Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 

Pull ARM SoC fixes from Arnd Bergmann:
 "A small number of bugfixes, again nothing serious.

   - Alexander Dahl found multiple bugs in the Atmel memory interface
     driver

   - A randconfig build fix for at91 was incomplete, the second attempt
     fixes the remaining corner case

   - One fix for the TI Keystone queue handler

   - The Odroid XU4 HDMI port (added in 4.13) needs a small DT fix"
