/*
* 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>
*
* IOMUX/PAD Bit field definitions
*
* MUX_CTRL_OFS: 0..11 (12)
* PAD_CTRL_OFS: 12..23 (12)
* SEL_INPUT_OFS: 24..35 (12)
* MUX_MODE + SION: 36..40 (5)
* PAD_CTRL + NO_PAD_CTRL: 41..58 (18)
* SEL_INP: 59..62 (4)
* reserved: 63 (1)
