*	net: phy: mdio-i2c: support I2C MDIO protocol for RollBall SFP modules	Marek Behún	2022-10-03	1	-1/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Some multigig SFPs from RollBall and Hilink do not expose functional MDIO access to the internal PHY of the SFP via I2C address 0x56 (although there seems to be read-only clause 22 access on this address). Instead these SFPs PHY can be accessed via I2C via the SFP Enhanced Digital Diagnostic Interface - I2C address 0x51. The SFP_PAGE has to be selected to 3 and the password must be filled with 0xff bytes for this PHY communication to work. This extends the mdio-i2c driver to support this protocol by adding a special parameter to mdio_i2c_alloc function via which this RollBall protocol can be selected.

*	net: sfp: create/destroy I2C mdiobus before PHY probe/after PHY release	Marek Behún	2022-10-03	1	-0/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Instead of configuring the I2C mdiobus when SFP driver is probed, create/destroy the mdiobus before the PHY is probed for/after it is released. This way we can tell the mdio-i2c code which protocol to use for each SFP transceiver. Move the code that determines MDIO I2C protocol from sfp_sm_probe_for_phy() to sfp_sm_mod_probe(), where most of the SFP ID parsing is done. Don't allocate I2C bus if no PHY is expected.

*	add missing includes and forward declarations to networking includes under ↵	Jakub Kicinski	2022-07-28	1	-0/+4
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	linux/ Similarly to a recent include/net/ cleanup, this patch adds missing includes to networking headers under include/linux. All these problems are currently masked by the existing users including the missing dependency before the broken header.

*	net: xgene: Move shared header file into include/linux	Andrew Lunn	2020-08-27	1	-0/+130
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	This header file is currently included into the ethernet driver via a relative path into the PHY subsystem. This is bad practice, and causes issues for the upcoming move of the MDIO driver. Move the header file into include/linux to clean this up. v2: Move header to include/linux/mdio Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

	In preparation for moving all MDIO drivers into drivers/net/mdio, move the mdio-i2c header file into include/linux/mdio so it can be used by both the MDIO driver and the SFP code which instantiates I2C MDIO busses. v2: Add include/linux/mdio Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
