address of the panic generator (byte 4 of the event), a sequence

ipmi: add an Aspeed BT IPMI BMC driver 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' Signed-off-by: Alistair Popple <alistair@popple.id.au> Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Joel Stanley <joel@jms.id.au> [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" ] Signed-off-by: Cédric Le Goater <clg@kaod.org> Acked-by: Arnd Bergmann <arnd@arndb.de> [clg: - checkpatch --strict fixes - removed the use of devm_iounmap, devm_kfree in cleanup paths - introduced an atomic-t to limit opens to 1 - introduced a mutex to protect write/read operations] Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Cédric Le Goater <clg@kaod.org> Signed-off-by: Corey Minyard <cminyard@mvista.com>

ipmi: kcs_bmc: Add serio adaptor kcs_bmc_serio acts as a bridge between the KCS drivers in the IPMI subsystem and the existing userspace interfaces available through the serio subsystem. This is useful when userspace would like to make use of the BMC KCS devices for purposes that aren't IPMI.

tristate "SerIO adaptor for BMC KCS devices"
help
Adapts the BMC KCS device for the SerIO subsystem. This allows users
to take advantage of userspace interfaces provided by SerIO where
appropriate.
Say YES if you wish to expose KCS devices on the BMC via SerIO
interfaces.
This support is also available as a module. The module will be
called kcs_bmc_serio.
ipmi: add an Aspeed BT IPMI BMC driver 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.

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