This patch series adds a netdev driver providing MCTP transport over I2C. I think I've addressed all the points raised in v5. It now has mctp_i2c_unregister() to run things in the correct order, waiting for the worker thread and I2C rx to complete. Cheers, Matt -- v6: - Changed netdev register/unregister/free to avoid races. Ensure that netif functions are not used by irq handler/threads after unregister. - Fix incoming I2C hwaddr that was previously incorrect (left shifted 1 bit) - Add a check that byte_count wire header matches the length received - Renamed I2C driver to mctp-i2c-interface - Removed __func__ from print messages, added missing newlines - Removed sysfs mctp_current_mux file which was used for debug - Renamed curr_lock to sel_lock - Tidied comment formatting - Fix newline in Kconfig v5: - Fix incorrect format string v4: - Switch to __i2c_transfer() rather than __i2c_smbus_xfer(), drop 255 byte smbus patches - Use wait_event_idle() for the sleeping TX thread - Use dev_addr_set() v3: - Added Reviewed-bys for npcm7xx - Resend with net-next open v2: - Simpler Kconfig condition for i2c-mux dependency, from Randy Dunlap Matt Johnston (2): dt-bindings: net: New binding mctp-i2c-controller mctp i2c: MCTP I2C binding driver Documentation/devicetree/bindings/i2c/i2c.txt | 4 + .../bindings/net/mctp-i2c-controller.yaml | 92 ++ drivers/net/mctp/Kconfig | 12 + drivers/net/mctp/Makefile | 1 + drivers/net/mctp/mctp-i2c.c | 1081 +++++++++++++++++ 5 files changed, 1190 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/mctp-i2c-controller.yaml create mode 100644 drivers/net/mctp/mctp-i2c.c -- 2.32.0
