- Subject: [PATCH] net: dsa: bcm_sf2: enable GPHY for switch probing
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- GPHY needs to be enabled to succesfully probe & setup switch port
- connected to it. Otherwise hardcoding PHY OUI would be required.
- Before:
- brcm-sf2 80080000.switch lan4 (uninitialized): PHY [800c05c0.mdio--1:08] driver [Generic PHY] (irq=POLL)
- brcm-sf2 80080000.switch lan3 (uninitialized): PHY [800c05c0.mdio--1:09] driver [Generic PHY] (irq=POLL)
- brcm-sf2 80080000.switch lan2 (uninitialized): PHY [800c05c0.mdio--1:0a] driver [Generic PHY] (irq=POLL)
- brcm-sf2 80080000.switch lan1 (uninitialized): PHY [800c05c0.mdio--1:0b] driver [Generic PHY] (irq=POLL)
- brcm-sf2 80080000.switch wan (uninitialized): error -5 setting up PHY for tree 0, switch 0, port 7
- After:
- brcm-sf2 80080000.switch lan4 (uninitialized): PHY [800c05c0.mdio--1:08] driver [Generic PHY] (irq=POLL)
- brcm-sf2 80080000.switch lan3 (uninitialized): PHY [800c05c0.mdio--1:09] driver [Generic PHY] (irq=POLL)
- brcm-sf2 80080000.switch lan2 (uninitialized): PHY [800c05c0.mdio--1:0a] driver [Generic PHY] (irq=POLL)
- brcm-sf2 80080000.switch lan1 (uninitialized): PHY [800c05c0.mdio--1:0b] driver [Generic PHY] (irq=POLL)
- brcm-sf2 80080000.switch wan (uninitialized): PHY [800c05c0.mdio--1:0c] driver [Generic PHY] (irq=POLL)
