    pinctrl: fsl: add scu based pinctrl support · b96eea71
    A.s. Dong authored
    Some i.MX SoCs (e.g. MX8QXP and MX8QM) contain a system controller
    that is responsible for controlling the pad setting of the IPs that
    are present. Communication between the host processor running an OS
    and the system controller happens through a SCU protocol.
    
    This patch classifies the pad settings into two categories: MMIO and SCU.
    For the original MMIO method, no functional changes except organize them
    into a few imx_*_mmio() functions. Besides that, we add the SCU based
    Pad Mux and Pinconf setting support which are implemented in pinctrl-scu.c.
