[Openipmi-developer] [PATCH v2 2/4] ipmi: bt-i2c: added IPMI Block Transfer over I2C host side

The IPMI definition of the Block Transfer protocol defines the hardware registers and behavior in addition to the message format and messaging semantics. This implements a new protocol that uses IPMI Block Transfer messages and semantics on top of a standard I2C interface. Signed-off-by: Brendan

[Openipmi-developer] [PATCH v1 1/3] ipmi: bt-i2c: added documentation for bt-i2c drivers

Added device tree binding documentation for ipmi-bt-i2c (host) and ipmi-bmc-bt-i2c (BMC) and documentation for the Block Transfer over I2C (bt-i2c) protocol. Signed-off-by: Brendan Higgins --- Documentation/bt-i2c.txt | 121

[Openipmi-developer] [PATCH v2 4/4] ipmi: bt-bmc: move Aspeed IPMI BMC driver to ipmi_bmc

From: Benjamin Fair The ipmi_bmc folder contains drivers for a BMC to communicate using IPMI. The ipmi folder is only for drivers on the host side using the OpenIPMI framework. Signed-off-by: Benjamin Fair Signed-off-by: Brendan Higgins

[Openipmi-developer] [PATCH v2 1/4] ipmi: bt-i2c: added documentation for bt-i2c drivers

Added device tree binding documentation for ipmi-bt-i2c (host) and ipmi-bmc-bt-i2c (BMC) and documentation for the Block Transfer over I2C (bt-i2c) protocol. Signed-off-by: Brendan Higgins --- Changes for v2: - Fixed a typo - Reworded a sentence to make it clear

[Openipmi-developer] [PATCH v2 0/4] ipmi: bt-i2c: added IPMI Block Transfer over I2C

This patchset introduces IPMI Block Transfer over I2C (BT-I2C), which has the same semantics as IPMI Block Transfer except it done over I2C. For the OpenBMC people, this is based on an RFC: https://lists.ozlabs.org/pipermail/openbmc/2016-September/004505.html The documentation discusses the

[Openipmi-developer] [RFC v1 1/4] ipmi_bmc: framework for BT IPMI on BMCs

From: Benjamin Fair This patch introduces a framework for writing IPMI drivers which run on a Board Management Controller. It is similar in function to OpenIPMI. The framework handles registering devices and routing messages. Signed-off-by: Benjamin Fair

[Openipmi-developer] [RFC v1 3/4] ipmi_bmc: bt-i2c: port driver to IPMI BMC framework

From: Benjamin Fair Instead of handling interaction with userspace and providing a file interface, rely on the IPMI BMC framework to do this. This simplifies the logic and eliminates duplicate code. Signed-off-by: Benjamin Fair Signed-off-by:
