   4 Subject: arm: mvebu: define and use common Armada XP SPI pinctrl setting
   5
   6 This patch defines common Armada XP pinctrl settings in armada-xp.dtsi
   7 for the supported SPI interface (MPP36-39) and use it as default
   8 for Armada XP spi interface. That being done, it removes the now
   9 redundant definitions in armada-xp-axpwifiap.dts.
  10
  11 Note: this patch has the potential to break out-of-tree users w/o
  12 specific pinctrl settings for their spi interfaces if the default
  13 above does not match their config (i.e. if they do not use CS0).
