27 * build IOMUX_PAD structure
29 * This iomux scheme is based around pads, which are the physical balls
32 * - Each pad has a pad control register (IOMUXC_SW_PAD_CTRL_x) which controls
33 * things like driving strength and pullup/pulldown.
34 * - Each pad can have but not necessarily does have an output routing register
35 * (IOMUXC_SW_MUX_CTL_PAD_x).
36 * - Each pad can have but not necessarily does have an input routing register
37 * (IOMUXC_x_SELECT_INPUT)
39 * The three register sets do not have a fixed offset to each other,
40 * hence we order this table by pad control registers (which all pads
41 * have) and put the optional i/o routing registers into additional
44 * The naming convention for the pad modes is SOC_PAD_<padname>__<padmode>
45 * If <padname> or <padmode> refers to a GPIO, it is named GPIO_<unit>_<num>
47 * IOMUX/PAD Bit field definitions
49 * MUX_CTRL_OFS: 0..11 (12)
50 * PAD_CTRL_OFS: 12..23 (12)
51 * SEL_INPUT_OFS: 24..35 (12)
