| /* |
| * 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 + LPSR: 36..41 (6) |
| * PAD_CTRL + NO_PAD_CTRL: 42..59 (18) |
| * SEL_INP: 60..63 (4) |
