2019-01-26lan743x: Provide Read/Write Access to on chip OTPBryan Whitehead1-5/+12
The LAN743x includes on chip One-Time-Programmable (OTP) memory. This patch extends the ethtool EEPROM read/write interface to access OTP memory space. The currently existing interface is limited, as it does not allow OTP read, and OTP writes are restricted to offset==0, length==512, and data[0]==0xF3. This patch removes these restrictions and adds a private flag called OTP_ACCESS, which is used to switch between EEPROM, and OTP modes. The private flag OTP_ACCESS is configurable through the ethtool --set-priv-flags command. And visible through the ethtool --show-priv-flags command. By default OTP_ACCESS is false, and there for previously existing EEPROM commands will work exactly the same. However now access to OTP requires one extra step of setting OTP_ACCESS to true. This flag controls the read, write, and length reporting, functions of ethtool. EEPROM presence is not checked when setting or clearing this flag. If the EEPROM is not present, the user, as before, will need to diagnose that using existing read and write function of ethtool, while OTP_ACCESS is false. Updates for V2: Added comments as to why this patch is needed. Added comments explaining that EEPROM presence is not check when setting or clearing the OTP_ACCESS flag. Added length checking to all otp/eeprom read/write functions. Signed-off-by: Bryan Whitehead <Bryan.Whitehead@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-11-27lan743x: Enable driver to work with LAN7431Bryan Whitehead1-0/+1
This driver was designed to work with both LAN7430 and LAN7431. The only difference between the two is the LAN7431 has support for external phy. This change adds LAN7431 to the list of recognized devices supported by this driver. Updates for v2: changed 'fixes' tag to match defined format fixes: 23f0703c125b ("lan743x: Add main source files for new lan743x driver") Signed-off-by: Bryan Whitehead <Bryan.Whitehead@microchip.com> Signed-off-by: David S.
