Dylan Hung	9dbe33cf37	mdio: aspeed: Fix "Link is Down" issue ... The issue happened randomly in runtime. The message "Link is Down" is popped but soon it recovered to "Link is Up". The "Link is Down" results from the incorrect read data for reading the PHY register via MDIO bus. The correct sequence for reading the data shall be: 1. fire the command 2. wait for command done (this step was missing) 3. wait for data idle 4. read data from data register Cc: stable@vger.kernel.org Fixes: f160e99462 ("net: phy: Add mdio-aspeed") Reviewed-by: Joel Stanley <joel@jms.id.au> Signed-off-by: Dylan Hung <dylan_hung@aspeedtech.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Link: https://lore.kernel.org/r/20211125024432.15809-1-dylan_hung@aspeedtech.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>	2021-11-25 07:44:42 -08:00
Andrew Lunn	a9770eac51	net: mdio: Move MDIO drivers into a new subdirectory ... Move all the MDIO drivers and multiplexers into drivers/net/mdio. The mdio core is however left in the phy directory, due to mutual dependencies between the MDIO core and the PHY core. Take this opportunity to sort the Kconfig based on the menuconfig strings, and move the multiplexers to the end with a separating comment. v2: Fix typo in commit message Acked-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
