Subject: net/phy/mdio-i2c: Move header file to include/linux/mdio
X-Git-Tag: baikal/aarch64/sdk5.9~37
X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=c6993cc012a606278b855ebc64bfebf318e4b195;p=kernel.git

net/phy/mdio-i2c: Move header file to include/linux/mdio

[ Upstream commit 879a00d2b32cf39e1673406598151de277a71cc8 ]

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
