[PATCH 4.20 023/111] net: phy: Add missing features to PHY drivers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andrew Lunn <andrew@xxxxxxx>

[ Upstream commit 9e857a40dc4eba15a739b4194d7db873d82c28a0 ]

The bcm87xx and micrel driver has PHYs which are missing the .features
value. Add them. The bcm87xx is a 10G FEC only PHY. Add the needed
features definition of this PHY.

Fixes: 719655a14971 ("net: phy: Replace phy driver features u32 with link_mode bitmap")
