ipmi: Remove the proc interface

2018-05-09T17:21:46+00:00

It has been deprecated long enough, get rid of it.

ipmi: add an NPCM7xx KCS BMC driver

2018-04-18T15:23:12+00:00

This driver exposes the Keyboard Controller Style (KCS) interface on
Novoton NPCM7xx SoCs as a character device. Such SOCs are commonly used
as a BaseBoard Management Controller (BMC) on a server board, and KCS
interface is commonly used to perform the in-band IPMI communication
between the server and its BMC.

ipmi: add an Aspeed KCS IPMI BMC driver

2018-02-26T15:21:28+00:00

The KCS (Keyboard Controller Style) interface is used to perform in-band
IPMI communication between a server host and its BMC (BaseBoard Management
Controllers).

This driver exposes the KCS interface on ASpeed SOCs (AST2400 and AST2500)
as a character device. Such SOCs are commonly used as BMCs and this driver
implements the BMC side of the KCS interface.

ipmi: add a KCS IPMI BMC driver

2018-02-26T15:21:28+00:00

Provides a device driver for the KCS (Keyboard Controller Style)
IPMI interface which meets the requirement of the BMC (Baseboard
Management Controllers) side for handling the IPMI request from
host system software.

[Removed the selectability of IPMI_KCS_BMC, as it doesn't do much
 good to have it by itself.]

ipmi: Make the IPMI proc interface configurable

ipmi: Make IPMI panic strings always available

2017-09-27T21:03:45+00:00

They were set by config items, but people complained that they were
never turned on.  So have them always available and enabled by a
module parameter.

ipmi: Create a platform device for a DMI-specified IPMI interface

2017-06-19T17:49:36+00:00

Create a platform device for each IPMI device in the DMI table,
a separate kind of device for SSIF types and for KCS, BT, and
SMIC types.  This is so auto-loading IPMI devices will work
from just SMBIOS tables.

This also adds the ability to extract the slave address from
the SMBIOS tables, so that when the driver uses ACPI-specified
interfaces, it can still extract the slave address from SMBIOS.

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

2017-02-20T17:00:48+00:00

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.

ipmi: add an Aspeed BT IPMI BMC driver

2016-09-30T00:05:06+00:00

This patch adds a simple device driver to expose the iBT interface on
Aspeed SOCs (AST2400 and AST2500) as a character device. Such SOCs are
commonly used as BMCs (BaseBoard Management Controllers) and this
driver implements the BMC side of the BT interface.

The BT (Block Transfer) interface is used to perform in-band IPMI
communication between a host and its BMC. Entire messages are buffered
before sending a notification to the other end, host or BMC, that
there is data to be read. Usually, the host emits requests and the BMC
responses but the specification provides a mean for the BMC to send
SMS Attention (BMC-to-Host attention or System Management Software
attention) messages.

For this purpose, the driver introduces a specific ioctl on the
device: 'BT_BMC_IOCTL_SMS_ATN' that can be used by the system running
on the BMC to signal the host of such an event.

The device name defaults to '/dev/ipmi-bt-host'

[clg: - checkpatch fixes
      - added a devicetree binding documentation
      - replace 'bt_host' by 'bt_bmc' to reflect that the driver is
        the BMC side of the IPMI BT interface
      - renamed the device to 'ipmi-bt-host'
      - introduced a temporary buffer to copy_{to,from}_user
      - used platform_get_irq()
      - moved the driver under drivers/char/ipmi/ but kept it as a misc
        device
      - changed the compatible cell to "aspeed,ast2400-bt-bmc"
