Subject: pinctrl: zynq: Initialize early
X-Git-Tag: v4.4-rc1~171^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=13e3008fae342c86dd645b2ec4c669bbb40c5d33;p=profile%2Fcommon%2Fplatform%2Fkernel%2Flinux-artik7.git

pinctrl: zynq: Initialize early

Supplying pinmux configuration for e.g. gpio pins leads to deferred
probes because the pinctrl device is probed much later than gpio.
Move the init call to a much earlier stage so it probes before the
devices that may need it.
