxxx

Changes in v3:
- Switch to tx-amplitude-100base-tx-percent in bindings
- Link to v2: https://lore.kernel.org/r/20250120-dp83822-tx-swing-v2-0-07c99dc42627@xxxxxxxxxxxx

Changes in v2:
- Remove binding ti,tx-amplitude-100base-tx-millivolt from ti,dp83822.yaml
- Add binding tx-amplitude-100base-tx-gain-milli to ethernet-phy.yaml
- Add helper to get tx amplitude gain from DT
- Link to v1: https://lore.kernel.org/r/20250113-dp83822-tx-swing-v1-0-7ed5a9d80010@xxxxxxxxxxxx
