Merge tag 'soc_drivers_for_4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux-keystone into next/drivers

ARM: SOC driver update for 4.18

 - AEMIF driver update to support board files and remove
   need of mach-davinci aemif code
 - Use percpu counters for qmss datapath stats
 - License update for TI SCI

* tag 'soc_drivers_for_4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux-keystone:
  firmware: ti_sci: Switch to SPDX Licensing
  soc: ti: knav_qmss: Use percpu instead atomic for stats counter
  memory: aemif: add support for board files
  memory: aemif: don't rely on kbuild for driver's name
