net: phy: broadcom: add support for BCM54811 PHY

2020-05-15T17:56:31+00:00

The BCM54811 PHY shares many similarities with the already supported BCM54810 PHY but additionally requires some semi-unique configuration. Signed-off-by: Kevin Lo Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: broadcom: Wire suspend/resume for BCM54810

2020-02-20T00:36:48+00:00

The BCM54810 PHY can use the standard BMCR Power down suspend, but needs a custom resume routine which first clear the Power down bit, and then re-initializes the PHY. While in low-power mode, the PHY only accepts writes to the BMCR register. The datasheet clearly says it: Reads or writes to any MII register other than MII Control register (address 00h) while the device is in the standby power-down mode may cause unpredictable results.

net: phy: broadcom: Have bcm54xx_adjust_rxrefclk() check for flags

2020-02-20T00:36:48+00:00

bcm54xx_adjust_rxrefclk() already checks for PHY_BRCM_AUTO_PWRDWN_ENABLE and PHY_BRCM_DIS_TXCRXC_NOENRGY in order to set the appropriate bit. The situation is a bit more complicated with the flag PHY_BRCM_RX_REFCLK_UNUSED but essentially amounts to the same situation. The default setting for the 125MHz clock is to be on for all PHYs and we still treat BCM50610 and BCM50610M specifically with the polarity of the bit reversed.

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

2019-10-24T03:42:52+00:00

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.
