Subject: [PATCH] net: dsa: mt7530: do not set MT7530_P5_DIS when PHY muxing is
|
||
being used
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8

|
||
|
||
DSA initalises the ds->num_ports amount of ports in
|
||
dsa_switch_touch_ports(). When the PHY muxing feature is in use, port 5
|
||
won't be defined in the device tree. Because of this, the type member of
|
||
the dsa_port structure for this port will be assigned DSA_PORT_TYPE_UNUSED.
|
||
The dsa_port_setup() function calls ds->ops->port_disable() when the port
|
||
type is DSA_PORT_TYPE_UNUSED.
|
||
|
||
The MT7530_P5_DIS bit is unset in mt7530_setup() when PHY muxing is being
|
||
used. mt7530_port_disable() which is assigned to ds->ops->port_disable() is
|
||
called afterwards. Currently, mt7530_port_disable() sets MT7530_P5_DIS
|
||
which breaks network connectivity when PHY muxing is being used.
|
||
|
||
Therefore, do not set MT7530_P5_DIS when PHY muxing is being used.
|
||
|
