ipmi: bt-bmc: Use a regmap for register access

2017-02-20T17:00:48Z

The registers for the bt-bmc device live under the Aspeed LPC controller. Devicetree bindings have recently been introduced for the LPC controller where the "host" portion of the LPC register space is described as a syscon device. Future devicetrees describing the bt-bmc device should nest its node under the appropriate "simple-mfd", "syscon" compatible node. This change allows the bt-bmc driver to function with both syscon and non-syscon- based devicetree descriptions by always using a regmap for register access, either retrieved from the parent syscon device or instantiated if none exists.

char: ipmi: constify ipmi_smi_handlers structures

2017-02-09T15:10:56Z

Declare ipmi_smi_handlers structures as const as they are only passed as an argument to the function ipmi_register_smi. This argument is of type const, so ipmi_smi_handlers structures having similar properties can be declared const too.

Pull IPMI updates from Corey Minyard: "Various small fixes for IPMI. Cleanups in the documentation and convertion printk() to pr_xxx() and removal of an unused module parameter. Some small bug fixes and enhancements. This also adds a post softdep from the IPMI core module to the IPMI device interface. Many people have complained that the device interface isn't automatically avaiable when IPMI is loaded. I don't want to make the device interface mandatory, though, plenty of people use IPMI internally (like with ACPI) and don't need a device interface or the added possible security entry. A softdep should make it work 'out of the box' but allow people to not have it if they don't want it" * tag 'for-linus-4.10' of git://git.code.sf.net/p/openipmi/linux-ipmi: ipmi: create hardware-independent softdep for ipmi_devintf ipmi: Fix sequence number handling ipmi: Pick up slave address from SMBIOS on an ACPI device ipmi_si: Clean up printks Move platform device creation earlier in the initialization ipmi: Update documentation ipmi_ssif: Remove an unused module parameter ipmi: Periodically check for events, not messages

ipmi: create hardware-independent softdep for ipmi_devintf

2016-12-12T20:26:29Z

When a computer has an IPMI system interface, the device interface is most probably also desired. Autoloading of ipmi_devintf currently works only if ipmi_si has allocated a platform device. That doesn't happen if the SI interface was detected e.g. via ACPI. But ACPI detection is preferred these days, see e.g. kernel.org bug 46741. This patch introduces a softdep in place of the existing modalias for ipmi_devintf. Signed-off-by: Martin Wilck Suggested-by: Takashi Iwai I moved this to ipmi_msghandler.c, so it works for all IPMI interfaces. Retested by Martin.

ipmi: Fix sequence number handling

2016-11-25T00:09:49Z

The IPMI message handler uses a message id that the lower-layer preserved to track the sequence number of the message. The macros that handled these sequence numbers were somewhat broken as they could result in sequence number truncation and they were not doing an "and" of the proper number of bits. I think this actually is not a problem, because the truncation should be harmless and the improper "and" didn't hurt anything because sequence number generation used the same improper "and" and wouldn't generate a sequence number that would get truncated wrong. However, it should be fixed. Reported-by: Dan Carpenter Signed-off-by: Corey Minyard

ipmi: Pick up slave address from SMBIOS on an ACPI device

2016-11-25T00:09:48Z

When added by ACPI, the information does not contain the slave address of the BMC. However, that information is available from SMBIOS. So if we add a device that doesn't have a slave address, look at the other devices that are duplicate interfaces and see if they have a slave address. Signed-off-by: Corey Minyard
