net: phy: broadcom: Set proper 1000BaseX/SGMII interface mode for BCM54616S

2021-03-30T12:32:05Z

[ Upstream commit 3afd0218992a8d1398e9791d6c2edd4c948ae7ee ] The default configuration for the BCM54616S PHY may not match the desired mode when using 1000BaseX or SGMII interface modes, such as when it is on an SFP module. Add code to explicitly set the correct mode using programming sequences provided by Bel-Fuse: https://www.belfuse.com/resources/datasheets/powersolutions/ds-bps-sfp-1gbt-05-series.pdf https://www.belfuse.com/resources/datasheets/powersolutions/ds-bps-sfp-1gbt-06-series.pdf Signed-off-by: Robert Hancock Acked-by: Florian Fainelli Signed-off-by: David S.

net: phy: broadcom: add cable test support

2020-05-13T19:52:38Z

Most modern broadcom PHYs support ECD (enhanced cable diagnostics). Add support for it in the bcm-phy-lib so they can easily be used in the PHY driver. There are two access methods for ECD: legacy by expansion registers and via the new RDB registers which are exclusive. Provide functions in two variants where the PHY driver can choose from. To keep things simple for now, we just switch the register access to expansion registers in the RDB variant for now. On the flipside, we have to keep a bus lock to prevent any other non-legacy access on the PHY. The results of the intra-pair tests are inconclusive (at least for the BCM54140). Most of the times half the length is reported but sometimes the length is correct. Signed-off-by: Michael Walle Reviewed-by: Florian Fainelli Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: add Broadcom BCM54140 support

2020-04-22T19:14:18Z

The Broadcom BCM54140 is a Quad SGMII/QSGMII Copper/Fiber Gigabit Ethernet transceiver. This also adds support for tunables to set and get downshift and energy detect auto power-down. The PHY has four ports and each port has its own PHY address. There are per-port registers as well as global registers. Unfortunately, the global registers can only be accessed by reading and writing from/to the PHY address of the first port. Further, there is no way to find out what port you actually are by just reading the per-port registers. We therefore, have to scan the bus on the PHY probe to determine the port and thus what address we need to access the global registers.

net: phy: broadcom: add 1000Base-X support for BCM54616S

2019-10-24T03:42:52Z

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.
