Agenda

• Introduction and motivation
• Mainline switchdev support
• Mainline Linux kernel TN48M-P-DN support and upstreaming
• Updates on EdgeCore AS5114-48X switch
• PoE functionality breakdown (high-level, low-level)
• Upcoming systemd activities
• Upstream quirks

TN48M-P-DN

Sent upstream:

• TI TMP1075 temperature sensor
• CPLD drivers:
  • MFD
  • GPIO
  • hwmon
• DPS920AB PSU PMBus
• Appropriate documentation and DT bindings

Feeedback for v1 patchset received:

• TI TMP1075 support merged
• Some PMBus driver remarks
• hwmon driver remarks: PSU PG status not suited for hwmon More things need to be added or PG moved
• MFD suggestion about simple-mfd-i2c
• GPIO suggested simplified GPIO indexes suggested
• Most DT Bindings approved

AS5114-48X

This is the status as of today with the items that are tested and working:

• Console
• USB
• Management ethernet
• CPLD MFD driver
• CPLD GPIO driver
• MAC parsing from EEPROM
• Switch with SFP+ ports
• Temperature sensors
• TPM
• I2C buses
• I2C multiplexing
• SATA

Currently under development are the following items:

• Fan monitoring
• Fan control

systemd

Bridge MAC inheritance issue [github #19559]

Actions

Marvell to check internally regarding the Prestera driver upstream activities.
