The EEPROMs on SFP modules are compatible both to I2C as well as SMBus. However, the kernel so far only supports I2C access. We add SMBus access routines, because the I2C driver for the RTL9300 HW only supports that protocol. At the same time we disable I2C access to PHYs on SFP modules as otherwise detection of any SFP module would fail. This is not in any way problematic at this point in time since the RTL93XX platform so far does not support PHYs on SFP modules. The patches are copied and rebased version of: https://bootlin.com/blog/sfp-modules-on-a-board-running-linux/ Signed-off-by: Daniel Golle <daniel@makrotopia.org> Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
