Wolfram, I am sending you the i2c-slave-mqueue driver. Apparently Haiyue had to move on to another project and does not have cycles to continue with the comments on this driver after some time waiting for feedback, that is essentially why I took over. Here is a small changelog from V5 to V6: - Added DT support for probing via Device Tree - Docummented DT bindings - Documented sysfs ABI - Small fixes on wording and Kconfig entries. Haiyue's V5: https://lkml.org/lkml/2018/4/23/835 BR, Eduardo Valentin (2): dt-bindings: i2c: document bindings for i2c-slave-mqueue Documentation: ABI: Add i2c-slave-mqueue sysfs documentation Haiyue Wang (1): i2c: slave-mqueue: add a slave backend to receive and queue messages .../sysfs-bus-i2c-devices-slave-mqueue | 10 + .../bindings/i2c/i2c-slave-mqueue.txt | 34 +++ Documentation/i2c/slave-mqueue-backend.rst | 124 ++++++++++ MAINTAINERS | 8 + drivers/i2c/Kconfig | 25 +++ drivers/i2c/Makefile | 1 + drivers/i2c/i2c-slave-mqueue.c | 211 ++++++++++++++++++ 7 files changed, 413 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-bus-i2c-devices-slave-mqueue create mode 100644 Documentation/devicetree/bindings/i2c/i2c-slave-mqueue.txt create mode 100644 Documentation/i2c/slave-mqueue-backend.rst create mode 100644 drivers/i2c/i2c-slave-mqueue.c -- 2.21.0
