Merge branch 'spear/pinctrl' into next/pinctrl
* spear/pinctrl:
pinctrl: (cosmetic) fix two entries in DocBook comments
pinctrl: add more info to error msgs in pin_request
CLKDEV: provide helpers for common clock framework
pinctrl: add pinctrl-mxs support
pinctrl: pinctrl-imx: add imx6q pinctrl driver
pinctrl: pinctrl-imx: add imx pinctrl core driver
dt: add of_get_child_count helper function
pinctrl: support gpio request deferred probing
pinctrl: add pinctrl_provide_dummies interface for platforms to use
pinctrl: enhance reporting of errors when loading from DT
pinctrl: add kerneldoc for pinctrl_ops device tree functions
pinctrl: propagate map validation errors
pinctrl: fix dangling comment
pinctrl: fix signed vs unsigned conditionals inside pinmux_map_to_setting
ARM: 7392/1: CLKDEV: Optimize clk_find()
ARM: 7376/1: clkdev: Implement managed clk_get()
This just adds more dependencies that are required in order not to
break the spear pinctrl support.
