Message-ID: <1454305105-4372-2-git-send-email-van.freenix@gmail.com> (raw)

Introudce i.MX7 pinctrl driver support.
For now only i.MX7D supported.
There are two iomux controllers in i.MX7D, iomuxc and iomuxc_lpsr.
To iomuxc_lpsr, ZERO_OFFSET_VALID is set, means offset of mux_reg
and conf_reg can begin at 0.
