The BCM54616S PHY cannot work properly in RGMII->1000Base-X mode, mainly
because genphy functions are designed for copper links, and 1000Base-X
(clause 37) auto negotiation needs to be handled differently.
This patch enables 1000Base-X support for BCM54616S by customizing 3
driver callbacks, and it's verified to be working on Facebook CMM BMC
platform (RGMII->1000Base-KX):
- probe: probe callback detects PHY's operation mode based on
INTERF_SEL[1:0] pins and 1000X/100FX selection bit in SerDES 100-FX
Control register.
- config_aneg: calls genphy_c37_config_aneg when the PHY is running in
1000Base-X mode; otherwise, genphy_config_aneg will be called.
- read_status: calls genphy_c37_read_status when the PHY is running in
1000Base-X mode; otherwise, genphy_read_status will be called.
Note: BCM54616S PHY can also be configured in RGMII->100Base-FX mode, and
100Base-FX support is not available as of now.
