Hi, This patch series adds a netdev driver providing MCTP transport over I2C. It applies against net-next using recent MCTP changes there, though also has I2C core changes for review. I'll leave it to maintainers where it should be applied - please let me know if it needs to be submitted differently. The I2C patches were previously sent as RFC though the only feedback there was an ack to 255 bytes for aspeed. The dt-bindings patch went through review on the list. Cheers, Matt -- v3: - Added Reviewed-bys for npcm7xx - Resend with net-next open v2: - Simpler Kconfig condition for i2c-mux dependency, from Randy Dunlap Matt Johnston (6): i2c: core: Allow 255 byte transfers for SMBus 3.x i2c: dev: Handle 255 byte blocks for i2c ioctl i2c: aspeed: Allow 255 byte block transfers i2c: npcm7xx: Allow 255 byte block SMBus transfers 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/i2c/busses/i2c-aspeed.c | 5 +- drivers/i2c/busses/i2c-npcm7xx.c | 3 +- drivers/i2c/i2c-core-smbus.c | 20 +- drivers/i2c/i2c-dev.c | 93 +- drivers/net/mctp/Kconfig | 12 + drivers/net/mctp/Makefile | 1 + drivers/net/mctp/mctp-i2c.c | 982 ++++++++++++++++++ include/linux/i2c.h | 13 + include/uapi/linux/i2c-dev.h | 2 + include/uapi/linux/i2c.h | 7 +- 12 files changed, 1209 insertions(+), 25 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/mctp-i2c-controller.yaml create mode 100644 drivers/net/mctp/mctp-i2c.c -- 2.32.0
