Hello Greg, Linus, Greg, I didn't get your feedback on v10 of the i3c patchset [1] where I was asking if you'd agree to have this framework merged in 4.20 (I know you were busy with the 4.19 release and after that the Kernel Summit, so that's not a surprise), so I'm sending this PR. It's really not an attempt to bypass you, more like a ping that, if positively acknowledged, might lead to inclusion of the I3C framework in 4.20 (5.0?) :-).
Please let me know if you're opposed to the idea. Regards, Boris [1]https://lkml.org/lkml/2018/10/26/552 The following changes since commit 5b394b2ddf0347bef56e50c69a58773c94343ff3: Linux 4.19-rc1 (2018-08-26 14:11:59 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux.git tags/i3c/for-4.20 for you to fetch changes up to 71e60757e1eab6f7b821585948317961ccdc61d1: dt-bindings: i3c: Document Cadence I3C master bindings (2018-11-01 06:12:05 +0100) ---------------------------------------------------------------- Add the I3C framework + an I3C controller driver for Cadence IP ---------------------------------------------------------------- Boris Brezillon (7): i3c: Add core I3C infrastructure docs: driver-api: Add I3C documentation i3c: Add sysfs ABI spec dt-bindings: i3c: Document core bindings MAINTAINERS: Add myself as the I3C subsystem maintainer i3c: master: Add driver for Cadence IP dt-bindings: i3c: Document Cadence I3C master bindings Documentation/ABI/testing/sysfs-bus-i3c | 146 ++ Documentation/devicetree/bindings/i3c/cdns,i3c-master.txt | 44 + Documentation/devicetree/bindings/i3c/i3c.txt | 139 ++ Documentation/driver-api/i3c/device-driver-api.rst | 9 + Documentation/driver-api/i3c/index.rst | 11 + Documentation/driver-api/i3c/master-driver-api.rst | 10 + Documentation/driver-api/i3c/protocol.rst | 203 +++ Documentation/driver-api/index.rst | 1 + MAINTAINERS | 12 + drivers/Kconfig | 2 + drivers/Makefile | 2 +- drivers/i3c/Kconfig | 24 + drivers/i3c/Makefile | 4 + drivers/i3c/device.c | 233 ++++ drivers/i3c/internals.h | 26 + drivers/i3c/master.c | 2661 +++++++++++++++++++++++++++++++++++++ drivers/i3c/master/Kconfig | 6 + drivers/i3c/master/Makefile | 1 + drivers/i3c/master/i3c-master-cdns.c | 1671 +++++++++++++++++++++++ include/linux/i3c/ccc.h | 385 ++++++ include/linux/i3c/device.h | 331 +++++ include/linux/i3c/master.h | 648 +++++++++ include/linux/mod_devicetable.h | 17 + 23 files changed, 6585 insertions(+), 1 deletion(-) create mode 100644 Documentation/ABI/testing/sysfs-bus-i3c create mode 100644 Documentation/devicetree/bindings/i3c/cdns,i3c-master.txt create mode 100644 Documentation/devicetree/bindings/i3c/i3c.txt create mode 100644 Documentation/driver-api/i3c/device-driver-api.rst create mode 100644 Documentation/driver-api/i3c/index.rst create mode 100644 Documentation/driver-api/i3c/master-driver-api.rst create mode 100644 Documentation/driver-api/i3c/protocol.rst create mode 100644 drivers/i3c/Kconfig create mode 100644 drivers/i3c/Makefile create mode 100644 drivers/i3c/device.c create mode 100644 drivers/i3c/internals.h create mode 100644 drivers/i3c/master.c create mode 100644 drivers/i3c/master/Kconfig create mode 100644 drivers/i3c/master/Makefile create mode 100644 drivers/i3c/master/i3c-master-cdns.c create mode 100644 include/linux/i3c/ccc.h create mode 100644 include/linux/i3c/device.h create mode 100644 include/linux/i3c/master.h
