2015-10-22watchdog/aspeed_wdt: Set system reset mode to 'full chip'Jeremy Kerr1-1/+3
Currently, the watchdog timer does nothing on expiry - the 'SoC system' reset type doesn't seem to have any effect. This change uses the 'full chip' reset type instead. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
2015-10-22watchdog/aspeed_wdt: Move watchdog reset to a separate functionJeremy Kerr1-12/+14
We do the same reset procedure in apeed_wdt_enable and our reboot notifier, so move these to a separate function. Also, use a couple of definitions for the watchdog control value rather than a hardcoded '3'. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>

2015-10-16arm/mach-aspeed: Enable UART clock divisorJeremy Kerr1-0/+10

2015-10-06net/faraday: Enable offload checksum according to device-treeGavin Shan1-1/+5
This enables IP/UDP/TCP offload checksum according to information passed on from bootloader through device-tree. The offload doesn't working properly when the interface works in NCSI mode. Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com>
2015-10-06net/faraday: Enable NCSI interfaceGavin Shan1-24/+67
The NIC has the possibility to connect to NCSI package and channel. This supports NCSI enabled interface. When the network device is registered, the accompanying NCSI device is registered. When the interface is to be brought up, the NCSI device is started to probe NCSI topology and choose one active channel automatically. On the other handle, when the interface is to be brought down, the interface will be shuted down when the NCSI device is teared down. Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com>
2015-10-06net/faraday: Replace use_nc_si with use_ncsiGavin Shan1-7/+7
The patch replaces variable name "use_nc_si" with "use_ncsi". No function changed. Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com>
2015-10-06net/ncsi: Netlink supportGavin Shan6-1/+1105
This adds netlink support so that userland can retrieve the NCSI topology on the specified interface. Also, more netlink commands are introduced to retrieve information from the active channel or configure the active channel with provided options. Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com>
2015-10-06net/ncsi: Manage NCSI deviceGavin Shan4-3/+584
There are multiple packages and channels connecting to NCSI enabled interface. The available packages and channels are probed with NCSI packets when NCSI device is started. Among the available packages and channels, only one channel should be selected to be active to provide service. When the active channel enters to failure state, we need choose another channel as active one to do failover. This implements the state machine to support above tasks. Also, the public interfaces are exposed for NIC driver to manage NCSI device. Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com>
2015-10-06net/ncsi: Packet handlerGavin Shan7-1/+2141
NCSI packet encapsulated in ethernet frame is recognized by the ethernet protocol field (0x88F8). According to NCSI spec, the destination MAC field should be 0xFF's, but the source MAC field could be arbitrary one since channel field in NCSI header indicates the source of the packet. There are 3 types of packets depending on the type field in the NCSI packet header: command, response, Asynchronous Event Notification (AEN). The command packets are sent from NCSI enabled interace to the NCSI package or channel for purpose of information retrival or configuration. The response packets, as responses to the received command packets, originate from NCSI package or channel and terminate at NCSI enabled interface. AEN packets are sent from NCSI channel for asynchronous events that might indicate failure detected on the active channel. This implements the functions to handle NCSI packets.

2015-10-06net/ncsi: Resource managementGavin Shan8-0/+758
According to NCSI spec (DSP0222), the NCSI enabled interface can connected to multiple packages simultaneously, up to 8 packages. Each package includes multiple channels, up to 32 channels. At one moment, one channel is enabled to provide service to the NCSI enabled interface. Besides, each channel comprises capabilities, modes, filters, version and statistics etc. All of them are resources to NCSI protocol stack. At the meanwhile, the NCSI device seen from NIC driver is represented by "struct ncsi_dev", which is expected to populated and started by NIC driver before the NIC can work. All possible NCSI packages and NCSI channels connected to the NCSI interface are tracked from the NCSI device. Also, the NCSI device recognizes active channel that is currently providing service to NCSI enabled interface. Also, the NCSI requests (pairs of command and response) are embedded in NCSI device. This introduces the data structs to represents the NCSI resources mentioned as above. Also, functions used by NCSI stack internally are implemented. Besides, this introduces kernel config option CONFIG_NET_NCSI to enable NCSI stack. Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com>
2015-10-06bt/ipmi: Add Aspeed BT IPMI host driverAlistair Popple4-0/+396

2015-10-06gpio: Move aspeed Kconfig entry to correct menuAlistair Popple1-8/+7
The Aspeed GPIO menu entry was added under "PCI GPIO expanders" which depends on PCI which may not be enabled for Aspeed. Move the entry to the "Memory mapped GPIO drivers" which describes the Aspeed GPIO driver more correctly. Signed-off-by: Alistair Popple <alistair@popple.id.au>
