Merge branch 'binding-doc-cp110-ap806' of git://git.infradead.org/linux-mvebu into clk-next 

* 'binding-doc-cp110-ap806' of git://git.infradead.org/linux-mvebu:
  gpio: dt-bindings: Add documentation for gpio controllers on Armada 7K/8K
  pinctrl: dt-bindings: add documentation for CP110 pin controllers
  pinctrl: dt-bindings: add documentation for AP806 pin controllers
  dt-bindings: cp110: add sdio clock to cp-110 system controller
  dt-bindings: cp110: introduce a new binding
  dt-bindings: cp110: do not depend anymore of the *-clock-output-names
