This series add support for the Aspeed specific SSIF BMC driver which
is to perform in-band IPMI communication with the host in management
(BMC) side.

v3:
  + Switched binding doc to use DT schema format [Rob]
  + Splited into generic ssif_bmc and aspeed-specific [Corey, Joel]
  + Removed redundant license info [Joel]
  + Switched to use traditional if-else [Joel]
  + Removed unused ssif_bmc_ioctl() [Joel]
  + Made handle_request()/complete_response() to return void [Joel]
  + Refactored send_ssif_bmc_response()/receive_ssif_bmc_request() [Corey]
  + Remove mutex [Corey]
  + Use spin_lock/unlock_irqsave/restore in callback [Corey]
  + Removed the unnecessary memset [Corey]
  + Switch to use dev_err() [Corey]
  + Combine mask/unmask two interrupts together [Corey]
  + Fixed unhandled Tx done with NAK [Quan]
  + Late ack'ed Tx done w/wo Ack irq [Quan]
  + Use aspeed-specific exported aspeed_set_slave_busy() when slave busy
to fix the deadlock [Graeme, Philipp, Quan]
  + Clean buffer for last multipart read [Quan]
  + Handle unknown incoming command [Quan]

v2:
  + Fixed compiling error with COMPILE_TEST for arc

Note that for this I2C-specific change, I will need acks from the I2C
maintainers to be able to include this in my tree.

For the aspeed changes, they don't really belong here, they belong in
the aspeed tree.  I see that you need them for the device to work
correctly, though.  I'll need acks from maintainers to include them.

Thanks for you information.
Will separate these i2c-aspeed's patches into other independent series 
in next version.
