Subject: [PATCH] net: marvell: neta: disable comphy when setting mode
|
|
MIME-Version: 1.0

|
Content-Type: text/plain; charset=UTF-8

|
The comphy driver for Armada 3700 by Miquèl Raynal (which is currently
|
|
in linux-next) does not actually set comphy mode when phy_set_mode_ext
|
|
is called. The mode is set at next call of phy_power_on.
|
|
|
|
Update the driver to semantics similar to mvpp2: helper
|
|
mvneta_comphy_init sets comphy mode and powers it on.
|
|
When mode is to be changed in mvneta_mac_config, first power the comphy
|
|
off, then call mvneta_comphy_init (which sets the mode to new one).
|
|
|
|
Only do this when new mode is different from old mode.
|
|
|
|
This should also work for Armada 38x, since in that comphy driver
|
|
methods power_on and power_off are unimplemented.
