This patch set adds support for the HMS Industrial Networks AB Profinet card. Profinet is an industry technical standard for data communication over Industrial Ethernet, designed for collecting data from, and controlling, equipment in industrial systems, with a particular strength in delivering data under tight time constraints (on the order of 1ms or less). The profinet card itself is connected to the system via an industrial bus called 'anybus'. I have followed the bus driver/client driver pattern, and created an anybus bus driver, plus a client driver for the profinet card. In case this patch set gets (eventually) accepted, drivers for other anybus client cards may follow: flnet, cc-link, ... The anybus slot on the host is located on an 'anybus bridge', which is custom h/w designed by Arcx. Its driver is modeled as an mfd, which instantiates two anybus slots. v1: first shot Sven Van Asbroeck (4): mfd: support the Arcx anybus bridge. dt-bindings: anybus-bridge: document devicetree binding. bus: support HMS Anybus-S bus. misc: support HMS Profinet IRT industrial controller. .../bindings/mfd/arcx,anybus-bridge.txt | 37 + .../devicetree/bindings/vendor-prefixes.txt | 1 + drivers/bus/Kconfig | 11 + drivers/bus/Makefile | 1 + drivers/bus/anybuss-host.c | 1301 +++++++++++++++++ drivers/mfd/Kconfig | 11 + drivers/mfd/Makefile | 1 + drivers/mfd/anybus-bridge.c | 441 ++++++ drivers/misc/Kconfig | 11 + drivers/misc/Makefile | 1 + drivers/misc/hms-profinet.c | 747 ++++++++++ include/linux/anybuss-client.h | 100 ++ include/linux/anybuss-host.h | 28 + include/uapi/linux/hms-common.h | 14 + include/uapi/linux/hms-profinet.h | 101 ++ 15 files changed, 2806 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/arcx,anybus-bridge.txt create mode 100644 drivers/bus/anybuss-host.c create mode 100644 drivers/mfd/anybus-bridge.c create mode 100644 drivers/misc/hms-profinet.c create mode 100644 include/linux/anybuss-client.h create mode 100644 include/linux/anybuss-host.h create mode 100644 include/uapi/linux/hms-common.h create mode 100644 include/uapi/linux/hms-profinet.h -- 2.17.1
