====================
drivers: net: cpsw: phy-handle fixes
This series fixes a number of related issues around using phy-handle
properties in cpsw emac nodes.
Patch 1 fixes a bug if more than one slave is used, and either
slave uses the phy-handle property in the devicetree.
Patch 2 fixes a NULL pointer dereference which can occur if a
phy-handle property is used and of_phy_connect() return NULL,
such as with a bad devicetree.
Patch 3 fixes an issue where the phy-mode property would be ignored
if a phy-handle property was used. This also fixes a bogus error
message that would be emitted.
Patch 4 fixes makes the binding documentation more explicit that
exactly one PHY property should be used, and also marks phy_id as
deprecated.
Patch 5 cleans up the fixed-link case to work like the now-fixed
phy-handle case.
I have tested on the following hardware configurations:
- (EVMSK) dual emac, phy_id property in both slaves
- (EVMSK) dual emac, phy-handle property in both slaves
- (EVMSK) a bad phy-handle property pointing to &mmc1
- (EVMSK) phy_id property with incorrect PHY address
- (BeagleBoneBlack) single emac, phy_id property
- (custom) single emac, fixed-link subnode
Andrew Goodbody reported testing v2 on a board that doesn't use
dual_emac mode, but with 2 PHYs using phy-handle properties [1].
Nicolas Chauvet reported testing v2 on an HP t410 (dm8148).
Markus Brunner reported testing v1 on the following [2]:
- emac0 with phy_id and emac1 with fixed phy
- emac0 with phy-handle and emac1 with fixed phy
- emac0 with fixed phy and emac1 with fixed phy
