PATCH 1 - Add MII-Lite PHY interface mode as defined by Broadcom for their two-wire PHYs. It can be used with most Ethernet controllers under certain limitations (no half-duplex link modes etc.). PATCH 2 - Add MII-Lite PHY interface type PATCH 3 - Activation of MII-Lite interface mode on Broadcom bcm5481x PHYs PATCH 4 - Fix the BCM54811 PHY initialization so that it conforms to the datasheet regarding a reserved bit in the LRE Control register, which must be written to zero after every device reset. Also fix the LRE Status register reading, there is another bit to be ignored on bcm54811. Changes in v2: - Applied reviewers' comments - Divided into more patches (separated common and Broadcom PHY specific code) Changes in v3: - Added MII-Lite documentation Changes in v4: - Added missing Fixes headers Changes in v5: - Removed unused PHY register bits definition Kamil Horák - 2N (4): net: phy: MII-Lite PHY interface mode dt-bindings: ethernet-phy: add MII-Lite phy interface type net: phy: bcm5481x: MII-Lite activation net: phy: bcm54811: Fix the PHY initialization .../bindings/net/ethernet-controller.yaml | 1 + Documentation/networking/phy.rst | 7 ++++ drivers/net/phy/broadcom.c | 39 ++++++++++++++++--- drivers/net/phy/phy-core.c | 1 + drivers/net/phy/phy_caps.c | 4 ++ drivers/net/phy/phylink.c | 1 + include/linux/brcmphy.h | 6 +++ include/linux/phy.h | 4 ++ 8 files changed, 58 insertions(+), 5 deletions(-) -- 2.39.5
