Checked with: checkpatch.pl --max-line-length=80 Changes from v2: - added comment into the patch adding support for RollBall I2C MDIO protocol, saying that we expect the SFP_PAGE not to be changed by the SFP code, as requested by Russell. If, in the future, SFP code starts modifying SFP_PAGE, we will have to handle it in mdio-i2c somehow - destruction of I2C MDIO bus in patch 3/5 now depends on whether the MDIO bus is not NULL, instead of whether PHY exists, as suggested by Russell - changed waiting time for RollBall module to initialize from 30 seconds to 25 seconds. Testing shows that it is never longer than 21-22 seconds, so waiting 25 seconds instead of 30 is IMO safe enough - added Russell's Reviewed-by tags where relevant Changes from v1: - wrapped to 80 columns as per Russell's request - initialization of RollBall MDIO I2C protocol moved from sfp.c to mdio-i2c.c as per Russell's request - second patch removes the 802.3z check also from phylink_sfp_config as suggested by Russell - creation/destruction of mdiobus for SFP now occurs before probing for PHY/after releasing PHY (as suggested by Russell) - the last patch became a little simpler after the above was done Cc: Andrew Lunn Cc: Russell King Marek Behún (5): net: phy: mdio-i2c: support I2C MDIO protocol for RollBall SFP modules net: phylink: allow attaching phy for SFP modules on 802.3z mode net: sfp: create/destroy I2C mdiobus before PHY probe/after PHY release net: phy: marvell10g: change MACTYPE if underlying MAC does not support it net: sfp: add support for multigig RollBall transceivers drivers/net/mdio/mdio-i2c.c | 236 +++++++++++++++++++++++++++++++++- drivers/net/phy/marvell10g.c | 31 +++++ drivers/net/phy/phylink.c | 5 +- drivers/net/phy/sfp.c | 65 ++++++++-- include/linux/mdio/mdio-i2c.h | 8 +- 5 files changed, 325 insertions(+), 20 deletions(-) base-commit: 0064c5c1b3bf2a695c772c90e8dea38426a870ff
