 /*
  *	build IOMUX_PAD structure
  *
  * This iomux scheme is based around pads, which are the physical balls
  * on the processor.
  *
  * - Each pad has a pad control register (IOMUXC_SW_PAD_CTRL_x) which controls
  *   things like driving strength and pullup/pulldown.
  * - Each pad can have but not necessarily does have an output routing register
  *   (IOMUXC_SW_MUX_CTL_PAD_x).
  * - Each pad can have but not necessarily does have an input routing register
  *   (IOMUXC_x_SELECT_INPUT)
  *
  * The three register sets do not have a fixed offset to each other,
  * hence we order this table by pad control registers (which all pads
  * have) and put the optional i/o routing registers into additional
  * fields.
  *
  * The naming convention for the pad modes is SOC_PAD_<padname>__<padmode>
  * If <padname> or <padmode> refers to a GPIO, it is named GPIO_<unit>_<num>
  *
