/*
|
|
* 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)
