2021-02-04	net: dsa: xrs700x: Correctly address device over I2C	Tobias Waldekranz
	On read, master should send 31 MSB of the register (only even values are ever used), followed by a 1 to indicate read. Then, reading two bytes, the device will output the register's value. On write, master sends 31 MSB of the register, followed by a 0 to indicate write, followed by two bytes containing the register value. Flexibilis' documentation (version 1.3) specifies the opposite polarity (#read/write), but the scope indicates that it is, in fact, read/#write.

2021-01-15	net: dsa: add Arrow SpeedChips XRS700x driver	George McCollister
	Add a driver with initial support for the Arrow SpeedChips XRS7000 series of gigabit Ethernet switch chips which are typically used in critical networking applications. The switches have up to three RGMII ports and one RMII port. Management to the switches can be performed over i2c or mdio. Support for advanced features such as PTP and HSR/PRP (IEC 62439-3 Clause 5 & 4) is not included in this patch and may be added at a later date.
