Subject: [PATCH] ARM: dts: BCM53573: Fix Ethernet info for Luxul devices
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

|
Both Luxul's XAP devices (XAP-810 and XAP-1440) are access points that
|
|
use a non-default design. They don't include switch but have a single
|
|
Ethernet port and BCM54210E PHY connected to the Ethernet controller's
|
|
MDIO bus.
|
|
|
|
Support for those devices regressed due to two changes:
|
|
|
|
1. Describing MDIO bus with switch
|
|
After commit 9fb90ae6cae7 ("ARM: dts: BCM53573: Describe on-SoC BCM53125
|
|
rev 4 switch") Linux stopped probing for MDIO devices.
|
|
|
|
2. Dropping hardcoded BCM54210E delays
|
|
In commit fea7fda7f50a ("net: phy: broadcom: Fix RGMII delays
|
|
configuration for BCM54210E") support for other PHY modes was added but
|
|
that requires a proper "phy-mode" value in DT.
|
|
|
|
Both above changes are correct (they don't need to be reverted or
|
|
anything) but they need this fix for DT data to be correct and for Linux
|
|
to work properly.
|
|
|
|
Fixes: 9fb90ae6cae7 ("ARM: dts: BCM53573: Describe on-SoC BCM53125 rev 4 switch")
