    pinctrl: imx: detect uninitialized pins · 3dac1918
    Stefan Agner authored
    The pinctrl driver initialized the register offsets for the pins
    with 0. On Vybrid an offset of 0 is a valid offset for the pinctrl
    mux register. So far, this was solved using the ZERO_OFFSET_VALID
    flag which allowed offsets of 0. However, this does not allow to
    verify whether a pins struct imx_pmx_func was initialized or not.
    
    Use signed offset values for register offsets and initialize those
    with -1 in order to detect uninitialized offset values reliable.
